Trou d’Eau Douce: 5 Island Adventure with BBQ & Snorkeling

Speed, sea, and a beachside feast. This six-hour trip packs Mauritius’s southeast coast into one lively outing, with a fast boat, island stops, snorkeling, a BBQ lunch, and chances to spot dolphins, turtles, and monkeys. I especially like the mix of colonial history and sea time, plus the small group limit of 14 people. The main trade-off is that the schedule is busy, so the quieter islands can feel like brief photo stops rather than places to explore slowly.

I also like the strong value at $100 per person. Lunch, drinks, snacks, snorkeling equipment, and the main stops are included, while the guide handles the route and keeps the group moving. Just know that this is a speedboat trip, not a relaxing catamaran cruise, and the ride can be lively on open water.

Five useful things to know before you go

• The boat is a speedboat: One booking guest expected a catamaran, but found the speedboat more exciting. Expect wind, spray, quick turns, and a thrilling ride.
• The small group matters: With no more than 14 people, you get a better chance of hearing the French and English-speaking guide and getting help in the water.
• Wildlife sightings are possible, not promised: Dolphins, turtles, monkeys, flying foxes, barracuda, and sea birds have all been seen, but nature sets the timetable.
• The first islands are more about scenery and history: Ile aux Fouquets and Ile de la Passe offer striking views and an old lighthouse, but they are rocky and not long beach stops.
• Bring water shoes if you have them: One detailed account found the early island stops stony, and several people wished the snorkeling gear were better.
• Lunch is a real part of the experience: The beach BBQ includes drinks, beer, and local rum, with vegetarian food available on request.

Setting out from Trou d’Eau Douce

You meet at the jetty beside the Mauritius flag, near Blue Alizé Catamaran Ile aux Cerfs. Despite the meeting-point name, this experience uses a speedboat, and that distinction matters. You are not settling into a broad, slow sailing boat for the day. You are moving quickly between islands, with the ride itself forming a large part of the fun.

The tour lasts about six hours. That is enough time for a varied route, but not enough for long walks at every stop. The schedule works best if you see it as a sampler of the southeast: a little history, a little wildlife, swimming, snorkeling, a waterfall, and a long lunch break on Ile aux Cerfs.

The group limit of 14 is a helpful feature. A guide can speak with people more easily, assist with boarding, and help with photos. Guides named in feedback include Rajiv, Rajesh, Oliver, Wendel, Jeremy, Ranjeev, Tony, and Rhaiv. The experience can vary with the individual guide, but the strongest accounts describe guides who keep the mood light, explain the route, and look after solo passengers and families.

Bring sunglasses, a sun hat, sunscreen, and a towel. Leave large bags and luggage behind. The boat has limited room, and this is not the outing for hauling beach equipment or a suitcase.

Ile aux Cerfs: a famous first taste

Ile aux Cerfs is one of Mauritius’s best-known beach islands, and it gives you an early look at the pale sand and clear water that attract people to the east coast. You get about 40 minutes for a walk, sightseeing, and free time.

This is a pleasant introduction, but do not expect a secluded island all to yourself. Ile aux Cerfs is popular, and the stop is fairly short. You can take photographs, walk along the beach, or get in the water, but you will need to choose rather than do everything at length.

The island returns later in the day for the main meal and a longer beach break. That second visit is more important. It gives you about two hours to eat, swim, sunbathe, and relax after the faster sightseeing portion of the route.

Grande River South East Waterfall and the monkeys

The boat heads to the Grande River South East waterfall, usually for around 20 minutes. The waterfall itself may not impress everyone equally. It is attractive, but several detailed accounts suggest that the surrounding wildlife can be more memorable than the cascade.

Look toward the trees and riverbanks for monkeys. Guides have sometimes brought the boat close enough for good views, and a few people have seen monkeys approach the boat. That makes for entertaining photographs, but I would avoid feeding them even if other boats do. Feeding wild animals can change their behavior and create problems for the animals and future visitors.

This stop is mainly a photo visit, so do not expect a long walk to a viewing platform or a full nature outing. It works well as a quick break from the boat and a chance to see a different side of the southeast coast.

Snorkeling in the Grand Port area

The swimming and snorkeling stop lasts about 40 minutes in the Grand Port district. This is one of the strongest parts of the day if you enjoy being in the water. The lagoon can be calm and clear, with fish and other marine life visible below the surface.

The contrast around the offshore islands is especially striking. On the sheltered side, the water can look turquoise and still. Around the outer side, Indian Ocean waves hit the reef and breakers with much more force. The boat lets you see both moods in a short span.

Snorkeling equipment is included, which helps keep the cost down. Still, equipment quality appears to vary. If you own a mask and snorkel, bringing them is sensible for comfort and hygiene. Aqua shoes are also useful for rocky entries and island shorelines.

Sea turtles have been seen during the snorkeling stop, and one account described swimming near a turtle for about ten minutes. That is a lucky encounter, not a scheduled part of the activity. The same applies to dolphins. You might see them near the boat, but the crew cannot guarantee a sighting.

Fouquets Island and the old lighthouse

The route includes Fouquets Island, also called Ile aux Fouquets, where you stop near the old lighthouse. The island visit lasts about 20 minutes, with time for photos and a short walk.

The lighthouse is more than a pretty backdrop. It is over 200 years old and has been declared a historic monument. The island also connects to the naval Battle of Grand Port in 1810, fought between French and British forces. It is remembered as the only victory of the Napoleonic Navy and is listed on the Arc de Triomphe in Paris.

