Three coral patches on sand off St François, lying between 15 and 25 m. Groupers and snappers hold on the coral, garden eels peek out of the sand, and a cleaning station in the east of the site draws a steady queue of fish at around 13 m.
Where it is and how deep
7.1157° S, 52.7534° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
The site is three separate coral patches sitting on open sand, between 15 and 25 m. Each patch is worth working around on its own, and the sand in between is not empty ground to cross quickly: garden eels stand out of it and fold away as you approach, so a slow, low approach sees far more of them than a direct swim.
The coral itself holds a variety of groupers and snappers, the resident fish that make each patch feel like a small self-contained reef. The eastern end of the site is where to finish. A cleaning station at around 13 m attracts yellowfin goatfish, blackspot and bluestripe snappers, and Napoleon wrasse, all queuing in shallower water than the rest of the dive — which makes it a convenient last stop rather than something you have to plan a second dive around.
