The dive
The finest cave dive of the Egadi. Already at the entrance you see large groupers, shrimp and other crustaceans, so it is worth it even without going far in.
Profile and sections
The finest cave dive of the Egadi. Already at the entrance you see large groupers, shrimp and other crustaceans, so it is worth it even without going far in. Inside is a chamber like a Gothic cathedral, full of stalactites, stalagmites and encrusted columns from the time the cave was dry, with light beams through the clear water. 'Demanding but beautiful', wrote SUB magazine; in June 2020 the water on the bottom was 14–15 °C.
