Shoulder
Shoulder: advanced Mafia Island drift with strong current
Local operator required
Boat access, strong currents, and tide timing make a local operator the practical way to dive Shoulder.
Shoulder is a tide-driven edge-of-bay reef where experienced divers plan for strong current, boat access, and a current-led drift.
About Shoulder
Shoulder is a demanding boat drift on the edge of Chole Bay in Mafia Island Marine Park, where strong tidal flow sweeps a sloping reef with hard and soft coral. It suits experienced divers who can time the tide and want a current-led run with big schools of sweetlips and emperors, plus groupers, rays, morays, and guitarfish.
