    CharacterCave dive
    StandoutExceptional marine biodiversity

    Riou's coral cave is a distinctive dive in the Marseille archipelago. The main attraction here is the cavern itself, home to some vibrant red gorgonian corals. It's a relatively easy penetration for divers comfortable in overhead environments, offering a different kind of Mediterranean experience away from the open reef. We'd suggest this one for divers looking for something a bit unique in the region.

    Safety Notes

    Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
