Mauritius Underwater Waterfall: How to See the Spectacular Illusion at Le Morne
Have you seen those jaw-dropping photos of the Mauritius underwater waterfall illusion off Le Morne Brabant and wondered how to witness it in person? You're in the right place! This comprehensive guide will show you how to see the Mauritius underwater waterfall – whether you're after the best drone view of the underwater waterfall in Mauritius, planning a scenic helicopter tour, or considering a seaplane flight. We’ll cover everything from what this underwater waterfall illusion actually is (is it real?) to the best ways to experience it (helicopter, seaplane, or even by drone), plus tips on how to get to the Le Morne underwater waterfall viewpoint, the best time of year and day to go, and important safety info. Read on for all the details – including convenient local transport options and a handy FAQ – so you can plan an unforgettable trip to Mauritius’ famous underwater waterfall.
What is the Mauritius Underwater Waterfall Illusion?
The “underwater waterfall” of Mauritius is a mesmerizing optical illusion – not a real waterfall at all. Located just off the coast of Le Morne Peninsula at the island’s southwestern tip, this phenomenon looks like a massive subaquatic cascade tumbling into the deep ocean. In reality, no water is actually falling; what you’re seeing is sand and silt sliding down a steep underwater slope into the darker depths. Mauritius sits on an undersea plateau about 150 m shallow, which abruptly drops over 4,000 m into the abyss beyond the ree. Currents continually push sediment off this edge, creating the visual effect of a flowing waterfall beneath the waves. The dramatic contrast between the turquoise lagoon (shallow water) and the deep blue ocean enhances the illusion, making it appear as if the island is “pouring” into the ocean trench.
Despite appearances, the site is perfectly safe to swim or surf above – it’s just normal seawater above a deep drop-off. In fact, Le Morne is a popular spot for kitesurfing and snorkeling, since the “waterfall” is simply a current of sand on the ocean floor. You can only see the illusion from above, either from a height on land or more commonly from the air. This unique natural artwork has become world-famous after satellite images and aerial photos went viral. It’s often featured in travel guides and social media, making it a bucket-list attraction for visitors to Mauritius.
Why Is Mauritius’ Underwater Waterfall Famous?
First, there’s nowhere else in the world quite like it – the illusion is incredibly realistic, looking like a torrent plunging into an underwater canyon. The setting is also stunning: it lies just off Le Morne Brabant, a basaltic mountain rising 556 m above the lagoon that is itself a UNESCO World Heritage Site. The combination of the mountain, the sparkling lagoon, and the “waterfall” effect is a photographer’s dream. Many travelers are amazed that Mauritius – already known for its pristine beaches – hides such a mind-boggling visual phenomenon. It’s frequently asked whether the underwater waterfall is real or fake. The answer: it’s real in appearance but caused by optical illusion, not by actual falling water. This mystique only adds to its fame. Tourists flock to get a glimpse, and it has quickly become one of Mauritius’ top natural attractions.
Best Ways to See the Underwater Waterfall in Mauritius
Since the underwater waterfall can only be truly appreciated from above, the best way to see it is to take to the skies. There are three main ways visitors can get an aerial view:
Helicopter Tours – Quick, exhilarating flights that give you a bird’s-eye view of the waterfall and surrounding sights. This is often cited as the best way to witness the illusion. We’ll cover prices and tour operators in the next section.
Seaplane Flights – A unique adventure where you take off from the water and fly at low altitude over the waterfall. Seaplanes (or ultralight aircraft) offer an intimate one-passenger experience and fantastic photo opportunities.
Drones – For those who have a drone, flying it out over the lagoon can capture the waterfall illusion from above. This option can yield great footage but comes with important safety warnings (high winds, kitesurfers, and low-flying aircraft in the area).
You can’t see the true waterfall effect from ground level at the beach – from the shore or a boat, the ocean just looks normal. However, there is one on-land option: hiking Le Morne Mountain. From the summit of Le Morne Brabant (elevation ~500 m), you get a panoramic view of the reef and lagoon. On clear days you can make out a faint shadow of the underwater waterfall from that vantage. It’s a rewarding hike, but be aware the illusion will appear far in the distance and not as vivid as from an aircraft. To really experience the Mauritius underwater waterfall up close, you’ll want to consider a helicopter or seaplane ride. Let’s dive into each option in detail:
Helicopter Tours: A Thrilling Aerial View of the Underwater Waterfall
Taking a helicopter tour is arguably the best way to see the Mauritius underwater waterfall in all its glory. From a helicopter, you’ll hover right above the spectacle, enjoying an unobstructed 360° view of the cascading sand illusion and the vibrant coral reefs surrounding it. The experience is often described as breathtaking – the combination of the lagoon’s colors and the bird’s-eye perspective of Le Morne Mountain and the Indian Ocean is unforgettable.
What to Expect on a Helicopter Flight: Most sightseeing helicopter flights in Mauritius are relatively short (typically 15 to 30 minutes in the air), focusing on the highlights of the southwest coast. You’ll soar over Le Morne Peninsula and circle above the underwater waterfall multiple times for photos. Many tours also fly over nearby scenic spots such as the lush Chamarel waterfalls and Seven-Colored Earth, the crystal lagoon of Ile aux Benitiers, or along the shoreline of Black River – it depends on the tour route. If you depart from a farther location (like the north or east of the island), longer flight routes will include additional sights en route to Le Morne.
