Grotte aux Dentelles: a coral-massif cave at Etang-Salé.
Grotte aux Dentelles is a shore-access coral-massif cave at Etang-Salé in La Réunion, with boat access also possible outside the bay. The small grotto cuts through a coral plateau marked by drop-offs and arches, making it a good place to slow down, hold trim and read the reef at close range. It suits buoyancy practice, relaxed reef circuits and fish watching more than depth chasing or current hunting.
