Shark Bank

Shark Bank is Mahé's big-fish dive: a granite rise far enough offshore that everything on it comes in extra size. Marbled rays the width of car hoods rest between the boulders, yellow snapper and big-eye trevally form permanent walls over the plateau, and barracuda hang up-current in the ranks. The name overpromises on sharks these days — whitetips and the odd passing whale shark in season, not reliable schools — but the site's mass of fish, granite architecture, and open-water character keep it at the top of the island's list. Current and the deep, referenceless descent make it an advanced trip.
