Tour du Petit Ilet is a coral-rich wall tour around a small islet in the Cousteau Reserve, with a drop-off that lets divers choose shallower or deeper routes. The site combines reef structure, sea fans, and a wide mix of Caribbean marine life, making it appealing to divers who want a scenic wall without an especially technical entry. It works well as a guided boat dive with enough depth range to suit both cautious and more adventurous profiles.
