The Ilots Choizil 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, including clownfish and angelfish.

How to get to Ilots Choizil snorkeling area?

The Ilots Choizil are located in the Mayotte lagoon, to the north-west of the island, some 3 miles off 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 Ilots Choizil 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 organizing your own trip, find out about tide times.

Entering the water at Ilots Choizil

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).

Snorkeling tips to enjoy the best of Ilots Choizil

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

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.

Regal angelfish at the Choizil Islets

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 main island’s coast.

Corals at Ilot de Sable Blanc

Underwater 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.
