1. The S-pass

    📍 S tarting point: Sakouli beach

    🌡️ Water temperature: 25 – 30°C

    🤿 Level: beginner

    🐠 Fauna and flora: nudibranchs, groupers, grey sharks

The Passe en S separates two coral reefs and is undoubtedly Mayotte’s best-known diving spot. It is made up of multiple dive sites, home to extraordinary aquatic flora and fauna. Lined with numerous mooring buoys, it is 4 km long and can reach depths of up to 70 meters.

Here, we use the names of the buoys to decide which species to visit. Large groupers have chosen buoys n°4 and n°5. Humpback parrotfish have taken up residence around buoy no. 9. For turtles, on the other hand, buoy n°2 is certainly the best! The great safety of the site means that night diving is possible for an unreal moment.

2. Le Banc du Boa

    📍 D eparture point: M’Tsamboro beach

    🌡️ Water temperature: 25 – 30°C

    🤿 Level: N1

    🐠 Fauna and flora: stingray, lobster, platax, soft coral

No, there are no snakes waiting for you in this north-western site near the islet Choizil. However, this diving spot in Mayotte is home to lobsters, rays and gorgonians at depths of between 5 and 30 meters.

The coral reef in which these masters of the art twirl is a delight for underwater photographers, thanks to the excellent health of its corals. As you know, corals are not underwater plants, but animals!

If you’re lucky enough to visit the Banc du Boa, you may be able to admire the passage of much larger species on the offshore side.

3. Boat pass

    📍 D eparture point: Mzouazia

    🌡️ Water temperature: 25 – 30°C

    🤿 Level: N2

    🐠 Fauna and flora: barracudas, moray eels

Passe bateau is reserved for experienced divers, but what a spectacle! Far from the shore and rarely visited, this diving spot in Mayotte is located in the south of the island. You can learn to drift dive here, i.e. let yourself be carried along by the sea current. Advantages: you don’t need to exert much effort, as the current propels you along the entire length of the spot.

The first drop will take you to a depth of 40 meters, followed by a second at 80 meters for the more adventurous. A boat will pick you up at the very end of the « itinerary ». In the meantime, you’ll have the privilege of contemplating a rich pelagic fauna: sharks, rays, dolphins, tuna… And large moray eels will also be on hand close to the bottom. A guaranteed spectacle!

4. Passe Sada

Passe Sada is also a diving spot in Mayotte for experienced divers. It’s a favorite playground for dolphins, and you can sometimes even hear the haunting songs of whales. Particularly popular with turtles, this « lagoon within a lagoon » features an impressive vertical drop-off between 3 and 45 meters deep.

Passe Sada is quite a distance from the coast, promising some great underwater encounters. Easily accessible from Mzouazia, it’s the perfect place to perfect your diving skills. Perhaps even to obtain your Level 2 certification?

    📍 D eparture point: Pamanzi

    🌡️ Water temperature: 25-30°C

    🤿 Level: beginner

    🐠 Fauna and flora: gorgonians, porcupine fish, lobsters, coral

As its name suggests, this diving spot in Mayotte is located at the end of the runway at Dzaoudzi-Pamandzi airport. It’s a vertiginous drop-off descending to depths of under 60 meters. The good news, however, is that the site is accessible to all divers thanks to its weak currents. There are several corridors and tunnels where visitors can squeeze through.

Here, gorgonians, lobsters and scorpion fish go about their business. Occasionally, porcupine fish can be spotted. These astonishing animals swell with water and ruffle their spikes at the slightest annoyance! You’ll appreciate the brightness of the place and the clarity of the water, particularly remarkable even for the island of Mayotte.

    📍 D eparture point: Saziley beach

    🌡️ Water temperature: 25 – 30°C

    🤿 Level: beginner-confirmed

    🐠 Fauna and flora: rays, marine mammals

In the extreme south-east of the island, the 458-hectare Saziley reserve delights tourists from all over the world. The reserve comprises an absolutely stunning terrestrial section and an equally stunning underwater section. In the former, turtles come to lay their eggs on sublime beaches of multicolored sand. In the second, the islet of Mtsanga Tsoholé is home to corals bursting with life.

This snorkeling spot in Mayotte is ideal for those who want to enjoy the beach while discovering the coastal seabed. Scuba diving is also possible further offshore: rays and marine mammals are a regular feature. In fact, whales calve in the lagoon around August. If you happen to be here at this time of year, you know what you have to do!

7. Islet of Sable Blanc (snorkeling)

    📍 D eparture point: Mtsamboro

    🌡️ Water temperature: 25 – 30°C

    🤿 Level: beginner

    🐠 Fauna and flora: clams, hard corals, anthias, parrotfish

Head northwest of Mayotte to explore one of the island’s best snorkeling spots. Wait until low tide for the islet of Sable Blanc to emerge from the waves, then don your mask and snorkel and treat yourself to an exceptional underwater hike in an equally exceptional coral reef. The depth is shallow, barely 1 to 3 meters, allowing you to admire the hard corals. If you observe them carefully, you may even spot the little octopuses that hide there.

As you progress, colonies of hundreds of bright orange anthias act as a peaceful escort. The site is also home to several species of sergeant majors, parrotfish, butterflyfish and pinfish. Here again, we can’t recommend you enough to take advantage of Mtsamboro’s heavenly beaches. For sunbathing or a gourmet picnic (featuring extra-fresh seafood, of course), believe us, there are worse things to do.

    📍 D eparture point: N’gouja beach

    🌡️ Water temperature: 25 – 30°C

    🤿 Level: beginner

    🐠 Fauna and flora: clownfish, sea turtles, anemones

N’Gouja beach is one of the most popular tourist destinations in Mauritius. Between baobabs, jungle and turquoise water, it is for many the most beautiful stretch of sand on the island. One of Mayotte’s best snorkeling spots is just a few meters from the shore. In calm waters, the site is known to be home to sea turtles. Green and hawksbill turtles come to feed in the sea grass beds and give birth to their young.

There’s plenty to see, from coral and blue damselfish (fish of stunning turquoise color) to mischievous clownfish (like Nemo!) and iridescent angelfish. The area is teeming with underwater life and is ideal for an unforgettable family outing. The spot stretches over 200 meters offshore from the beach, with a maximum depth of just five meters. Given the amount of space to cover, it’s much easier to use flippers!
