Protected bay reef with easy access and calm water.
Secret Harbor - South is a calm bay reef at the southwest corner of Secret Harbour, with easy beach access or a short boat hop to a shallow coral line. The route is simple and open, with cleaning stations, sand patches, and an easy finish toward the outer reef, so it suits snorkelers and divers who want a low-stress look at reef life, turtles, and occasional rays.
Safety Notes
Keep an eye on your exit if you start from the beach, and avoid standing on the reef when the water is shallow.
Access Restrictions
Unguided shore dives are possible; guided shore dives and boat dives should be booked through the resort or operator.
Legal Notes
Follow resort access rules, avoid touching coral, and use reef-safe buoyancy and finning.
