Ilot Choizil is a small islet in the lagoon of southeastern Mayotte, the French overseas department in the Indian Ocean between Madagascar and the African mainland. The snorkeling day trip is reached by boat from Bandrélé or Kani-Keli on the southern coast of Grande-Terre, with a crossing of about 30 to 40 minutes. Visitors travel by organized boat excursion or private charter, and the trip works best as a full day because it combines the crossing, long swimming sessions and a relaxed lunch ashore.
The appeal of the outing is the lagoon itself. Mayotte is surrounded by one of the largest enclosed lagoons in the world, ringed by a double barrier reef, and the southern waters near the islet offer clear conditions for snorkeling in the dry season. Snorkelers commonly see colorful reef fish, coral formations and green turtles grazing on seagrass. The sandy shoreline of the islet is suited to swimming, resting in the shade and picnicking between water sessions.
A typical day begins with a morning meeting at the departure point in Bandrélé or Kani-Keli, followed by the boat transfer across the lagoon. The first snorkeling stop is usually made in the morning, when the water is calmest and visibility is at its best. After lunch on or near the islet, a second swim and some free time on the beach fill the early afternoon. The boat returns in the mid to late afternoon, leaving enough daylight for the drive back toward Mamoudzou along the main southern road.
The best season is April to November, when visibility is highest and the seas are calmer. Between December and March the rains and swell can reduce water clarity and lead operators to cancel departures. Arriving early gives the best light underwater and avoids the hottest part of the day.
Food options on the islet itself are limited, so many excursions include a picnic or grilled fish lunch, and visitors should confirm this when booking. Otherwise, bring water, fruit and snacks purchased in Bandrélé or Kani-Keli. A few small local eateries on the southern coast serve grilled fish, rice and cassava, and are a good place to eat before or after the trip. Travelers without a car should arrange transport to the departure village in advance, since public taxis are infrequent in the south.
