5 Islands All-Inclusive Speedboat w/Snorkeling Sea Turtle
Mauritius packs a lot into this nine-hour speedboat day: five islands, a waterfall, several snorkeling stops, a beach BBQ, and a cruise across the island’s largest lagoon. The trip is built for people who want movement and variety rather than one quiet beach and a slow boat ride.
I like the small group of up to eight and the mix of active and easygoing stops. I also like that lunch, drinks, snorkeling gear, and snacks are included, which makes the $125 price easier to justify. The main concern is consistency: one guide cancellation left a German-speaking group without the promised commentary, Blue Bay Marine Park, and open bar, so the actual day can depend heavily on the crew and conditions.
Key points to know before booking

- Five east-coast islands in one day: You cover Ile aux Cerfs, Ile aux Phares, Ile de la Passe, Ile aux Aigrettes, and Ilot Margenie.
- A fast boat with a limited group: The speedboat gives you more coastline in one day, while the eight-person limit keeps the outing fairly personal.
- Blue Bay snorkeling is a major highlight: The marine park is the planned spot for tropical fish, with more than one snorkeling session during the day.
- Lunch is served on Ile aux Cerfs: Expect grilled chicken, grilled fish, rice, pasta, garlic bread, salad, snacks, and drinks.
- Wildlife sightings are possible, not guaranteed: The package includes the chance to see dolphins and sea turtles, plus monkeys near Grand River South East.
- Service delivery matters: Confirm the guide language and core stops before departure, especially if Blue Bay and the open bar are important to you.
A fast start from Trou d’Eau Douce

The day begins and ends at the jetty in Trou d’Eau Douce. Search for Debarcader Trou D’eau Douche on Google Maps, then look for the jetty when you arrive. Hotel pickup and drop-off across Mauritius are not included, although they can be arranged for an extra charge.
From the first run of the engine, this feels different from a standard sightseeing cruise. You are on a powerful speedboat, moving across the waves and covering the east coast at a brisk pace. That speed is useful here because the itinerary is ambitious. Five islands plus a waterfall and marine park would feel difficult on a slow vessel.
The tradeoff is comfort. A speedboat gives you wind, spray, engine noise, and a bumpy ride when the sea is lively. Bring sunscreen and a camera, and wear clothing that can handle water. The day is long, so you should be happy sitting in the open air for much of it.
The group limit of eight is a real advantage. You are not lost in a large boat crowd, and there is a better chance to speak with the skipper or guide. One especially well-rated outing had only six people, with skipper Sino praised for running a clean, fast boat and creating a memorable day.

Ile aux Cerfs sets the pace

Your first stop is Ile aux Cerfs, where you have about 45 minutes to look around and enjoy refreshments. This first visit is short, so think of it as an introduction rather than your main beach stay.
Ile aux Cerfs is the best-known island on this route, with white sand, swimming areas, and a wide choice of water activities. The short early stop gives you a quick look before the boat moves on to the river and smaller islands. If you want beach time, do not worry. You return later for about two hours.
The split visit works well. You get a taste of the island early, then return after the sightseeing portion for lunch and relaxation. It also keeps the morning from turning into a long stay at the first stop while the other sites wait.
Grand River South East and the waterfall

The boat then heads toward Grand River South East, where a waterfall drops toward the Indian Ocean. The view is one of the more distinctive parts of the route because it brings together freshwater, cliffs, river scenery, and open sea.
There is also a chance to see and feed wild Mauritian monkeys near the waterfall. This is an unusual stop, but you should treat the animal encounter as an add-on rather than the main reason to book. Wildlife can be unpredictable, and the exact experience may vary.
The waterfall stop also gives the day a change of rhythm. After the speedboat ride, you get a calmer look at one of Mauritius’s natural sights. One strong outing included both dolphins and the monkeys before the waterfall, showing how much wildlife can add when conditions line up. Still, dolphins and sea turtles are listed as possible sightings, not guaranteed encounters.
Three island crossings with a history angle

After Grand River South East, the route continues toward Ile aux Phares, then passes Ile de la Passe on the way to Blue Bay. It later includes Ile aux Aigrettes and Ilot Margenie. The operator presents this part as an island discovery with a history and exploration theme, but the available information does not promise a detailed historical talk at every stop.
That point matters if you are booking mainly for interpretation. The guide is meant to provide commentary in English, French, German, Italian, or Romanian, but the quality of the information depends on who is leading the trip. One serious service failure occurred when the German-speaking guide became ill and no English-speaking guide was provided. The group had only the skipper and received little information about the five islands.
I would confirm the language before you leave the jetty. If your chosen language is important, ask who will be guiding the boat that day. Skipper Sino received particularly strong praise for the boat and the way he handled the outing, but a skipper alone may not provide the same historical explanation as a dedicated guide.

