Best Diving Spots in Mauritius: A Local Guide to Scuba Diving Sites, Reefs, Wrecks, Walls and Dive Centres Around the Island

Best Diving Spots in Mauritius - Your Local Guide

Mauritius is one of the most underrated scuba diving destinations in the Indian Ocean. Most travellers know the island for beaches, lagoons, catamaran cruises and luxury resorts, but just beyond the reef there is another Mauritius: walls, arches, caverns, wrecks, coral gardens, volcanic rock formations, drift dives, reef fish, turtles, rays, moray eels, nudibranchs, barracuda and seasonal big-fish encounters.

What makes diving in Mauritius special is the variety. The island is surrounded by coral reef, but each coast feels different. The north is known for island dives around Coin de Mire, Flat Island, Round Island and Snake Island. The west is famous for Flic en Flac, Cathedral, Rempart Serpent, Aquarium and wreck diving. The east offers Belle Mare reef dives, drift dives, wrecks and pelagic encounters. The southeast gives access to Blue Bay and an unspoiled lagoon environment. The southwest around Le Morne is more exposed and adventurous, with drift dives and big-fish potential.

Official Mauritius tourism information notes that the island has more than 100 dive sites within easy reach of the coastline, including sunken wrecks that have become artificial reefs. It also highlights The Cathedral as one of the island’s most famous underwater landscapes, known for its drop-offs, boulders, caves and arches.

This guide focuses mainly on the best scuba diving spots in Mauritius, with a practical overview of the best regions, famous dive sites, what level they suit and a few trusted dive centres to help you plan your underwater adventure.

Why Go Diving in Mauritius?

Scuba diving in Mauritius is perfect for travellers who want to see more than the beach. The island’s underwater world is shaped by coral reefs, volcanic formations, channels, wrecks and reef passes. This creates a wide range of dive styles, from easy beginner reef dives to deeper walls, caverns, drift dives and advanced sites.

Mauritius diving is best for:

• Beginner divers

• Certified Open Water divers

• Advanced divers

• Wreck diving fans

• Underwater photographers

• Families with teenagers

• Honeymooners looking for adventure

• Travellers staying in Flic en Flac, Grand Baie, Belle Mare or Le Morne

• Divers who want reef fish, turtles, rays and dramatic underwater topography

• Visitors who want to combine diving with beaches, catamarans and nature

The best thing about diving in Mauritius is that you can choose your coast depending on your level. Beginners can enjoy shallow reef sites like Aquarium near Flic en Flac or sheltered training areas near northern lagoons. More experienced divers can head to Cathedral, Rempart Serpent, Coin de Mire walls, Belle Mare drift dives or Pass St Jacques near Le Morne.

Best Diving Regions in Mauritius

North Mauritius

Best for: island dives, reef walls, caves, dive safaris, clear water, variety
Main areas: Grand Baie, Pereybere, Trou aux Biches, Coin de Mire, Flat Island, Round Island

North Mauritius is one of the best diving regions on the island because it gives access to offshore islands and varied underwater landscapes. From Grand Baie, Pereybere and Trou aux Biches, dive boats can reach reefs, walls, wrecks and island sites.

The north is especially good for certified divers who want variety. Sites around Coin de Mire are among the best-known in Mauritius, and some dive operators also organise full-day dive safaris towards Flat Island, Round Island and Snake Island, depending on conditions.

Octopus Diving Centre is a well-known north coast dive centre based around Pereybere. It describes its location as ideal for diving around Grand Baie, Pereybere, Trou aux Biches, Coin de Mire, Flat Island, Snake Island and Round Island, with small groups and a multilingual team.

West Mauritius

Best for: famous dive sites, caverns, walls, wrecks, underwater photography
Main areas: Flic en Flac, Wolmar, Tamarin, Black River

West Mauritius is home to some of the island’s most iconic dive sites. If you ask local divers for famous Mauritius dive spots, Cathedral and Rempart Serpent will almost always come up.