That context gives the stop more weight than a simple island photo break. You are looking at a small piece of Mauritius’s colonial-era past in the same waters where a major naval conflict took place. The drawback is time. Twenty minutes will give you a look and some photographs, but not a long history lesson or a thorough island walk.

The guide’s explanations can make a big difference here. Guides such as Rajiv, Rajesh, Oliver, and Wendel received praise for adding humor and useful information, while one positive account wished the guide had explained more of what the group was seeing. If history matters to you, ask questions during the stop.

Ile de la Passe and the rough side of the sea

Ile de la Passe is mainly a sightseeing pass-by rather than a long landing. It forms part of the same historic story as Ile aux Fouquets and helps show why this stretch of water mattered during the Battle of Grand Port.

The boat route also gives you a strong visual contrast between the calm lagoon and the exposed ocean. One side can feel almost pool-like, while the other takes the full force of the Indian Ocean. This is one of the best reasons to choose a speedboat instead of staying at one beach all day.

If you are prone to motion sickness, sit where the boat feels most stable, keep your eyes on the horizon, and take the ride seriously. The open-water sections can be windy and bumpy. For thrill seekers, that is a highlight. For anyone expecting a gentle cruise, it may be the day’s biggest surprise.

Wildlife watching around the islands

The wildlife is a happy extra rather than a fixed show. Depending on conditions and the crew’s skill, you might see dolphins, sea turtles, monkeys, flying foxes, barracuda, and sea birds.

Several guides have been praised for spotting animals and making another attempt when the first search came up empty. One guide returned to look for dolphins a second time, and the group eventually found them. That kind of effort can turn an ordinary boat ride into the day’s best memory.

Still, keep expectations sensible. Dolphins move freely, turtles surface when they choose, and monkeys are wild animals. A responsible guide should avoid crowding animals, and you should be cautious about any close approach. One account specifically appreciated a guide who kept a more respectful distance from dolphins and turtles, while also raising concerns about boats feeding monkeys and birds for photographs.

Ile aux Aigrettes: a swim and a drink

Ile aux Aigrettes provides another water stop, with about 45 minutes for swimming and an aperitif. By this point, you have already had history, a waterfall, and a snorkeling session, so this stop feels less like sightseeing and more like a chance to cool off.

The swimming time is valuable because the itinerary moves quickly. You can get back in the water without giving up a major landmark. Drinks and snacks are part of the package, and the crew may serve the local drink often called Mauritian coffee, along with rum-based drinks.

Alcohol is available during the day, including beer and local rum. Enjoy it carefully, especially before swimming or if the sea is rough. Nonalcoholic choices are important too, and you can ask the crew what is available.

BBQ lunch and two hours on Ile aux Cerfs

The final long stop returns you to Ile aux Cerfs for lunch. You get about two hours for a beachside BBQ, drinks, and free time.

The meal is one of the most praised parts of the outing. Expect a straightforward island BBQ rather than fine dining, but the food is described as tasty and satisfying. Vegetarian meals have been provided, including for a group of four vegans, so tell the operator about dietary needs when booking or before departure.

Beer and other drinks are included, along with the local rum service. Some accounts also mention the option to pay extra for lobster, but that is not part of the stated $100 package, so confirm the price before agreeing to it.

After lunch, the island gives you the slowest part of the day. Swim in the clear water, walk on the sand, sunbathe, or simply sit down and let the boat ride catch up with you. This is where the trip shifts from active sightseeing to a proper beach break.

Is $100 good value?

At $100 per person, I consider this a strong package if you want variety. You receive a six-hour speedboat trip, a bilingual guide, lunch, drinks, snacks, snorkeling equipment, and visits to several notable coastal sites. A small group of up to 14 adds value because you are not lost in a large boat crowd.

The price is less attractive if your ideal day is a quiet beach, a long snorkel, or a slow historical visit. You are paying for range and convenience, not extended time at one location. Hotel pickup and drop-off are not included, so you need to arrange your own way to the Trou d’Eau Douce jetty.

The tour includes plenty, but not every extra. Large bags are not allowed, and pregnant women are advised not to take part. Free cancellation up to 24 hours before departure and reserve-now, pay-later booking make the commitment easier, according to the booking terms provided.

Who should book this boat trip?

I would choose this trip if you want to see many sides of Mauritius in one day and enjoy an energetic ride between stops. It suits couples, families with older children, solo visitors, and anyone who likes mixing water time with sightseeing.

It is particularly good for people who want a chance to see dolphins or turtles without booking a separate wildlife trip. Just remember that sightings are luck, not a promise. The strongest family accounts included an eight-year-old, but each child needs to be comfortable with speed, sun, boat movement, and swimming.

I would think twice if you dislike bumpy rides, need long quiet visits at historic sites, or want a polished catamaran cruise. This is a fast, social, active outing. The boat, guide, weather, and wildlife all shape the day.

Final booking advice

Book it if you want a packed southeast-coast sampler with excellent scenery, a good lunch, and a real chance of memorable wildlife sightings. The most useful preparation is simple: bring sunscreen, a towel, water shoes, and your own snorkeling gear if you have it. Keep your bag small, and expect the speedboat ride to be as much a feature as the islands.

I would not book it for a slow, private island escape. For most people who want to make one $100 excursion cover history, beaches, snorkeling, waterfalls, wildlife, and food, it is a very persuasive choice.