Helicopter Tour Operators & Licensed Services: In Mauritius, helicopter tours are offered by licensed companies and facilitated by the tourism authorities. The national airline Air Mauritius operates sightseeing helicopter flights (often booked through hotels or agents), and there are private operators like Corail Hélicoptères and others specializing in scenic tours. For example, Air Mauritius and partners offer a popular “Underwater Waterfall” flight that departs from the airport and flies direct to Le Morne. Corail Hélicoptères (rated #1 on TripAdvisor) runs a 15-minute “Underwater Waterfall” tour from Chamarel for tourists staying in the south. When choosing a provider, ensure they are an officially licensed operator – all the ones mentioned above are – as this guarantees experienced pilots and proper safety standards.
Helipads and Departure Points: Helicopter tours can take off from various helipads around Mauritius. The main base is at SSR International Airport, but there are helipads at certain resorts and regional airports across the island. If you’re staying at a luxury hotel (e.g. at Le Morne or on the east coast) with its own helipad, you might be able to arrange pickup from there. Otherwise, you’ll be assigned the nearest helipad to your location. Note: Some hotel helipads charge a landing fee for non-guests (ranging from about MUR 2,500 to 5,000). Tour companies will inform you if any landing fee applies; often you pay it on site. If your hotel doesn’t have a helipad, don’t worry – you can easily travel to one (more on transport later), and operators like Mauritius Helicopters can even arrange ground transfers for an extra fee.
Helicopter Tour Prices: The cost of an underwater waterfall helicopter tour depends on the flight duration and whether it’s a shared or private tour. Tours are typically sold as private flights for up to 4 or 5 passengers (depending on helicopter model) – you pay one total price for the group. For example, a private 15-minute scenic flight from a south coast helipad might cost around €1,149–€1,305 total for up to 5 people. That comes out to roughly €230–€260 per person if you have a full group. Departures from the main airport or longer flight routes (about 30 minutes) cost more – approximately €1,625 from the airport for up to 5 passengers.
If you’re a solo traveler or couple, you may not want to charter an entire helicopter. In that case, look for shared helicopter tours where you pay per seat. Some tour companies and online platforms (like GetYourGuide or local agencies) offer these mixed-group flights. As a guideline, a 25–30 minute shared helicopter tour runs about MUR 13,000–15,000 per person (around USD $300+). A slightly longer 45-minute circuit might be ~MUR 18,000 per person. Availability for shared flights can be limited, so inquire in advance.
While not cheap, virtually everyone says it’s worth it. The underwater waterfall is a once-in-a-lifetime sight, and the helicopter ride itself is an exciting adventure. As one traveler put it, yes it “was quite expensive but worth the money…you could see the beautiful coastline and of course the underwater waterfall…we felt very safe and enjoyed the tour very much”. If it fits your budget, we highly recommend the helicopter option for the ultimate view.
Tips for Helicopter Tours:
Book in advance: Helicopter excursions are popular and often get fully booked, especially in peak tourist season (Sept–Dec). Try to reserve your preferred date at least a few days ahead (or before your trip via online booking).
Time of day: Tours operate in daylight, usually ~9:00 AM to 3:30 PM. Late morning flights often offer great lighting over the lagoon. (We discuss best times in detail later.)
Weather: The illusion is best seen under sunny, clear conditions. If the weather is poor (heavy clouds or rain), tours may reschedule or cancel. Note that if you fly and the waterfall isn’t visible that day due to weather, typically no refunds are given for just lack of visibility– so pick a clear day if possible.
What to bring: Don’t forget your camera! You’ll want to capture the view. Cameras and phones are allowed (make sure they’re secure with a strap or grip). Also wear your seatbelt and follow pilot instructions for safety.
Flight safety: All helicopter tours have professional pilots and adhere to strict safety checks. You’ll get a briefing before takeoff. Headsets are provided so you can hear commentary or ask questions in flight. If you’re prone to motion sickness, a helicopter is generally smooth, but consider medication if needed just in case.
A helicopter tour above Le Morne truly is the most dramatic way to experience the underwater waterfall. Many visitors say this was the highlight of their Mauritius trip. Next, we’ll look at an alternative that’s just as exciting: seeing the waterfall by seaplane.
Seaplane Flights: Soar Over the Underwater Waterfall by Seaplane
If a helicopter ride is not your style or you’re looking for a different kind of adventure, consider a seaplane flight to witness the underwater waterfall. Seaplanes (often lightweight amphibious aircraft or microlights with floats) offer scenic flights from the water and are a popular option in Mauritius for sightseeing. In fact, some say the best way to see the underwater waterfall is by seaplane, as these planes can fly lower and slower for a prolonged view.
How Seaplane Tours Work: In Mauritius, seaplane tours typically operate from the calm lagoons of the southwest. One of the main departure points is La Prairie Beach (near Le Morne). You’ll meet your pilot at the lagoon, do a safety briefing, then board a small two-seater seaplane (one pilot, one passenger). With a dramatic water take-off, the plane skims the waves and ascends over the ocean. Within minutes you’ll be over the famous Underwater Waterfall – the pilot will circle or zigzag to give you the best angles of the illusion. Most seaplane flights are private (just you and the pilot), making it an intimate experience. Couples can opt for “duo flights” where two seaplanes fly side by side, one person in each plane, so you share the experience together at the same time.
