La Preneuse: Dolphin Watching and Snorkeling Speedboat Tour
Wild dolphins are the main event here, and they do not perform on cue. From La Preneuse Beach, you race across the water, watch for pods, and may slip into the sea for a close look as they pass below. The thrill comes from meeting animals in their own home, not from a staged show. This is active wildlife watching, not a slow boat ride with guaranteed photo poses.
I like the short two-hour format, which gives you a strong morning or afternoon outing without eating a whole day. I also like the practical help from the crew. Guides such as Feliciano, Andy, and Miguel have helped swimmers stay calm, find the dolphins, and even capture footage with a guest’s GoPro or phone.
The main catch is simple: you need to be comfortable in open water. Dolphins can swim about three meters below the surface and move quickly, so you may need to swim hard for a few minutes to keep up. On busy days, many boats can gather in the same area, which raises real questions about noise and space around the animals.
Key points to know before you book

- Wild dolphins, not a scheduled performance: Sightings are the goal, but the animals choose where and how long they stay.
- La Preneuse departure: Meet your skipper at the Martello Tower on La Preneuse Public Beach.
- A fast 20-minute ride: The speedboat gives you broad views of the coast and gets you out to the dolphin area quickly.
- A 15-minute lagoon snorkel: Expect colorful fish and the chance to spot species such as lionfish, scorpionfish, stonefish, or an octopus.
- Strong swimming helps: Non-swimmers are not suited to this trip, and even confident swimmers may find the dolphin swim tiring.
- English and French guides: The crew gives water advice and helps you make the most of your time in the sea.
La Preneuse Beach and the Martello Tower meeting point

The trip begins at La Preneuse Public Beach, beside the old Martello Tower called La Tour Martello. This is a useful meeting point because it is easy to identify, but transportation to the beach is not included. You need to arrange your own way there.
Arrive ready for the water. Bring your swimsuit, towel, sunglasses, sun hat, and biodegradable sunscreen. There is no food or drink included, so handle those needs before boarding or plan accordingly.
The beach start keeps the outing focused. You are not spending the first part of the morning collecting people from hotels or waiting through a long harbor process. You meet the skipper, board the boat, and get moving.

The 20-minute speedboat ride along Mauritius’ west coast

The first leg takes about 20 minutes. The boat skims across clear blue water, with views back toward golden beaches and the green coastal hills. This is the part where the trip feels like a proper speedboat outing rather than a simple transfer.
I like this ride because it gives you a quick change of scene. La Preneuse is behind you, the coast opens up, and you begin scanning the water for movement. The wind and spray are part of the fun, though you should protect your hat and sunglasses so they do not fly away.
A speedboat can be lively. If you prefer a quiet, steady cruise, this may feel bouncy, especially if the sea is choppy. The boat is described as comfortable, but comfort on a small craft depends heavily on the day’s weather.
The crew also uses this time to explain what to expect. Pay attention to their advice about entering the water, using the mask and snorkel, and approaching the dolphins. Their guidance matters because the animals may appear close to the boat but still be several meters below you.
Finding dolphins that set the pace

Most of the 85-minute middle section is given to dolphin watching and swimming. That generous block of time is one of the tour’s strongest features. You are not rushed into the water after one quick sighting, and you have time to watch the pod from the boat before deciding when to swim.
The important word is wild. Dolphins may surface beside the boat, pass underneath, or disappear and return somewhere else. One person described seeing a dolphin leap and spin, while other outings produced large numbers of dolphins and even sightings of sperm whales. Those extras are possible, not promised.
Do not picture dolphins calmly waiting beside a floating platform. They may travel about three meters under the surface, and they do not stop for photographs. If you enter the water, you may need to swim quickly for a couple of minutes to keep up.
That makes this better suited to a confident swimmer who already knows how to use a snorkel. If you are still learning to breathe through a tube, the excitement can turn into a mouthful of seawater. The crew can offer advice, but no guide can make open water feel easy for a non-swimmer.
You can also remain on the boat if you do not want to swim. A non-swimmer should not book this activity, according to the restrictions, but one person who chose not to enter the water still enjoyed seeing the dolphins and the view of Le Morne from the boat. The experience is not all or nothing, though the strongest encounters happen in the water.
What the dolphin encounter really feels like
The best way to approach this outing is to value the sighting itself. You may see dolphins close to the boat, then watch them vanish into blue water. You may get a brief swim beside them, or only a good view from above. That uncertainty is part of a wildlife encounter.
The guides work to position the boat and help you enter at a useful moment. Feliciano is specifically praised for friendly communication and for checking details before the trip. Andy and Miguel are also singled out for making the dolphin outing educational and helping swimmers feel safe and settled.
Photo help can be a welcome bonus. A guide or diver may take a GoPro or phone into the water and record footage while you concentrate on swimming. Do not treat this as a guaranteed service, since the supplied details do not promise underwater photography, but it has happened on the trip.
There is one ethical point you should consider before booking. At least one outing had around 20 boats trying to get near the dolphins. The concern was not aimed at this crew alone, and that person found the team respectful and communicative, but the wider scene felt crowded and aggressive toward the animals.
The responsible approach is to follow your crew’s instructions, stay quiet near the dolphins, and avoid chasing them beyond your ability. If the conditions feel uncomfortable, you can ask to return to the beach, as one participant did. The operator’s own team may be considerate, but it cannot control every boat in the area.

