La Possession centres on Cap La Houssaye, where a compact collection of dive sites ranges from shallow beginner reefs to a serious deep wall. Grande Chaloupe, Vieux Roches and Petite Chaloupe offer sheltered, accessible reef diving, while Trois Bacs combines reef, wall, pinnacle and drift in a single outing. Grand tombant de La Possession drops into truly deep water, reserved for experienced divers. The species list is rich in cryptic and characterful life: Robust Ghost Pipefish, Giant Frogfish, Spanish Dancer and Peacock Mantis Shrimp are consistently observed across sites.

The shallow reef sites around Cap La Houssaye share a similar profile but each has its own texture: Trois Bacs stands out for combining reef, wall, pinnacle and drift topography in one dive.

Beginners and experienced divers therefore have distinct options within the same area.