Flight Durations and Routes: Seaplane tour packages come in various lengths to suit your budget and sightseeing desires:
15-minute Flight – Underwater Waterfall Only: A quick up-and-down flight focusing on the Le Morne underwater waterfall illusion. You’ll take off, fly directly over the waterfall for a few passes (enjoying close-up views of the swirling sands and reef), and land back in the lagoon. Ideal if you just want to tick off the waterfall from your list or are short on time.
25-minute Flight – Waterfall + Extended Lagoon Tour: In addition to the waterfall, the pilot will give you an extended aerial tour of the southwest lagoon. You might fly along the coast to see sights like Ilot Fourneau, Crystal Rock, or the edge of the Black River Gorges area, before returning. This option provides a bit more airtime to soak in the scenery.
40-minute Flight – Popular Option: A longer journey that covers the underwater waterfall plus a wider loop over Mauritius’ southern coastline. Often this includes flying around Le Morne Mountain (the UNESCO site) for a unique view of its cliffs, and over Baie du Cap or Bel Ombre lagoons. You get a comprehensive tour of the region’s beauty from above.
80-minute Flight – Ultimate Aerial Tour: An hour+ epic flight covering all of the above and more. For example, some 80-min routes will take you from Le Morne all the way to Blue Bay Marine Park in the southeast and back, essentially showcasing the entire coastline, coral reefs, and maybe even sights like Ile aux Cerfs if arranged. This is the most expensive but gives you the full package of aerial views in one go.
All flights, of course, include multiple passes over the underwater waterfall to admire it from different angles. The 360° panoramic view from the seaplane’s bubble canopy is fantastic for photography – you can capture the vivid colors and patterns of the lagoon easily.
Seaplane Tour Prices: Prices vary by duration. As a guideline (per recent rates):
15 min Experience: ~€169 per person (private 1 pax).
25 min Discovery: ~€225 per person.
40 min Privilege: ~€329 per person.
80 min Excellence: ~€565 per person.
These are for a single-passenger flight (exclusive plane just for you). If two people want to fly at the same time, you’d opt for the Duo option, which essentially costs roughly double (since it uses two planes). For example, a 15-min duo flight for two people is around €375 total, and a 40-min duo is about €695 total. Some operators may quote in Mauritian Rupees, but we’ve given Euro estimates for easy reference. Always check the latest prices with the provider as they can change with season or fuel costs.
Seaplane Operators: LagoonFLIGHT is a leading seaplane tour operator in Mauritius, known for daily flights over the underwater waterfall. They operate from La Prairie and have highly experienced pilots (with great reviews from travelers). Another operator is sometimes offered via hotel activity desks or companies like Island Wings. All must follow strict civil aviation rules. Only one passenger flies per plane for safety (max weight ~100kg and height ~2m restrictions often apply), so these are truly personal flights. This means if you have a family or group, you’d fly one after another or do multiple planes. On the plus side, everyone gets a “window seat” – you’re right in the cockpit with the pilot, which is an amazing perspective!
The Seaplane Experience: People absolutely rave about it – not only do you see the underwater waterfall clearly (often the pilots will point it out and even bank the plane for a better look), but you also get the thrill of water take-off and landing. Imagine skimming across a turquoise lagoon, then suddenly you’re airborne over one of the most beautiful seascapes on Earth. It’s part thrill ride, part scenic tour. The open windows and the lower altitude give you a real sense of flying, unlike bigger planes. You might even spot dolphins or rays in the lagoon from above if you’re lucky.
Tips for Seaplane Tours:
Go in the morning: Calm winds and smooth water are more likely at sunrise and morning hours, which makes for easier take-off and better visibility. (Afternoon flights can be bumpier if wind picks up.)
Dress comfortably: It can be warm in the small plane, so light clothing is fine. Sunglasses help with glare. You’ll wear a headset to hear the pilot.
Camera/GoPro: Highly recommended to bring. The pilot can even slow down or circle for you to get that perfect shot of the underwater waterfall. Ensure your camera is secured (the cabin is open-air).
Book ahead: Because it’s one passenger at a time, slots are limited. Reserve your flight early in your trip. If you’re a couple wanting the duo experience, definitely book well in advance so they can allocate two aircraft.
Listen to the pilot: They will give safety instructions (e.g. weight balance, how to latch the canopy) and guide you on the sights. The pilots usually enjoy pointing out landmarks and explaining the phenomenon as you fly.
Weight/health restrictions: Check with the operator if you are over the weight/height limit or have any medical conditions. Pregnant women should consult a doctor and inform the pilot.
Overall, a seaplane flight over Mauritius’ underwater waterfall is a thrilling, unique way to experience this natural wonder. It’s a bit like a private rollercoaster with the most stunning view imaginable!
Now, what if you have a drone and want to capture the waterfall yourself? That’s our next topic, but with a word of caution.
