Anchor the boat at a point where the cliffs tower 400m over the sea. Follow a rocky, triangular shaft down to 28 meters. The entrance of this huge cave system looks like “the gate to the center of the earth.” The cavern zone is small compared to the rest of the system, yet the walls are adorned by hundreds of mussels and if you take a look, huge halls open up to a path that leads inland. It is a spectacular dive in the house of Neptune.
