Dive-site story
Located off the northern coast of Green Island, Grand Canyon features dramatic underwater volcanic architecture with deep ravines, towering vertical rock walls, and narrow swim-throughs. Strong oceanic currents fueled by the Kuroshio flow past the structural clefts, attracting pelagic visitors alongside dense colonies of seafans and soft corals clinging to the basalt formations.
Deep basalt rock fissures creating canyon-like corridors and overhangs
Large sea fans and whip corals populating the deeper vertical canyon walls
Frequent encounters with green sea turtles and patrolling pelagic hunters