Blue Bay Marine Park is the key water stop

The boat continues to Blue Bay Marine Park, where the planned snorkeling takes place among tropical fish. Several snorkeling sessions are included, so this is not a tour where you simply look at the water from the rail and move on.
Snorkeling gear is provided, which saves you from packing your own mask and fins. You should still bring sunscreen, and a camera if you want photographs. The tour promises views of sea turtles and dolphins, but those sightings are opportunities rather than fixed parts of the schedule.
Blue Bay is a major reason to choose this excursion over a simple beach transfer. You get a chance to see the marine side of Mauritius and spend time in the water, not just photograph islands from the boat. The stop is also where the itinerary has the most to lose if timing or weather changes.
One disappointing outing did not reach Blue Bay Marine Park at all, and the snorkeling was described as ineffective. That does not prove the stop is always missed, but it is a useful warning. Before boarding, confirm that Blue Bay is on the day’s route and ask how many snorkeling stops are planned. If snorkeling is your top goal, you should not treat the itinerary as automatic.
Ile aux Aigrettes and the open bar

After Blue Bay, the boat passes by Ile aux Aigrettes for refreshments. This is also when the all-inclusive bar is supposed to open. Drinks include rum, wine, beer, juice, soft drinks, and water, with unlimited snacks included as well.
The open bar has practical value on a full-day boat outing. You do not need to carry enough drinks for nine hours, and the combination of water, soft drinks, and alcohol gives you choices throughout the day. Mauritian rum cocktails are part of the promised service, prepared by the onboard barman.
Keep your expectations sensible. The open bar is an inclusion, not a guarantee that the boat will feel like a floating cocktail lounge. A service problem on one outing meant the bar was not offered at all, and the group had to serve its own nonalcoholic drinks. Confirm the bar service early if it matters to you, and drink carefully in the sun and on a moving boat.
The return route heads back toward Ile aux Cerfs, passing Ilot Margenie. This section is less about a long stop and more about seeing the lagoon from the water. The boat gives you changing views of sandbanks, islands, and open water while repositioning for lunch.
Two hours on Ile aux Cerfs
The longer Ile aux Cerfs visit is the relaxed center of the day. You have about two hours on the white sand to swim, sunbathe, drink coconut water, or choose optional water activities such as parasailing and a tube ride.
These activities are mentioned as things you may enjoy, but the $125 price does not state that parasailing or the tube ride is included. Ask about the cost before taking part. The same advice applies to any activity sold on the beach.
This break is important after the busy morning. Five islands and a marine park sound exciting, but they also mean frequent movement. Two hours on one beach lets you stop chasing the schedule and simply enjoy Mauritius.
The lunch is prepared on the beach and includes grilled chicken, grilled fish, rice, pasta, garlic bread, and salad. Snacks and drinks are included as well. That is a substantial spread for a boat excursion, especially when you consider the time and effort saved by not having to find a restaurant between stops.
Live music or a sega show is also part of the planned beach setting. Sega is a Mauritian musical and dance tradition, so this can add a local touch to what might otherwise be a standard beach lunch. The quality and scale can vary. One small group was seated away from the main activity and found the entertainment limited to one guitarist, with little chance to hear the music.
If the cultural performance matters to you, ask where lunch will be served and what entertainment is scheduled that day. The meal itself appears to be a stronger and more dependable part of the package than the show.
What the $125 price really covers

At $125 per person, this is not the cheapest way to spend a day on the water. It is also not just a boat ride. The price covers nine hours, five island visits, a waterfall stop, lagoon cruising, snorkeling equipment, several water sessions, beach BBQ lunch, snacks, alcoholic and nonalcoholic drinks, and a small group.
That list makes the price reasonable for someone who wants an all-day package. You are paying for transport between widely separated sights as well as food and refreshments. A separate boat trip, lunch, drinks, and snorkeling arrangement could quickly approach the same amount, though the comparison depends on local prices and availability.
The value drops if the central inclusions do not happen. Missing Blue Bay, skipping snorkeling, losing the guide, or not receiving the open bar changes the day from a full package into a basic speedboat outing. For that reason, I would place more weight on confirmed operations than on the headline list of inclusions.
The booking terms are flexible: you can cancel up to 24 hours ahead for a full refund, and reserve now while paying later. That helps if your weather plans are still moving, but it does not solve the problem of poor sea conditions or last-minute staffing changes.
Who should book this speedboat day

I would choose this tour if you want to see a lot of the east coast in one outing and prefer a small, active group. It suits couples, friends, and families who enjoy snorkeling, boat speed, beach time, and a packed schedule.
It is also a good match if you like having the day organized. Lunch, drinks, gear, island transport, and major stops are arranged in one package. You can spend less time working out boat connections and more time looking at the coast.
I would be more cautious if you want a quiet cruise, detailed historical guiding, or a guaranteed wildlife encounter. The engine is powerful, the schedule is full, and the guide language needs confirmation. It is also not ideal for someone who dislikes sun, spray, or an open speedboat for long periods.
The itinerary offers optional parasailing and a tube ride, but the supplied details do not say those activities are included. Budget separately if you want them. Hotel transfers also cost extra, so add that amount when comparing the total price with other excursions.
My call: exciting, but confirm the essentials
I would book this for the small group, fast boat, Blue Bay snorkeling, and beach lunch, provided the operator confirms those points before departure. The combination of islands, waterfall, marine life, and Ile aux Cerfs gives you a broad taste of Mauritius’s east coast in one day.
I would not book it blindly if your chosen guide language is essential or if missing Blue Bay would ruin the outing. Ask who the guide will be, confirm that Blue Bay Marine Park is included that day, and check that the open bar and lunch arrangements are ready. With those basics in place, $125 can be fair value for a busy, varied day. Without them, the price is harder to defend.
