Inside the sea caves of the Calanques

July 2026, at the helm of O2 Mer, in the Calanques between La Ciotat and Marseille. On the 5th, the boat runs along tall white limestone cliffs, right at the water's edge.

On the 6th, into a sea cave: the light from outside makes the water glow blue on the rock; seen from inside, the entrance opens like a slit of light onto the sea. The cave walls plunge straight into the water. The commentary is given in French, English or Spanish.
