It is accessed thanks to a passage 8 meters deep that opens into a very large room, illuminated by a fantastic play of lights that penetrates through the cracks between the boulders. Inside you can find some plant species that make space by exploiting the sunlight coming from the surface. Entering this room it is possible to meet juvenile forms of many species of fish including: crabs (Coger conger) or moray eels (Muraena helena) that turn among the pebbles and the clouds of microscopic planktonic crustaceans. The wall to the right of the cave is full of cuts and crevices, providing a perfect shelter for many species such as juveniles of brown grouper (Ephinephelus marginatus). Ustica Academy Cave Dive is located in zone C of the Ustica Island Protected Marine Area.
