Cave diving can be done at Cueva Taina, a system of long, winding caves stretching 300 feet. Night dives and fresh water diving are also offered. Juan Dolio The house reefs in Juan Dolio offer great range in depths as well and visibility between up to 100 feet. Another draw to the area is Tanya V, a more recent wreck from 1999. Just an hour away from Juan Dolio lay some of the best diving and snorkeling sites off Catalina Island. The black coral and marine life is exceptional in the area with the possibility of seeing black tip sharks, hammerheads and big rays.