Drone Viewing: Can You See the Underwater Waterfall by Drone? (Tips & Warnings)
For tech-savvy travelers, flying a drone over the lagoon might seem like a great way to get your own aerial view of the underwater waterfall. Indeed, some spectacular YouTube and Instagram videos of the Le Morne underwater waterfall were shot by drones. It is possible to see the illusion by drone, but it requires the right equipment, skills, and safety precautions. Here’s what you need to know before attempting it:
Distance and Visibility: The underwater waterfall illusion is not right off the beach – it lies a few kilometers out to sea from Le Morne. To capture it, you’ll likely need to fly your drone 1–2 km offshore from the nearest launch point (e.g. the beach by the RIU Le Morne/Turquoise resort or the public La Prairie beach). Most consumer drones (e.g. DJI models) have the range to go that far, but local regulations require you to keep your drone within line of sight. Realistically, at a kilometer out over the ocean, it’s very hard to see your drone, so you’d be pushing the boundaries of safe/legal operation. The signal can also weaken over that distance, especially if there are interference or strong winds.
Wind conditions: Le Morne is known as one of the world’s top kitesurfing spots – which tells you it’s often very windy. Strong gusts are common, especially in the afternoons or in July/August trade wind season. A drone can easily be blown off course or struggle to return against headwinds. Many drones have been lost to the sea here due to wind or battery running out on the way back. We strongly advise attempting drone flights only on calm days, typically early morning when winds are minimal.
Air traffic and kitesurfers: This area has a lot of activity in the air: not only your drone, but also dozens of kitesurfers who may be jumping and flying kite canopies up to 30m high, helicopters passing through on waterfall tours, and seaplanes taking off. This creates a very risky environment for drone operation. Never fly your drone near kite surfers – you could entangle in a kite line and cause an accident (as well as destroy your drone). Keep well away from the kite lagoon (usually marked by the group of kites closer to shore). Also, maintain a low altitude (under 60-70m) until you’re far offshore, and do not ascend to heights where helicopters may be flying. Tour helicopters often fly between 150m to 300m altitude over the lagoon; a collision with a drone would be extremely dangerous. It’s best to launch and get out over the ocean when no aircraft are in sight or hearing range, and stay below 120m (400ft) at all times (which is a common legal limit).
Drone Law in Mauritius: As of this writing, hobby drones under a certain weight can be flown for personal use, but you should avoid restricted zones (e.g. near airports, military bases, or national parks). Le Morne peninsula is not in a no-fly zone by default, but always double-check current regulations. It’s wise to inform any nearby hotel security or authorities if you plan to fly, just so they are aware (they might advise on any local rules). Flying over crowds or private property (like resort areas with guests) should be avoided for privacy and safety.
Tips for Capturing the Underwater Waterfall by Drone:
Launch from a clear, open area: The beach near Hotel Riu Creole/Turquoise is a common spot to launch, as it’s closest to the waterfall and already open to the ocean. Ensure no people or kites are immediately around when you take off.
Use a high-quality drone: You’ll need a drone with a good camera to truly capture the color contrast, and strong GPS stability to handle any wind. A drone with 4K camera and good range (e.g. DJI Mavic series or Phantom) is recommended.
Plan your route: Point your drone towards the reef drop-off (you can identify the change in water color from turquoise to deep blue). It may help to use Google Maps satellite view beforehand to gauge the distance and orientation of the “waterfall” from your launch point.
Fly high enough for perspective: To see the waterfall effect, you should fly at least ~100 meters high when over the site. The illusion is visible from above looking down at the reef edge. Some pilots go up to 200-300m for a wider view, but remember to stay within legal altitude limits.
Watch battery and Return Early: Ocean wind and long distance will drain your drone’s battery faster than usual. Be very conservative – start coming back once you’ve used ~40% of your battery, to be safe. You do not want your drone auto-landing out at sea.
Morning flights are safer: As mentioned, early morning typically has fewer people around, no active kitesurfers (they usually start later when wind picks up), and no tour flights yet (helicopter/seaplane tours often begin around 9-10 AM). The light in morning can also be nice for contrast. Avoid late afternoon because you might also get glare from the sun lower in the sky or even the mountain’s shadow creeping over the lagoon.
Stay aware: Continuously scan the sky yourself (have a friend act as a spotter if possible) to watch for any approaching helicopter or plane. If you hear or see one, immediately descend and/or move away to a safe area – give them plenty of space.
Be prepared to lose the drone: This sounds pessimistic, but you should be mentally prepared that things can go wrong – whether sudden wind, bird attack (seabirds have been known to harass drones), or technical glitch. Don’t fly a drone you aren’t willing to part with. Consider getting drone insurance if available.
In summary, can you see the Mauritius underwater waterfall by drone? Yes – some travelers have done it and gotten amazing footage. But should you? Only if you are very confident in your drone flying skills and take all precautions. The risks (to your drone and to others) are not negligible. If you do attempt it, follow the guidelines above meticulously. Otherwise, you might find it more enjoyable to book a helicopter or seaplane ride where you can relax and let the professionals handle the flying, while you simply enjoy the view and snap photos in comfort.
(Safety reminder: The airspace around Le Morne is shared by tour aircraft and hobbyists. Always prioritize safety – a scenic view is not worth endangering anyone.)
