Dive-site story
Named after the iconic jagged peaks of Mount Kumgang, this offshore granite reef off the Goseong coast features dramatic underwater rock spires and clefts. The granite monoliths are draped in thick carpets of pale plumose anemones, creating a stark, high-contrast landscape typical of the northern East Sea. Cold nutrient-rich currents sustain dense macro life and large temperate marine species among the rocky crevices.
Towering granite pinnacles blanketed by dense colonies of white plumose anemones
Frequent encounters with giant Pacific octopuses hiding in rocky overhangs and deep crevices
Classic East Sea cold-water topography featuring vertical walls, boulder fields, and swim-through channels
