Table of Contents

The prominent Mark Twain eternalized Mauritius after quoting a Mauritanian: “Mauritius was made first and then heaven, heaven being copied after Mauritius.”

It’s arguably the most beautiful place on Earth, the land of the turquoise lagoons, where you’d be hard-pressed to find a spot that doesn’t look perfect. Scuba diving in Mauritius is just as heavenly and should be on every scuba diver’s bucket list.

In this guide, we’re covering everything you need to know about diving in Mauritius.

So let’s get started.

Scuba Diving In Mauritius

A fantastic destination for scuba diving and snorkeling, Mauritius has it all. The tropical waters are filled with all kinds of distinct flora and fauna of varying shapes and sizes, and the bottom of the sea is filled with crevasses, reefs, wrecks, caverns, and corals.

Its underwater topography is a sight to behold, and that’s the case on every side of the island.

Visibility is almost always great and can be as high as 40m, making the island’s popular dive sites even more spectacular. Plus it’s even easier to spot all your favorite creatures.

There’s a great variety of dive sites to explore, from shipwrecks, Trouz aux Biches being the most famous, to vibrant coral gardens, steep walls, and intriguing caverns.

The more popular dive sites in Mauritius tend to be in the North and West part of the island, but that’s not to say that the other parts are not worth checking out.

So let’s take a closer look at the best dive sites in Mauritius…

Best Dive Sites In Mauritius

A dive trip to Mauritius offers plenty of chances for different types of underwater experiences. There are a plethora of dive locations scattered all around the island.

There is no one single best place – all of them are amazing. Although, it’s important to note that not all sites are suitable for beginners. In no particular order or ranking, here are some fantastic places to dive in Mauritius.

Cathedral –  Located to the west of the island, the unique underwater topography and abundant marine life make this arguably the best dive site in Mauritius. With sheer drop-offs, dramatic arches, caves and connecting boulders, Flic en Flac is not to be missed! The dive itself starts at about 18m (60 feet) and finishes at about 30m (100 feet) on the neat, sandy floor. So you’ll need to have at least you’re advanced certification to explore this seriously stunning site.

St. Jacques – Another highlight of diving in Mauritius is this epic drift dive. Starting in the shallower part of the lagoon at about 5m (15 ft) depth, the current will carries divers over the reef pass, past the vibrant coral walls and epic rock pinnacles, all while keeping an eye out for the local grey reef sharks.

Hoi Siong No 6 – This intentionally sunk fishing vessel has been given a new lease of life as an artificial reef. Another one for advanced divers,  the Hoi Siong wreck sits at a depth of 29m (95 ft) and has transformed into a sanctuary that draws all kinds of sea creatures and divers alike.

Sirius Wreck – A unique dive site to visit.  The HMS Sirius was a British navy vessel, sunk in Battle Maeburg in 1810 and today lies 25m (80 feet) below.  The dive starts from a depth of 18m (59 feet) and finishes at 25m so again, you’ll need your advanced cert to access this one. It’s recommended to dive here between  November and May when the average water temperature stays at a very pleasant 28°C (82°F) making the whole dive a thoroughly enjoyable experience.

L’Aquarium – A beautifully relaxing dive, the Aquarium is located in a deep canyon down a very narrow gorge at a depth of about 20m (65 feet). The diving conditions here are generally good the entire year but the water temperature can vary quite significantly from 22C (71°F) in the low season (May-Sept) to 28°C ( to 82°F) in the high season (Nov to Feb).

The Shark Pit – Situated off the coast of Flat Island at the very northern tip of Mauritius, this famous site is only suitable for experienced divers due to the strong currents and rough seas.  Originally a cave, whose roof collapsed, the pit has become a sanctuary for sharks. Expect anywhere from 5 to 30 plus bull sharks, gray reef sharks, black tips, and Silvertips circling inside and around the pit.

Djabeda Wreck, Coin de Mire – Located off the village Cap Malheureux, the Djabeba Wreck is considered an advanced dive spot that sits at a depth of 25 to 35m (82 to 115 feet). The Djabeda was a Japanese fishing boat that sunk in 1998, it’s a spot that’s teeming with epic marine life. Diving here is accessible throughout the year, but the best months are from October to March, and the water temperature ranges from 24°C (75°F) to 28°C (82°F).

