Boat-based Marseille dive with canyon and rocky terrain.
Boat access and local site knowledge are the practical route here, especially because the Riou area is tightly regulated.
Cap jarront is a boat-based Mediterranean dive off the Riou and Jarre side of the Marseille archipelago, with a rocky canyon and blocky terrain that reward slow exploration. It is best when the sea is calm enough for a straightforward crossing and a relaxed entry. Divers come for clear water, moderate currents, and a mix of Mediterranean fish and rock life around the canyon and sheltered blocks.

Access Restrictions