The 15-minute lagoon snorkeling stop

After the dolphin session, the boat reaches a viewpoint for a short snorkeling stop. The listed time is about 15 minutes, so think of this as a compact look at Mauritius’ underwater life, not a long reef excursion.
The equipment includes masks, snorkels, and fins. It is described as well maintained, which removes the need to pack your own gear, though you may bring personal equipment if you prefer a familiar fit.
The lagoon can bring a different mood from the open-water dolphin area. Here, your attention shifts from large moving mammals to small reef life. Look for colorful fish and keep an eye out for scorpionfish, stonefish, lionfish, reef fish, and perhaps an octopus.
Because the stop is short, listen closely to the guide’s tips. A few clear instructions about where to look, how to move, and how to conserve energy can make 15 minutes feel worthwhile. You will not have time to wander aimlessly and then begin searching just as the boat calls you back.
Water clarity changes with the season and weather. A clear day can make the lagoon feel much more rewarding, while wind or unsettled water may reduce visibility. This is a key reason not to judge the snorkeling solely by photographs or by another person’s experience on a different date.
The ride back and the two-hour time value

After the lagoon stop, the boat returns to La Preneuse Public Beach. The total time is about two hours, with roughly 20 minutes on the outbound ride, 85 minutes for dolphin watching and swimming, and 15 minutes for snorkeling.
I think the timing works well for most holiday plans. You get a serious wildlife encounter and a second water activity without sacrificing an entire day. One person who had tried a full-day trip elsewhere preferred this shorter outing, finding the length more manageable.
The trade-off is that the snorkeling stop is brief. If snorkeling is your main goal, a dedicated reef trip may give you more time underwater. This excursion is built around dolphins first, with snorkeling as a useful second act.
The schedule also leaves little room for delays. Conditions, dolphin movements, and boat traffic can affect how the time is used. The advertised structure is clear, but nature may force the skipper to adjust the order or length of each stop.
Is $58 a fair price?

At $58 per person, the tour sits in a reasonable range for a two-hour speedboat experience that includes a skipper and snorkeling masks and fins. You are paying for the boat, local guidance, access to a well-known dolphin area, and a second stop in the lagoon.
The value is strongest if you want a focused half-day activity. You do not pay for a full day of food, drinks, or transport, but you also do not receive any of those extras. The price covers the speedboat tour and snorkeling equipment only.
I would compare the cost with your priorities. If wild dolphins are high on your Mauritius list, the long 85-minute search period gives the price real weight. If you mainly want a leisurely cruise or a long reef session, the active swim and short snorkeling stop may feel less satisfying.
The reserve-now, pay-later option also gives you some planning flexibility, and cancellation is free up to 24 hours before departure for a full refund. Starting times vary, so check availability before building the rest of your day around it.
Who should book this La Preneuse outing?

This is a good fit for you if you:
- Swim confidently in open water.
- Can use a mask and snorkel without much coaching.
- Want wild animals rather than a staged marine show.
- Enjoy a fast boat ride and do not mind wind or spray.
- Prefer a two-hour activity over a full-day excursion.
- Are happy to treat dolphin swimming as a lucky opportunity, not a promise.
I would be cautious if you are pregnant, have a mobility impairment, use a wheelchair, have epilepsy, or do not swim. These groups are specifically listed as unsuitable for the activity.
Families need to make a realistic judgment about swimming ability. The boat ride may sound easy, but the dolphin part can require quick movement in open water. A strong swimmer who stays on the boat can still enjoy the outing, but a non-swimmer should not book it.
Practical ways to make the most of your time

Wear swimwear before you arrive, since the tour is short and you do not want to waste time changing. Bring a towel and biodegradable sunscreen, and use a hat and sunglasses during the boat ride.
Keep your expectations flexible. The dolphins may be below the surface, may travel quickly, and may not come close enough for a perfect photograph. You will get more from the trip if you watch their behavior and listen to the guide instead of treating every moment as a photo opportunity.
If you use a personal phone or GoPro, secure it well. Guides have helped with cameras in the water, but the listed inclusions do not promise photography. Ask the crew what is practical on the day.
Finally, listen when the crew talks about dolphin behavior. Staying calm, entering at the right moment, and avoiding noisy pursuit will help you get a better encounter and show respect for the animals.
Should you book it?
Book this tour if you want an energetic, compact introduction to Mauritius’ west-coast marine life and you are a capable swimmer. The strongest features are the long dolphin-watching period, the friendly French and English-speaking crew, the speedboat views, and the chance to add a lagoon snorkel without committing a full day.
Skip it if you need guaranteed dolphin contact, dislike crowded wildlife areas, or mainly want a relaxed cruise. The dolphins control the experience, visibility changes with weather, and other boats may be present.
For the right person, $58 is a fair price for a lively two-hour outing with genuine wildlife uncertainty. Go ready to swim, bring modest expectations about photos, and treat the dolphins as wild animals rather than performers.
