Tiboulen de Maire is a sheltered Marseille boat dive with a tunnel.
A local Marseille boat operator is the practical way to reach the cove and time the tunnel in calm conditions.
Tiboulen de Maire is a sheltered Marseille cove dive on the west side of the islet, with easy boat mooring and a rocky line that rewards calm-water timing. The route runs from the mooring along boulders and a shallow tunnel before easing into a deeper outer slope, so the site offers a clear progression from easy navigation to richer rock life. It is a good re-adaptation dive for beginners, photo work, and relaxed exploration when the sea is quiet.

Key Hazards
Safety Notes
Treat the tunnel as an overhead feature and keep the dive to quiet sea states. The outer slope is rockier and deeper than the entry cove.
Access Restrictions
Boat access and calm-sea conditions matter; the tunnel should only be approached when the sea is quiet.
Legal Notes
Mooring and diving are regulated in the Marseille calanques area, so operators need to follow local restrictions.
