Trou D’Eau Douce: 5 island tour Mauritius with lunch/drinks

The most striking part of this six-hour speedboat trip is the contrast between quiet lagoon water and the open Indian Ocean near Île aux Phares. You get beaches, a waterfall, a nature reserve, and old colonial battle sites in one compact day. I especially like the BBQ lunch on Île aux Cerfs and the chance to see the coast from a fast, open boat rather than a large catamaran.

I also like the mix of swimming and history. You can cool off at Île aux Aigrettes, watch the sea crash around the old lighthouse, and pass Île de la Passe, where a major 1810 naval battle took place. The main caution is space: one booking arrived to find a full speedboat with ten people already aboard, making the front seats tight and sun-exposed. Ask about group size before departure if comfort matters to you.

Key points to know before booking

• Six hours on the east coast: The route packs several islands, a waterfall, swimming, snorkeling, lunch, and drinks into one busy outing.
• Île aux Phares has real historical weight: Its lighthouse is more than 200 years old, and the island is linked to the 1810 naval battle of Grand Port.
• Lunch is served on Île aux Cerfs: Expect a beach BBQ, swimming time, and drinks, including local rum and soft drinks.
• The speedboat makes the route lively: You move quickly between sites, but seating can feel cramped when the boat is full.
• Lucas is one named guide: English and French tours are available, and the captain can shape the pace more closely on a private outing.
• Bring your own swim kit: Pack a towel, sunscreen, hat, sunglasses, swimwear, and goggles. The booking details are unclear about snorkeling equipment, so bringing your own is safest.

Why this east coast boat trip works

Mauritius is easy to admire from a beach, but the east coast makes more sense from the water. The lagoon is broad and bright, with low islands scattered between the mainland and the reef. A speedboat gives you a quick way to link those places without spending the day on one beach.

The route also has more range than a simple Île aux Cerfs transfer. You see a waterfall, old lighthouse, protected vegetation, a sandbank, and sites tied to French and British colonial conflict. It is not a slow nature study, and it is not a pure history tour. Instead, it is a fast-moving day that gives you several snapshots of Mauritius.

I would think of the trip as an active sightseeing day with plenty of swimming. You will spend time in the boat, often in direct sun, so this is better for people who like motion and variety than for anyone wanting a quiet, shaded cruise.

Setting out from Trou d’Eau Douce

The meeting point is at the end of the jetty beside the Mauritian flag, near Blue Alizé Catamaran Île aux Cerfs. That detail matters because the waterfront can have several boats and operators, so give yourself time to locate the correct departure point.

The first speedboat ride takes about 20 minutes. You will feel the pace immediately. An open speedboat is more exciting than a slow ferry, but it gives you less shelter from sun and spray. Wear swimwear under your clothes and keep anything valuable in a dry bag.

The boat is intended for a small group, but the actual feel depends on the day. A full boat can mean close seating, especially at the front where there may be no shade. If you want a quieter ride, ask whether a private departure is available. One party switched to a private tour within about ten minutes of arriving, and that choice allowed them to decide how long to stay at each stop. That flexibility can change the day from a packed schedule into a much more relaxed outing.

Île aux Cerfs, the main beach stop

Île aux Cerfs is the best-known stop and the visual centerpiece of the day. White sand, clear turquoise water, and a broad lagoon give you the classic Mauritius postcard scene. You get free time here early in the route, then return later for lunch and a longer swim.

The first visit helps you get your bearings. Walk along the beach, take photographs, or get into the water while the boat crew handles the next part of the route. The island is also associated with water sports, though this tour does not promise a particular paid activity, so do not book it expecting every possible beach attraction to be included.

The return visit lasts about two hours and includes the BBQ lunch. That longer stop is useful because it gives you time to eat without rushing straight back into the boat. It also gives you a second chance to swim after the morning sightseeing.

I like having Île aux Cerfs at both ends of the route. You see the famous beach before the day becomes busy with historic and natural sites, then finish with a proper meal and unhurried water time. The tradeoff is that this is the most popular place on the route, so it is not the spot to expect solitude.

The Grand River South East waterfall

The Grand River South East waterfall is a photo stop and sightseeing visit of about 20 minutes. It is reached from the water, which gives you a different view than a roadside lookout. The falls drop into the river mouth, surrounded by the steep green sides of the river valley.

Twenty minutes is enough for photographs and a quick look, but not for a long walk or extended exploration. Treat this as a scenic pause rather than a full waterfall excursion. You will want your camera ready before the boat arrives, since the stop is short.

This is one of the tour’s most worthwhile contrasts. After open sea and bright sand, the river feels cooler and more enclosed. It also breaks up the beach time, which keeps the day from becoming a string of similar swim stops.

Snorkeling in the Mauritian lagoon

The route allows about 40 minutes for snorkeling in Mauritius. Clear, shallow lagoon water can make this one of the most pleasant parts of the day, especially if you prefer a simple swim over a formal reef excursion.

There is an important practical wrinkle. The general description refers to snorkeling gear and guided sessions, but the specific inclusions list lunch and drinks only, while the exclusions say snorkeling gear and the snorkeling session are not included. Bring your own mask, snorkel, and goggles if you have them, and confirm the exact arrangement before boarding.

Do not assume this is a specialist marine tour. The supplied details promise time for snorkeling, but they do not specify particular fish, coral sites, or underwater species. I would view it as a chance to see the lagoon from below, not as a dedicated wildlife survey.

