Iconic Martinique volcanic boat dive with arches and walls.
Diamond Rock is one of Martinique's signature boat dives, built around volcanic walls, arches, tunnels, and plateaus wrapped around the base of the rock. The site can be spectacular and varied, but it is not a casual sightseeing reef: route choice, exposure, and depth all matter if divers want to move safely between the shallows, the faille, and the deeper structure.
