About Cave Island
Cave Island is a Pserimos boat dive built around a shallow cave, a sand patch, and a steep outer drop-off. The route is a loop around the island, so it suits divers who like a clear plan and a mix of cave, wall, and open-water terrain. It is more of a structured scenic dive than a casual shoreline visit.
