Cap St-Sébastien Dive Cruise — 8 days

8 days Diving On request Departures all year round — dates of your choosing

Our wildest dive cruise: a 70-mile sail to Cap St-Sébastien, to sites almost nobody dives. At the foot of the Mbamonetsimany cliffs, big corals host amberjacks, tuna, unicornfish and groupers; at Kalomisamba, two rocks joined by a cave concentrate sharks, turtles and trevallies.

The diving schedule is planned on site according to tides and currents — this is a true expedition, not a marked-out circuit.

Recommended season October to June, water 25–30°C, good visibility, depths from 15 to 40 metres. Divers must hold Open Water certification minimum.