Best Time to Visit the Underwater Waterfall (Season & Time of Day)
One of the most common questions is “when is the best time to see the underwater waterfall?” Timing can indeed affect how clearly you see the illusion. Let’s break it down into time of year and time of day:
Best Time of Year:
Mauritius is a year-round destination, and the underwater waterfall can be visible in any season if conditions are right. However, weather patterns do influence your experience. Generally, the dry cooler months from May to early December are considered the optimal period to witness the waterfall at its clearest. During these months (late autumn, winter, and spring in Mauritius), the weather is typically sunny, with fewer rain showers and less humidity. The skies tend to be clearer and the ocean water clarity is excellent – all contributing to a sharp, vibrant view of the undersea contours.
Within that range, many travel experts specifically recommend September through November as an ideal window. This is end of the Mauritian winter and spring: the winds are moderate, rainfall is low, and it’s before the hottest months. By mid-summer (December through March), Mauritius enters its rainy season – it becomes hotter, more humid and there’s a higher chance of cloud cover or afternoon thunderstorms. Also, cyclone season runs January to March. While direct hits are rare, tropical disturbances can bring cloudy skies for days. If you visit in those summer months, just watch the weather forecasts and try to go on a clear day between rains.
Another consideration: whale watching season off Le Morne is June to November (for humpback whales). If you go during those months, there’s a small bonus chance you could spot whales from the air on your flight!
To sum up, plan your underwater waterfall excursion in Mauritius’ drier months if you can, particularly Sept–Dec for the best odds of perfect visibility. But if you’re there outside that period and catch a sunny day, go for it – the illusion is waiting whenever the water is clear and sun is out.
Best Time of Day:
The underwater waterfall illusion is created by contrasts in water color, which means lighting is key. The consensus is that mid-morning to around midday offers the clearest view. Around 10:00–12:00 the sun is high enough to light up the shallow lagoon brilliantly, but not directly overhead to wash out the relief. This angled sunlight helps accentuate the difference between the glowing turquoise (shallow) and the dark blue (deep) areas, making the “waterfall” stand out.
If you go too early (just after sunrise), the sun might be a bit low, casting longer shadows and the lagoon might appear darker or the colors less intense. On the other hand, in late afternoon, the sun starts sinking to the west – which in Mauritius means it could be facing you (causing glare) if you’re looking from the east side, or even start to set behind Le Morne Mountain by early evening. The mountain could cast a shadow on the lagoon in late afternoon hours, potentially dulling the waterfall effect. Also, clouds are more likely to develop in the afternoon due to daytime heating, whereas mornings are often clearer.
For these reasons, aim for morning hours if possible. Many helicopter/seaplane operators will recommend morning flights for best experience. One travel tip suggests that around 11 AM is perfect, and indeed some visitors who flew at noon reported excellent views. If morning slots are full, early afternoon (12–2 PM) can still be fine as long as it’s a clear day – just be mindful of that overhead sun at its zenith around 12–1 PM which can make everything uniformly bright. Even then, the contrast of the sand flowing should be visible, especially to the camera if you use a polarizing filter to cut through any glare.
Other factors: Try to schedule your flight at a low tide if it coincides with good timing. At lower tide, more of the sandbanks are closer to the surface, potentially making water color differences more pronounced. It’s a minor factor, but some pilots mention it. However, do not worry too much about tides – clarity of water and sun matters more.
Also, consider wind patterns: Mornings not only have less wind, but also the sea surface is calmer. A glassy calm sea gives a clearer “window” into the water. If it’s very windy, the surface can ripple and reflect light, slightly reducing how clearly you see through the water from above. So again, calm mornings win out.
Bottom line: The best time of day to see the Mauritius underwater waterfall illusion is mid-morning under a clear, sunny sky, ideally during the drier months of the year. This combination will give you the brightest turquoise hues and starkest contrast for that perfect postcard view. If you have some flexibility in your schedule, keep an eye on the weather and pounce on a clear morning to book your flight.
Getting There: Transport Tips for Your Underwater Waterfall Adventure
Now that you know how to see the underwater waterfall, the next question is: how do you get to the starting point of the tour? Le Morne peninsula is in the southwest corner of Mauritius, and whether you’re catching a helicopter or a seaplane, you’ll need to arrange transportation to the departure location. Here we’ll cover local transport options and how our private transfer service can help make your trip smooth and easy.
Helicopter Tour Departures: If your helicopter flight is departing from SSR International Airport (Mahébourg), and you are not already near the airport, you’ll have to travel there. The airport is about 60 km (about an hour’s drive) from the main tourist hubs in the north and about 40–50 km from Flic en Flac or Grand Baie. Many travelers book helicopter tours as part of an excursion, which may include road transfers. Check if your tour package includes pick-up; some luxury hotel concierge services will arrange a car to the helipad for you. If not, you can book a taxi or private driver to take you to the airport or designated helipad. For example, if your flight departs from Le Paradis Hotel helipad in Le Morne (common for tours in that area), you’ll need to get yourself to that resort’s helipad entrance. This is where a reliable local transfer is invaluable – driving in Mauritius can be confusing for newcomers, and helipads aren’t always easy to find on your own.
