Grotte Aux Dentelles

Grotte aux Dentelles is a coastal dive site near Saint-Leu on Réunion Island. The site is characterised by a canyon-like swim-through and rocky formations that create multiple arches and vertical walls. Entry is typically from shore or a short shore-based ascent, with currents generally mild and visibility often variable depending on conditions. Expect macro life typical of tropical Indian Ocean sites, with nudibranchs, small reef fish, and intermittent larger species around the rocky structure. The surrounding reef topography provides interesting navigation through the limestone ridges and dentelle-like formations, making it a good choice for drift or entry-level to intermediate divers depending on current and surge. Access from the nearby towns of Saint-Leu and L’Étang-Salé makes this a convenient local option for a day’s dive.
