Îlot de Sable Blanc

Îlot de Sable Blanc is an islet that emerges during low tide in Mayotte's lagoon, displaying white sand beaches with surrounding coral reefs. The reefs sit at depths between 1 to 6 meters (3 to 20 feet), creating a natural barrier around the site.

The coral barrier surrounding the islet developed over millions of years, creating a protected zone within one of the world's largest lagoons. This geological formation shaped Mayotte's coastal landscape into its present form.

Local fishermen use traditional routes to reach the islet and share their knowledge of the sea with visitors. The seasonal weather patterns and tidal movements shape how people interact with this marine space.

Visiting the islet requires boat transportation from M'tsamoudou beach, with organized excursions providing equipment and meals for full-day trips. These outings need good swimming ability and comfort spending hours in shallow water.

The location hosts giant clams, blue sea stars, and table coral formations visible through the water. This marine variety turns each visit into a window onto an active underwater world.