Seaplane Departure (La Prairie): Seaplane flights over the underwater waterfall usually take off from La Prairie beach, a public beach on the south-western coast near Le Morne. This area is somewhat remote – there’s no big town immediately nearby. You’ll definitely need a car or driver to get there. Parking is limited and the road signage might not clearly indicate where the seaplane launch point is. By using a professional driver familiar with the area, you won’t waste time searching for the spot. They can drop you right where you meet your pilot. Additionally, if you’re staying at a resort elsewhere on the island (east coast, north, etc.), the drive to Le Morne can be 1 to 1.5 hours. Having a comfortable, air-conditioned vehicle and an experienced local driver can make that journey much more pleasant – and ensure you arrive on time for your flight slot.
Hiking Le Morne or Other Viewing: Perhaps you plan to hike up Le Morne Brabant to get a bird’s-eye view on foot. The trailhead is located in the Le Morne Brabant parking area behind the peninsula (accessible via a side road from Le Morne village). There is no public transportation that goes directly to the trail start; you must go by car or taxi. Likewise, if you just want to visit the Le Morne beaches (like the public beach near Riu or Paradis) to fly a drone or sightsee, you’ll need to drive. Taxis are not readily waiting in that remote area unless arranged.
Public Transport: Mauritius does have buses, but they won’t be practical for reaching at specific times for tours. Bus routes might get you to nearby villages, but not directly to an airport or secluded beach at the right hour. So we generally advise against relying on public buses for this particular trip.
Private Taxi/Transfer Service – Your Easiest Option
For maximum convenience and peace of mind, using a private transfer service is the best way to get to and from your underwater waterfall experience. With a private car and driver, you get door-to-door service on your schedule, no hassle.
Barefoot Transfers Mauritius (that’s us!) specializes in exactly these kinds of transfers for tourists. We provide airport pickups, hotel transfers, and custom trip transport anywhere on the island. Here’s how we can help make your underwater waterfall trip seamless:
Airport to Helipad Transfers: If you’re coming straight from SSR Airport to go on a helicopter tour (some travelers do this upon arrival or just before departure), we offer airport transfer by private car directly to the helipad or to your hotel first. For instance, if you plan an underwater waterfall flight on the same day you land, we can pick you up at arrivals, handle your luggage, and drive you promptly to the helicopter base (the airport’s own heli lounge or another site) on time for your flight. No need to navigate or rent a car after a long flight – just relax and let us get you there.
Hotel to Helipad/Seaplane Base: Wherever you are staying – be it a resort in Belle Mare, a villa in Grand Baie, or a hotel in Flic en Flac – we can pick you up at your doorstep and drive you to the southwest for your tour. Our drivers know all the common departure points (we’ve taken many clients to La Prairie beach for seaplanes and to Le Morne helipads). We’ll plan the route to avoid traffic and ensure timely arrival. If you’re unsure of what to do with your belongings, our driver can wait and keep the car secure during your flight, then bring you back afterward.
Round-trip Convenience: Typically, we arrange round-trip transfers, meaning the driver waits or returns to collect you after your activity. For example, if your helicopter tour is at 11:00 AM from Le Morne and lasts 15 minutes, the driver will be there to bring you back as soon as you’re done, perhaps even suggest a nice lunch spot if you want to celebrate the experience! You won’t have to worry about finding a taxi in a remote area or driving back on unfamiliar roads.
Local Knowledge and Comfort: All our vehicles are clean, comfortable, and air-conditioned – crucial for Mauritius’ warm climate. Our friendly drivers speak English and French, and they’re locals who know a lot about the island. Feel free to ask questions or get tips during your ride. They can also help coordinate with tour staff if needed (for instance, helping you check in for your flight or finding the exact meeting point).
Affordable and Reliable: We offer flat rate transfers with no hidden fees. When comparing the cost and convenience of a private transfer to renting a car for a day (plus fuel, insurance, navigation stress), many travelers find it well worth it. You get a personal chauffeur experience without the luxury price tag. And because we focus on airport and tour transfers, our team is used to meeting schedules – reliability is our pride. We understand that if we’re late, you could miss a once-in-a-lifetime tour, so we are always punctual (usually early)!
In short, using our private taxi service means you can focus 100% on enjoying the underwater waterfall excursion, without any logistical worries. We take care of the transportation from start to finish.
👉 Pro tip: If you have additional sightseeing in mind on the same day (say you want to visit Chamarel or the Seven Colored Earth after your flight), we can arrange a custom itinerary. Your driver can take you to those spots after the waterfall tour, turning it into a full-day adventure in the Le Morne area. Just let us know your plans, and we’ll accommodate.
Now, let’s answer some frequently asked questions you might have about the Mauritius underwater waterfall:
Mauritius Underwater Waterfall FAQ
Is the Mauritius underwater waterfall real?
The underwater waterfall is real as an optical illusion, but it’s not actually water falling underwater. It’s an effect created by sand and silt sliding down a steep drop-off in the ocean floor. From above, it truly looks like a giant waterfall inside the ocean, but if you go swimming or diving there, you won’t see a “waterfall” – just different water depths. Rest assured, it’s a natural phenomenon (not man-made), but it only looks like a waterfall from a bird’s-eye view.
Where is the underwater waterfall in Mauritius located?