Flic en Flac is the centre of west coast diving. The sites are close by boat, varied and suitable for different levels. Beginners can start at easier reef sites, while advanced divers can explore walls, caverns and deeper sites.

Sundivers Mauritius is based on the west coast at La Pirogue Hotel, Wolmar, Flic en Flac, and offers PADI and SSI courses. Its website says it is accessible to divers outside the resort and offers pick-up services in Flic en Flac.

East Mauritius

Best for: drift dives, reef dives, wrecks, pelagic potential, resort-based diving
Main areas: Belle Mare, Palmar, Poste de Flacq, Trou d’Eau Douce

East Mauritius is less often discussed than the west by casual visitors, but it has excellent diving. The east coast is known for reef dives, drift dives, wrecks and stronger pelagic potential in some areas.

Crystal Diving Centre is based at Crystals Beach Resort in the Belle Mare / Palmar area and describes the east coast as known for big pelagic fish, drift dives, reef dives and the Ruang Lap wreck. Blues Diving is located at Constance Belle Mare Plage and states that non-hotel guests can also book, with year-round average sea temperature around 25°C and visibility around 10–15 metres.

Southeast Mauritius

Best for: Blue Bay, marine park environment, beginner-friendly lagoon experiences, coral and reef fish
Main areas: Blue Bay, Mahébourg, Pointe d’Esny, South East Lagoon

The southeast is best known for Blue Bay Marine Park, one of the island’s most famous marine areas. It is especially popular for snorkelling, but there are also dive centres and dive experiences in this region.

Scuba World Diving Centre describes itself as a PADI 5 Star Resort offering diving in an unspoiled South East lagoon. This area is especially useful for travellers staying near Blue Bay, Mahébourg, Pointe d’Esny or the airport.

Southwest Mauritius

Best for: Le Morne scenery, drift dives, advanced dives, big-fish encounters
Main areas: Le Morne, La Gaulette, Bel Ombre, southwest reef passes

The southwest is more dramatic and can be more exposed. It is best for divers who want something more adventurous, especially around Le Morne. Some dives here can involve currents and reef passes, so it is important to go with experienced operators.

Best Diving Spots in Mauritius

1. Cathedral — Flic en Flac

Best for: advanced divers, caves, arches, walls, underwater photography
Region: West Mauritius
Type: wall, cave, cavern, boulder formation
Typical level: advanced or confident certified divers

Cathedral is probably the most famous dive site in Mauritius. Located off the west coast near Flic en Flac, it is known for dramatic underwater architecture: arches, caves, boulders, deep drop-offs and shafts of light that create a cathedral-like atmosphere underwater.

PADI describes Cathedral as a site of arches and caves off Flic en Flac, where advanced divers can encounter lobsters and reef fish among boulders and dramatic drop-offs. It lists the site as a boat-entry cave and wall dive, with Advanced Open Water and Rescue Diver training suggested for the site.

This is a must-dive for experienced divers visiting Mauritius. It is not only about marine life. The real attraction is the topography: the feeling of moving through underwater stone passages, light beams and vertical structures.

Why dive Cathedral:

• One of the most famous dive sites in Mauritius

• Dramatic caves, arches and walls

• Excellent for underwater photography

• Strong sense of underwater atmosphere

• Good for advanced divers

Local tip: Cathedral is best enjoyed when visibility is good and current is manageable. Do not rush the dive. The beauty is in the light, rock formations and slow movement through the site.

2. Rempart Serpent / Snake Reef — Flic en Flac

Best for: underwater photographers, reef fish, moray eels, macro life, advanced divers
Region: West Mauritius
Type: reef, boulders, sandy bottom
Typical level: intermediate to advanced

Rempart Serpent, also known as Snake Reef, is another famous Flic en Flac dive site. It gets its name from the long, snake-like shape of the reef structure. This is one of the best sites in Mauritius for photographers because of the variety of marine life packed around the reef.

