Practical
Approximate: scaled from the numbered site marker on Big Blue Divers' printed dive-site map (2020), georeferenced against the OpenStreetMap outlines of Ste Anne, Moyenne and Ile Cachée; the map is schematic, so treat the pin as within roughly 0.5-1 km. Big Blue Divers site 43: 16-24 m, granite rocks with often a current, deep dive; stingrays, schooling eagle rays, moray eels, hump-head parrotfish, turtles, whitetip reef sharks, dolphins, wahoo and seasonal whale sharks. Open-sea site with no shelter. Dive with a licensed Seychelles centre (Big Blue Divers lists it as a long-distance boat trip from Beau Vallon); do not anchor a yacht on the rocks.