It is located off the southwest coast of Mauritius, near Le Morne Brabant Peninsula. Specifically, it lies just beyond the barrier reef that encircles the lagoon at Le Morne. The exact spot is off the southern tip of the peninsula. Le Morne Mountain (a UNESCO World Heritage site) is the closest landmark on land. You can actually see the general area from Le Morne beach – it’s roughly in the direction where the lagoon’s turquoise color meets the deep ocean blue.
How can I see the Mauritius underwater waterfall?
The only way to see the full underwater waterfall illusion is from above, either by taking a helicopter tour or a seaplane flight over it. These flights will get you directly overhead for the best view. Alternatively, if you have a drone, you could fly it offshore to capture the view (with caution). A partial view is possible by hiking Le Morne Mountain – from the 500m summit you can glimpse the underwater patterns in good conditions, but it’s distant and not as vivid. You cannot see it from a glass-bottom boat or by snorkeling; from sea level the effect disappears. So to sum up: look for a flight (heli or seaplane) for a guaranteed and unforgettable viewing.
What is the best way to see the underwater waterfall – helicopter, seaplane, or other?
Both helicopter and seaplane tours are fantastic ways to see the underwater waterfall, and each has its pros. A helicopter offers a stable platform, can carry a couple or family together, and usually covers more sights in one flight (waterfall plus other landscapes). It’s great for photographers and those who want a slightly higher vantage point. A seaplane offers a more adventurous, intimate experience (one passenger per plane, low altitude, water takeoff/landing) which some find even more thrilling. The seaplane can fly lower for a closer look directly down into the lagoon. There is no single “best” – it depends on your preference. Helicopters might edge out for convenience (more departure locations, group capacity), whereas seaplanes win for novelty and close-up charm. Either way, from the air is the best. Hiking up Le Morne is a secondary option if you cannot fly, but you won’t get the full effect. Drones can show it too, but then you’re watching on a screen rather than with your own eyes. So we’d rank: 1) Helicopter/Seaplane (tie) as best, 2) drone (if you’re an enthusiast), 3) mountain hike (for a faint view plus the fun of hiking).
How much does it cost to see the underwater waterfall in Mauritius?
It depends on the method:
Helicopter Tour: Approximately €250–€400 per person for a shared 15-25 minute flight, or about €1200–€1600 for a private helicopter (4-5 seats). There are shorter private flights from nearby helipads around €1000+ as well (split among passengers). Some operators list around MUR 13,000 (~USD $300) per seat on a longer shared tour.
Seaplane Flight: Roughly €169 for a 15-minute solo flight, €225 for 25 min, €329 for 40 min, up to €565 for the 80-min extended tour. (Prices are per person, since it’s one person per plane at a time.)
Drone: If you already own a drone, seeing it by drone is basically free (aside from the cost of your equipment). There are no tickets for this of course, but do factor in the risk of losing a drone!
Hiking Le Morne: Free (just the cost of a guide if you hire one, which is recommended for safety on the hike, typically around €50 for a group). However, again, the view won’t be as striking as from a flight.
Transfers: Also consider transport costs – getting to the helipad or seaplane base might involve taxi fare. A private round-trip transfer might cost on the order of €60–€100 depending on distance (many tours will quote that separately if not included).
When budgeting, remember that these flights, while pricey, are truly a once-in-a-lifetime experience. Many travelers say it was worth the cost for the memories and photos. If you’re a bit flexible, look out for any special deals or group packages – sometimes booking via a local agency or with a group can lower the per-person price. But in general, expect a few hundred Euros per person for an aerial tour.

Can I just go by boat to see the underwater waterfall?
No – you cannot see the illusion from a boat. From the sea level perspective, the water all blends together and you won’t perceive the waterfall effect at all. Some people imagine there might be a glass-bottom boat or submarine ride to see it, but that wouldn’t work because it’s an optical illusion dependent on looking from above. You can take boat trips around Le Morne (for example, sightseeing or snorkeling trips in the lagoon), but you’ll just see beautiful water and reef, nothing that looks like a waterfall. Even scuba divers who dive near the drop-off just see a normal deep wall and currents, not anything like an “underwater fall.” So, save the boat trips for dolphin watching or snorkeling; for the waterfall, stick to the air.
Is it safe to swim or surf over the underwater waterfall?
Yes – completely safe. The area above the so-called waterfall is a normal lagoon with normal ocean currents. In fact, the famous One Eye surf spot is right at Le Morne’s reef, very close by, and surfers/kitesurfers ride those waters daily. Swimmers and snorkelers enjoy the lagoon too. There’s no actual drop that will suck you down; the “fall” is a gradual flow of sand under the water. Of course, if you swim out to the edge of the reef where the shelf drops off 4,000m, you’ll suddenly be in very deep ocean – but you won’t get pulled down into it like a drain or anything! Just be mindful of waves at the reef break and don’t go beyond safe swimming zones if you’re not experienced with open ocean. But generally, being on the surface above the site is no different than any other spot in the lagoon. Many people kiteboard right over it without even realizing what’s below.
Can I fly a drone to get a view of the underwater waterfall?
