Dive-site story
Located off the northern coast of Bangka Island in North Sulawesi, Batu Gosoh features a dramatic seascape of volcanic stone spires that rise from the seabed. Sheer drop-offs, crevices, and canyon-like swim-throughs are heavily cloaked in vibrant soft corals and massive sea fans. The site sits exposed to open sea, channeling currents that fuel dense marine life and bring in passing pelagic species.
Striking volcanic pinnacles and sheer underwater rock walls
Dense carpets of soft tree corals and large gorgonian fans
Frequent action from schooling jacks, snappers, and reef sharks
