The best water activities in Mauritius

Sea and lagoon: what defines Mauritius

Mauritius is entirely surrounded by a coral barrier reef, which creates a shallow turquoise lagoon — typically between 1 and 5 metres deep — sheltered from large ocean swells. This dual geography is unique: you can practically wade through the water for hundreds of metres while watching coral life, while just 200 metres beyond the reef, the ocean plunges to depths of over 200 metres.

It’s this double geography that makes Mauritius exceptional for water activities: a calm lagoon for beginners, families and surface snorkeling, and an open sea just beyond for big-game fishing, wall diving, and dolphin and whale watching.

Here’s our selection, sorted by type of experience.

In brief

Best time to go	Year-round for the lagoon; May to October for the calmest sea and kitesurfing

Catamaran: the king of outings

A catamaran trip combines three pleasures in one day: sailing through a postcard setting, a swim or snorkeling stop at unspoiled spots, and a Creole lunch on board. It’s the most representative experience of what Mauritius has to offer, and the one that always brings back the best memories.

Classic trip to Ile aux Cerfs (east coast)

The classic: departure from Trou d’Eau Douce, a leisurely sail to Ile aux Cerfs, snorkeling, a BBQ lunch on the boat, a swim, and return in the late afternoon.

Northern islands tour from Grand Baie

An equally spectacular option for those staying in the north: sailing to Coin de Mire, Ile Plate and Ilot Gabriel. Snorkeling at several spots and a Creole lunch.

South-west catamaran and Ile aux Benitiers

For travellers based in Flic-en-Flac, Le Morne or Tamarin: departure from La Gaulette, dolphin watching along the way, snorkeling at Crystal Rock in exceptionally clear water.

Sunset cruise

A short format (2h30) ideal for couples or those who’ve already had a big day at sea. Aperitif, snacks, and a sunset over the lagoon.

Snorkeling: easy, accessible, stunning

Mauritius is probably the best place in the world to try snorkeling without sophisticated gear. The lagoon is shallow, currents are practically nonexistent, and the water stays at 24-28°C year-round.

Blue Bay Marine Park

The reference for guided snorkeling. A protected marine area since 1997, well-preserved coral beds, visibility of up to 25 metres, and regular sightings of green turtles, parrotfish and damselfish of every colour.

For non-swimmers or young children

The glass-bottom boat lets you observe the seabed without getting wet. Ideal for children under 6 or people not fully at ease in the water.

Quad bike + snorkeling combo

For those who want variety in half a day: a quad bike tour through the Mauritian countryside followed by snorkeling at a prime spot.

Dolphins: an encounter not to be missed

Mauritius is home to two resident dolphin species (spinner dolphins and bottlenose dolphins) that patrol Tamarin Bay and the Black River area daily. Trips depart early (around 6am) for calmer seas and more active cetaceans.

Classic dolphin trip in Tamarin

Dolphins + humpback whales (July-November)

During the whale migration season (July to November), a dedicated trip lets you also spot humpback whales. A longer outing (4h), with a naturalist guide.

Dolphins + Chamarel full-day

A combined format for those who want to make the most of a day: dolphins in the morning, the Seven Coloured Earths and a rum distillery in the afternoon.

Scuba diving: for certified divers and beginners

The island has around twenty FFESSM/PADI diving clubs spread across the main tourist areas. Sites include:

• Trou aux Biches and Pointe aux Piments (north): Aquarium (15 m), Holts Rocks, the Stella Maru wreck
• Coin de Mire (far north): Le Confidence Cave, Djabeda Reef — sites for advanced divers
• Flic-en-Flac (west): La Cathédrale (an underwater gallery), L’Aquarium, Couline Bambous
• Blue Bay and Mahebourg (south-east): Sirius Wreck, Roches Zozos, Colorado

An exploration dive costs €50 to €70, gear included. A discovery dive (first try without certification) costs €60-80. Expect €350 to €450 for a PADI Open Water course over 3-4 days. Our guide to snorkeling and diving in Mauritius covers the centres and recommended periods in detail.

Board sports: kite, surf, wakeboard, paddle

Kitesurfing at Le Morne

Le Morne (south-west) is world-famous for kitesurfing: steady trade winds between May and October (15-25 knots), a flat lagoon sheltered by the reef, and an outer wave (One Eye) for experienced riders. Level required: independent for kiting. Several schools offer beginner courses (6 hours over 2 days for €280-350).

Surfing in Tamarin

Tamarin’s left-hander is a legendary wave of the Indian Ocean, surfable between June and October. Level required: advanced. A few schools in Tamarin and Black River offer rentals and beginner lessons on more accessible waves at La Preneuse.

Wakeboarding and water skiing at Ile aux Cerfs

A flat lagoon, operators on the main beach. Expect 1,000 to 1,200 rupees (€20-24) for 15 minutes of wakeboarding.

