Choizil Islets

The Choizil Islets are one of the finest sites in Mayotte: turquoise waters, banks of white sand, black rocks and green hills in the background. They are a few miles from the coast, and can only be reached by boat. The coral beds are relatively damaged, but abound in multi-colored fish (clownfish, angelfish, etc.).
How to get there?

The Choizil Islets are in the Mayotte lagoon, to the north-west of the island, some 3 miles (5km) from the coast. This is one of the most popular excursions in Mayotte, and you will have no trouble finding guides or fishermen to take you. The excursions to the Choizil Islets generally also include a stop at the Ilot de Sable Blanc du Nord, and sometimes one of the beaches on Mtsamboro Island. The sandbank generally only emerges at low tide. If you are organising your own trip, find out about tide times.

Water entrance

It is easy to get into the water from the white sandbank where you will land. The snorkeling spot extends all along the sandbank on the north-east coast, on the Mayotte side (the south-west side is more turbulent and exposed to waves).

Aerial view


The area to explore covers a width of about 300 feet (100m) along the white sandbank, on the Mayotte side.

Sand bank at Choizil Islets

The first dozen yards or so from the beach (↕6-10ft/2-3m) are made up of damaged coral. In places, new colonies are taking root. It is quite easy to come across several species of angelfish and surgeonfish. As you move away from the shore, the water level soon becomes deeper (↕10-20ft/3-6m). The large blocks of coral drop abruptly down to the sandy sea bed. Look for the impressive sea anemones, where many skunk clownfish can be found hiding. To see turtles, which are not common here, go to N'Gouja or Trois Baobabs, which are accessible from the coast.

Visibility on this spot, far from the coasts, is generally excellent and the waters are protected from the waves. But you should avoid the area at the far right of the islets, as you are facing the ocean, since the currents crossing it are sometimes strong. Follow the instructions of your guide, who will advise you on what to do according to the prevailing conditions.

Restaurants and accommodation

No food or water is available for purchase on the islands. The tour organisers generally provide meals and drinks – ask them for more details.