You should also pack a towel and a complete change of clothes. Even if you plan only a brief swim, an open speedboat ride in wet swimwear can become uncomfortable.

Île aux Phares and the force of the ocean

Île aux Phares is the most distinctive stop for anyone who likes history. Its old lighthouse dates back more than 200 years and is now a historical monument. The lighthouse gave the island its name, and its position helped guide ships through the waters around Mauritius.

The island is also linked to the naval battle of Grand Port in 1810, when French and British forces fought in the area. It was the only naval victory of Napoleon’s navy and is commemorated on the Arc de Triomphe in Paris. You do not need to be a military-history specialist to appreciate the setting. The island makes the story tangible because the water around it was part of the battlefield.

The natural setting is just as memorable. On one side, the lagoon can look calm and turquoise. On the other, waves from the Indian Ocean break hard against the island’s outer reef. That sharp change in mood is the reason this stop deserves more than a quick photograph.

The schedule allows about 20 minutes at Île aux Phares, so do not expect a long walk or a full lighthouse tour. The access details are limited, and the tour may focus on viewing the island from the boat or a brief stop nearby. Still, the combination of old stone, open ocean, and colonial history gives this part of the route a character the beach stops do not have.

Île de la Passe and Île aux Aigrettes

Île de la Passe is mainly a sightseeing pass-by. It played a role in the same French and British naval battles connected with Grand Port. You may not spend much time ashore, but passing it by adds context to Île aux Phares. The two islands are part of the same historic waterway rather than isolated attractions.

Île aux Aigrettes brings the focus back to nature. It is a protected reserve known for rare species and native vegetation. The tour schedule allows about 45 minutes here for an aperitif and swimming. That pairing is a little unusual, but it gives you a relaxed pause between the more active boat sections.

Because Île aux Aigrettes is protected, do not expect a free-roaming island visit or a long independent hike. The information provided does not promise a reserve walk or a formal conservation talk. Think of it as a stop near a protected natural area, with time in the water and a drink.

This part of the route may suit you if you like quiet scenery and short swims. If you are booking mainly for wildlife, ask exactly what portion of the reserve you will access. The tour promises the setting and native vegetation, but not a specific animal sighting.

Fouquets Island and the dolphin-watching claim

The route includes Fouquets Island for dolphin watching and then a photo stop of about 20 minutes. The available details do not promise a guaranteed sighting, so keep your expectations sensible. You may scan the water and enjoy the boat position, but wildlife is never a fixed appointment.

The stop adds another change of scenery without requiring a long shore visit. It is also a good time to keep your camera nearby and follow the captain’s instructions. Since the trip moves between several islands, the day works best when you treat each location as a chance to see something different rather than demanding a long stay at every stop.

BBQ lunch, drinks, and the value of the price

At about $88 per person, the tour is not the cheapest way to reach Île aux Cerfs. A simple transfer or beach day could cost less. The price makes more sense if you want several sights in one outing and value having a skipper manage the route.

You receive lunch and drinks, including local rum and soft drinks. The BBQ is served on Île aux Cerfs, with about two hours for eating and swimming. That saves you the trouble of arranging lunch during a day when you are moving between islands.

The value depends heavily on the group size. On a comfortable small-group departure, the price covers speedboat transport, local guidance, multiple stops, a waterfall, lagoon time, and a beach meal. On a crowded boat, the same price may feel less attractive because seating and shade become limited.

A private option can be worth considering for couples, families, or friends who care about setting the pace. One group changed to a private tour and was able to decide where to stay and for how long. The exact private price is not provided, so ask before agreeing, but the extra control may matter more than saving a little money.

The biggest uncertainty is snorkeling. Lunch and drinks are clearly included, but the information about equipment and the session conflicts. Get clarification before booking if snorkeling is central to your decision.

Who will enjoy this tour most

I would recommend this outing to you if you want a full east coast sampler rather than one long beach stay. Families with older children, couples, and groups of friends can all find something to like, provided everyone is comfortable with boat movement and sun.

It also suits you if you want a mix of soft adventure and easy sightseeing. You can swim, snorkel, and ride quickly between islands, but you do not need to commit to a demanding hike or a long expedition.

This is less suitable if you have back problems, need wheelchair access, or want extensive shade. The activity is not suitable for wheelchair users or people over 95 years old. You should also reconsider it if you dislike close seating, since the speedboat can feel cramped when full.

Bring sunglasses, a sun hat, sunscreen, flip-flops, swimwear, a towel, spare clothes, and goggles. I would add a waterproof phone pouch and a refillable water bottle, though those items are not specified by the operator. Keep your kit compact because space on the boat may be limited.

The tour is offered in English and French. Lucas is one of the named guides, and the captain plays an important role in the day, especially if you arrange a private departure. The best experience will come from asking clear questions at the jetty about group size, snorkeling equipment, and the exact timing of the stops.

Should you book the five-island tour?

Book it if you want variety, a fast boat, a beach BBQ, and a useful introduction to Mauritius’s east coast. The old lighthouse, the battle sites, the waterfall, and the lagoon give the day more substance than a basic island transfer.

I would choose it for a first visit when you have only one free day for this part of Mauritius. I would be more cautious if your priority is peace, shade, or serious snorkeling. In that case, confirm the boat capacity and snorkeling arrangements first, or pay for a private trip if the budget allows.

The strongest reason to go is the range of experiences packed into six hours. The strongest reason to hesitate is the possibility of a crowded, sun-exposed speedboat. Make those two points your booking test.
