Drift-style reef dive with a small cave and chances for larger pelagic sightings
Flat Rock - Turtle Cave is a northern Flat Rock dive with a small cave and reef terrain that drops away along the edge of the rock. It is best approached as a drift-style site where the main interest is the terrain rather than a fixed route. The site is reported as suitable for a wide range of diver experience, but current and overhead-environment awareness still matter. Pelagic encounters are part of the appeal, so divers should plan for moving water and open-water conditions.
