Best for advanced divers, 17-25m, boat entry, strong current.
South Mariane Island is a complex site featuring a mix of reef, pinnacle, and canyon topography. Divers navigate depths between 17 and 25 metres, with an average depth of 19 metres. The site is strictly for advanced divers due to strong, variable currents and the presence of overhead environments within the canyons and swim-throughs. Visibility typically ranges from 15 to 30 metres. Access is by boat only, and guided tours are available. Divers should be aware of sharks at this location and must carry a surface marker buoy, as pick-ups often drift away from the entry point. Always confirm a drift-exit plan with your guide before descending.
