Southwest Pinnacle
Sail Rock & Southwest Pinnacle · Thailand
Multi-peaked granite pinnacle rising from 30m sand to 5m, draped in anemones and black coral. Granite formations in circular pattern attract schools of fusiliers, snappers, and barracuda. Notable for giant groupers, stingrays in overhangs, and seasonal whale shark encounters. Strong currents common; visibility typically 15–30m.
