This dive site, Plage des Roches Noires, is the main and iconic beach of Saint-Gilles, Réunion Island’s primary seaside resort. It serves as a shallow, protected snorkeling area, strictly regulated for use only when there is no ocean swell, and always confined within a designated shark net. The site offers a simple beach entry with no complex navigation or significant historical context for diving.
Within this small, confined area, snorkelers can observe a limited variety of marine life. Commonly sighted fish species include triggerfish, butterflyfish, surgeonfish, and sole. The description does not indicate the presence of extensive coral formations or diverse underwater flora.
The optimal time to visit this spot is during periods of calm sea, specifically when there is no ocean swell, as this is the only condition under which snorkeling is permitted. While not a destination worth a special trip for its marine attractions, it provides a pleasant, convenient activity for those already staying in Saint-Gilles. It is suitable for beginners and casual snorkelers.
