Dive-site story
Rising off the southern coast of Jeju Island near Seogwipo, Oedolgae is a towering volcanic sea stack whose surrounding waters showcase a blend of temperate and subtropical marine ecology. Submerged basalt boulders and dramatic drop-offs create an intricate terrain shaped by ancient volcanic activity. Colorful soft corals blanket the rock walls, sustained by the warm Kuroshio branch current flowing through the region.
