Grotta dei Fantasmi
Another top site in the area is Grotta dei Fantasmi, the ghost cave. The entrance is only 7 meters but the dive is only a few tens of cm from the surface, present several air bubbles and tunnels. Completely of white limestone rock it is reminiscent, in part because of the excellent visibility, of cenotes in Central America.