Stand-up paddleboarding

Practically every beach lets you rent a paddleboard (400-600 rupees per hour). Recommended spots for beginners: Mont Choisy (north), Belle Mare (east), Flic-en-Flac (west), Le Morne (south).

How to choose among all these options

If you only have one day at sea: catamaran (Ile aux Cerfs or Benitiers depending on your base). It’s the best all-round choice.

If you have 2-3 outings to plan: a catamaran + a dolphin morning + snorkeling at Blue Bay if you’re based in the south-east. That covers all the bases.

If you’re a family with young children: glass-bottom boat at Blue Bay + an afternoon shuttle to Ile aux Cerfs + paddle or kayak on your hotel beach. A safe and varied profile.

If you’re an active couple: south-west catamaran in the morning + kitesurfing at Le Morne in the afternoon (in season) + a wreck dive on another day. An intense, photogenic programme.

If you’re a solo traveller looking to meet people: a group catamaran trip (friendly atmosphere) + a group kite or paddle lesson (meet people over several days).

The golden rule: don’t overdo it. Three sea outings in a week is already a lot. The body tires faster than you’d think, between the sun, salt and wind. Two exceptional days fully enjoyed beat five outings half-endured.

Sea safety: what you need to know

The Mauritian lagoon is generally very safe, but a few points of caution avoid unpleasant surprises. The passes in the coral barrier (the openings where the lagoon meets the ocean) can generate noticeable outgoing currents, especially at low tide: don’t approach them alone while free snorkeling, and always follow your guide’s instructions on organised trips. Stonefish, hard to spot due to their perfect camouflage on the seabed, make water shoes worthwhile in rocky or shallow areas.

The tropical sun, often tempered by the wind, burns faster than it feels: waterproof sunscreen (ideally reef-safe) and a UV-protective rash guard limit sunburn on long boat trips. Finally, always check that your travel insurance covers the water sports you plan to do (diving, kitesurfing) before booking; our guide to travel insurance for Mauritius covers this in detail.

Budget for a week of water activities

Over a week’s stay, a couple alternating a catamaran trip, a dolphin outing and a guided snorkeling session typically spends between €150 and €250 per person. Add €60 to €120 per person if you include a diving session or a kitesurfing beginner course.

Families can cut costs by relying on free or low-cost independent activities: renting a paddleboard or kayak on the hotel beach, free snorkeling on equipped public beaches such as Trou aux Biches or Flic-en-Flac, where you can enjoy beautiful coral life without booking a single outing. To plan your overall trip spending, our Mauritius budget guide remains the reference.

Frequently asked questions

What’s the best snorkeling spot in Mauritius?

Blue Bay Marine Park (south-east) remains the top spot thanks to its protected area, unique blue coral and 15-25 metre visibility. Trou aux Biches (north), Flic-en-Flac (west) and Le Morne (south-west) also offer good reef life, especially at the edges of the reef.

Can you go diving in Mauritius year-round?

Yes, diving is possible from January to December, with optimal conditions between May and November (calmer seas, better visibility). Water temperature stays between 23 and 28°C depending on the season. The best-known sites are at Trou aux Biches, Coin de Mire and Blue Bay.

What budget should I plan for a sea outing?

Expect €25 to €35 for a short snorkeling session at Blue Bay, €45 to €70 for a dolphin trip in Tamarin, and €65 to €80 for a full-day catamaran trip with lunch. Private options range from €480 to €850 per boat for 2 to 8 people, depending on the level of service.

Are sea outings suitable for children?

Full-day catamaran trips accept children from age 4 (life jackets provided). The glass-bottom boat at Blue Bay is suitable from age 3. Dolphin trips require decent open-water ability from age 8-10. Board sports (kite, paddle, wakeboard) are accessible from the teenage years.

Do you need to know how to swim to go snorkeling?

Not necessarily: operators provide life jackets that let you float without difficulty, and some spots (Blue Bay near the beach, Ile aux Cerfs on the lagoon side) have less than 1.5 m of water over large areas. For deeper areas or open-sea outings, being able to swim is preferable.

Where can you swim with dolphins in Mauritius?

Dolphins frequent Tamarin Bay and the Black River area (west coast) year-round. Trips depart around 6am to benefit from calm seas and morning cetacean activity. Between July and November, you may also spot migrating humpback whales in the same area.

What’s the best time for water activities in Mauritius?

The lagoon can be enjoyed year-round thanks to consistently warm water, but the May to December period offers calmer seas and better visibility for snorkeling and diving. Kitesurfing benefits from the trade winds from May to October, while humpback whale season runs from July to November. Avoid January-February if possible, the wettest period and most exposed to cyclones.