Technically, yes you can fly a drone from shore to see the underwater waterfall from above, and some people have done so. However, it comes with risks (and potentially legal considerations). If you’re an experienced drone pilot, you could launch from the Le Morne public beach or boat park, and fly out towards the reef drop-off. You’d need a drone with good range and stable in wind (DJI Mavic 2/3, Phantom, etc.). The distance is around 1.5 – 2 km out. You also must keep clear of kitesurfers and watch for helicopter traffic. It’s crucial to fly early morning with low wind and fewer kites in the air. The drone’s live feed should show the dramatic colors once you’re overhead – you can take video or photos and return. Do not exceed altitude limits (stay under 120m) and keep line of sight if possible (though it will be tiny at that distance). Many advise against doing this unless you are very confident, because lost drones aren’t uncommon. If you decide to try, follow the safety tips we outlined in the Drone section above. Always yield right of way to any aircraft and avoid busy times. Done responsibly, a drone can indeed capture the waterfall illusion – but weigh the cost of possibly losing your device versus the cost of just taking a tour. For casual travelers, booking a flight is the safer and more guaranteed method.
When is the best time of day to see the underwater waterfall?
Try to go in the morning, around 10-11 AM for optimal viewing. Mid-morning light brings out the contrast in the water colors vividly. The sun is not too low and not straight overhead – a perfect angle to illuminate the shallow sand and create a dark shadow in the deep, enhancing the “fall” effect. Late morning typically has clear skies before any small clouds develop. Flights around noon can also be good (many have had great views at 12 or even 1 PM). Just avoid very early (dawn’s low angle light) or late afternoon (possible glare or shadows). If your schedule only allows afternoon, aim for early afternoon by 2-3 PM at the latest, and make sure it’s a clear sunny day.
What’s the best time of year to visit the underwater waterfall?
The Mauritian winter and spring months are best – roughly May through November. This period has the most stable weather: sunny, less rainfall, and good visibility. In particular, September, October, November are often recommended as ideal months. During these months, you have a high chance of clear skies and the lagoon water is very clear (little runoff or plankton). December can also be great early in the month before the peak of summer heat and humidity. Conversely, the cyclone/rainy season (Jan–Mar) can be hit or miss – you might get lucky with a clear day, but there’s a higher chance of clouds or cancellation due to storms. April is a shoulder month that can have nice weather as well. Essentially, plan for the dry season if you can, and you’ll maximize your odds of a perfect view. But remember, the phenomenon is there all year; just pick a sunny day and you’ll see it.
Can you hike Le Morne Brabant to see the underwater waterfall?
You can hike Le Morne (highly recommended for its own sake – the views are stunning), and from the summit you get a panoramic overlook of the lagoons. On a clear day, you may discern the lighter vs darker patches where the underwater waterfall is. However, it will appear as a subtle coloration difference, not the dramatic vertical drop illusion you see in aerial photos. So yes, you can see “something” of the underwater waterfall from the top of Le Morne, but it’s not the full experience. If you’re an avid hiker or don’t want to spend on a flight, it’s worth doing. The hike is medium difficulty, takes about 3-4 hours round trip, and you should go with a guide or group for safety (the last section is steep). Reach the top by early morning for clear views (and avoid midday heat). Enjoy the amazing scenery – you’ll see all of Le Morne’s reef, the turquoise lagoon, and you can point out roughly where the sand is flowing underwater. Some hikers combine this with later doing a helicopter tour to then see up-close what they spotted from the peak.
Why does Mauritius have an underwater waterfall illusion?
It’s all about the unique geology of Mauritius. The island sits on a relatively shallow underwater platform that extends out from the coast. At Le Morne, the edge of this platform is very steep – imagine a cliff at the bottom of the sea. Over time, sand from the beaches and silt from the reefs get pulled by currents towards that edge. Where the plateau drops off, the sand on the ocean floor essentially “falls” down the slope into the deeper ocean. This movement creates a plume-like shape under the water. Because the shallow lagoon water is a light turquoise and the deep ocean water below the drop-off is a deep blue, when you look from above it contrasts sharply – giving the appearance of a waterfall’s white froth and a pool beneath. It’s basically an optical trick of color and depth. The reason Mauritius is one of the few places with this effect is the combination of clear water, white sand, and a dramatic drop-off so close to shore. It’s a confluence of natural factors that turned into a spectacular illusion!
Is the underwater waterfall a UNESCO site or protected?
The underwater waterfall itself is not an official UNESCO site (as it’s not a tangible cultural or natural heritage site in the usual sense – it’s more of a visual phenomenon). However, Le Morne Brabant Mountain right next to it is a UNESCO World Heritage Site (for its historical significance as a refuge for escaped slaves in the 19th century). The lagoon and reef fall under marine conservation regulations of Mauritius. The area is within a lagoon that is environmentally sensitive, so activities like fishing are regulated. When you take a helicopter or seaplane, you’re obviously not disturbing it. If you were to go diving or boating, normal marine park rules apply (don’t damage coral, etc.). In essence, there’s no direct special protection just for the “waterfall” illusion, but it falls within Mauritius’ efforts to protect coral reefs and their environment. Always practice reef-safe behavior (e.g., if snorkeling nearby, don’t touch corals, etc.).
With those FAQs covered, you should have a clear picture of what the Mauritius underwater waterfall is and how to experience it. All that’s left is to see it for yourself!
