About Grotte arc en ciel
Offshore cave dive off Marseille with vivid light effects, a compact underwater profile, and a route that suits confident intermediate divers and above. The appeal is the mix of rock, shadow, and sunlight inside the cavern, plus the life around the walls. Plan for a slow, controlled boat dive with careful buoyancy near the roof, a compact route, and a conservative turnaround if the local sea state is less settled.