Coral Garden, Trou-aux-Biches – Located off the coast of Grand Baie village, the Coral Garden is a magnificently beautiful site. Made up of large rock structures that form giant steps completely covered in hard and soft corals. These unique formations combined with the giant gorgonian sea fans make this site an underwater photographer’s dream! Accessible for all levels, the coral garden is not to be missed when diving in Mauritius.

Stella Maru (Silver Star) Wreck, Trou-aux-Biches – A more advanced dive site, the impressive Silver Star Wreck lies between 22m (72 feet) and 39m (127 feet. Surrounding the wreck divers will encounter huge schools of angelfish and bannerfish, patrolling barracuda, and schools of trevallies. Keep an eye out on the wreck for the elusive frogfish!

Water Lily and Emily Wrecks, Trou-aux-Biches – Located on a sandy bottom at 25m (85ft), these two old water barges, sunk in the early 1980s, will delight all divers. Not only do they attract a very large number of fish, but their structures also create the most magnificent rays of light.  With almost no current and excellent visibility, it’s also a favorite for underwater photographers. Unfortunately, this is another site for advanced divers only, but as you can see it’s well worth getting your advanced or deep diver certifications when in Mauritius!

Best Time To Dive In Mauritius

You can dive year-round in Mauritius and the weather rarely affects the diving. November through to April offer the best visibility and highest diversity of marine life. The best time to dive in Mauritius is between October and December or March to April, these months offer the optimal conditions and you’ll avoid cyclone season.

In general, a 3mm wetsuit is recommended for diving in Mauritius. However, if like us you tend to get a little chilly towards the end of a dive you might want to consider a 5mm, especially if you’re planning to do multiple dives per day or visit earlier in the season. The water temperature ranges can be as low as 21 C (70F) on certain sites between November and February, or up to 30 C (86 F) between March and October.

The weather in Mauritius is mostly tropical, with hot humid summers moderated by southeast trade winds – which can affect the diving so is better avoided. Winters are warm, relatively dry, and less humid. Maximum temperatures occur from December to April when daily highs are 29° C/84° F to 30° C/86° F.

How To Dive In Mauritius

Scuba diving is usually organized by your resort. But if you prefer to stay in an apartment or AirBnB, then you can arrange diving directly with one of the local dive centers. This is a cheaper option and often gives you more flexibility on how and when you want to dive, and who with. The majority of accommodation options are located in the north and west of the island, which is also where the best dive sites are located!

Almost all dive centers in Mauritius offer equipment rental, although if you have your own dive gear they’ll usually give you a good discount. Dives are usually from a boat and led by divemasters – there can be tricky currents in places so it’s not recommended, and not really permitted, to dive without a guide. You’ll also find both guides and instructors who offer courses and diving in multiple languages, English, French, and German are the most common.

How To Get To Mauritius

Sir Seewoosagur Ramgoolam International Airpot (MRU) is located in the South-eastern part of the island and receives daily flights from Africa, Asia, and Europe.

It’s easy to rent a car in Mauritius and is a popular choice, and because of the island’s small size, taxis operate everywhere and easily reach any destination. Also, there is a public bus service.

Geography Of Mauritius

This island nation is located about 2000 km (1200 mi) east off the southern coast of Africa, and 900 km (540 mi) from Madagascar and nearby the Islands of Seychelles.

It’s comprised of the two main islands Mauritius and Rodrigues, and the outer islands Agaléga and St. Brandon (and two disputed territories, and is also considered part of the Mascarene Islands – also known as the Mascarenhas Archipelago – together with Réunion Island.

The inner parts of the islands are covered in rainforests and waterfalls, and they were the only known living location of the Dodo, unfortunately, made extinct after the islands’ habitation. Today, the interiors of the islands are a big draw for naturalists because of the national parks and the many endemic species they protect.

Its culture is interesting and unique and adds an extra layer to Mauritius’ charm, because its population is multi-ethnic, multi-religious, multicultural, and multilingual, making this destination a treat because every encounter with a local or a visitor tends to be unique.

Explore the mountainous interior where Black River Gorges National Park is to be found, rainforests, waterfalls, wildlife, and hiking trails. Visit also the Pereybere where Mangrove forest visits, water skiing, and swimming are possible.
