Overview
The cave is considered the biggest marine cave in the Mediterranean Sea. With the around 10 entrances, arches and tunnels, it is possible to make dives from 0 to 35 m, through long and large tunnels, air chambers and different ways. The walls are covered with red coral and yellow leptosamnia.
With the other cape of Punta Giglio and the Porto Conte Bay, the cave is part of a Marine reserve set up in 2003. Its flora and fauna are typically Mediterranean including groupers, lobsters, congers and moray eels, and thriving crustacean life.
