Sèche Croissant sits in the lagoon off Îlot Maître and is known for a shallow coral garden with very calm water. It is a no-current site that works especially well for night dives, with plenty of reef fish and small life in the coral. Reports from the site mention nudibranchs, crustaceans, white-tip reef sharks, crocodilefish, and sleeping turtles at night. The easy lagoon profile makes it a straightforward dive rather than a technical one.
