Dive-site story
Formed by ancient volcanic activity along the western coast of Réunion, Les Arches features imposing basalt rock arches, overhangs, and swim-throughs. Sunlight penetrates the overhead rock formations, illuminating patches of hard corals, gorgonians, and crevices sheltered from swell. Divers navigate through these natural passageways while watching for resident reef dwellers and pelagics cruising the blue.
Large volcanic basalt arches and swim-through tunnels
Sheltered overhangs hosting spiny lobsters and soldierfish
Frequent encounters with green sea turtles resting on the reef