Divebooker describes Rempart Serpent as a site around 15 minutes from Flic en Flac, with strong currents possible, making it better for experienced divers. Sundivers describes Snake Reef as a northern Flic en Flac site facing the cliffs of Médine Sugar Estate, with a maximum depth around 26 metres and an advanced level recommended.

Expect boulders, sandy bottom, moray eels, reef fish and good macro opportunities. Conditions can vary, so listen carefully to the dive briefing.

Why dive Rempart Serpent:

• One of the best west coast dive sites

• Good for underwater photography

• Moray eels and reef life

• Interesting reef shape and boulder formations

• Strong option for experienced divers

Local tip: This is a good Nitrox dive if you are qualified and the operator offers it, because much of the site sits around deeper recreational depths.

3. Aquarium — Flic en Flac

Best for: beginners, first certified dives, colourful reef fish, relaxed diving
Region: West Mauritius
Type: shallow reef
Typical level: beginner to certified

Aquarium is one of the best beginner-friendly dive sites in Mauritius. As the name suggests, this site is known for colourful reef fish and easy underwater life. It is a good choice for Open Water divers, refreshers or anyone who wants a relaxed dive without the intensity of deeper walls and caverns.

ScubaGo lists Aquarium in Flic en Flac as a boat-entry site between around 5 and 20 metres, ideal for beginners because of its shallow depth and colourful reef fish. Sea Urchin Diving also describes Aquarium as ideal for beginners, with many colourful reef fish between 5 and 20 metres.

Best for: wreck diving, beginner-to-intermediate divers, artificial reef life
Region: West Mauritius
Type: wreck
Typical level: certified divers

Tug II is one of the accessible wreck dives near Flic en Flac. Wrecks in Mauritius often act as artificial reefs, attracting fish and creating structure in the underwater landscape.

ScubaGo describes Tug II as a former tugboat that worked in Port Louis and was sunk in the 1980s for scuba diving, sitting at around 19 metres. This makes it a good wreck option for divers who are not ready for very deep or technical wreck dives.

Why dive Tug II:

• Accessible wreck dive

• Good artificial reef life

• Interesting structure

• Manageable depth for certified divers

• Good west coast variety

Local tip: Wreck dives are best done slowly. Look into cracks and structure carefully, but avoid touching or entering anything unless properly trained and briefed.

Region: North Mauritius

Typical level: beginner to advanced depending on site

Coin de Mire, also known as Gunner’s Quoin, is one of the best diving areas in North Mauritius. The island sits off the north coast and has several dive sites around it. Conditions can be excellent, and the underwater scenery is more dramatic than many lagoon-adjacent reefs.

Bluewater Dive Travel describes Coin de Mire as possibly the best diving in Mauritius, with excellent visibility, wall and wreck diving, and the chance of large pelagic encounters. Travel dive writing also notes that Coin de Mire is about 9 km offshore from Cap Malheureux and has multiple dive sites, including easier conditions at Confetti Bay and more exciting sites such as the Wall and Pyramids for certified divers.

Why dive Confetti Bay:

Final Local Tip

The best diving spot in Mauritius depends on your level and the type of dive you want.

Choose Flic en Flac if you want the island’s most famous dive sites, including Cathedral, Rempart Serpent, Aquarium and Tug II. Choose the north if you want island diving around Coin de Mire, Flat Island, Round Island and Snake Island. Choose the east if you want Belle Mare reef dives, drift dives and wreck options. Choose Blue Bay and the southeast if you want coral, lagoon scenery and beginner-friendly marine experiences. Choose Le Morne if you are a confident diver looking for a more adventurous southwest setting.

Mauritius is beautiful above the water, but diving shows you another side of the island. Beneath the lagoon and beyond the reef, you find arches, walls, wrecks, reef fish, caves, turtles, moray eels and a quiet underwater world that many visitors never see.
