Key Dive Site Facts
Dive Site Overview
The dramatic formations of Oedolgae date back approximately 150,000 years, sculpted by ancient volcanic activity that profoundly shaped the island's coastal landscape. This impressive sea stack, reaching 20 m (65 ft) in height, stands as a testament to persistent wave erosion, which has carved its distinct shape into the ocean.
Underwater, the sea floor gradually slopes, stretching out in an S-shape parallel to the coastline, characterized by a series of deformed super-large rocks. Diving here is exclusively conducted by boat, allowing access to the deeper sections, which can extend to a maximum depth of 28 m (91 ft). Along the bedrock surfaces, divers can observe various soft corals, including cockscomb, long-branched pine, and white pine, contributing to the site's biological appeal.
Local legends also imbue the rock with historical significance, from tales of a transformed grandfather and an 'Angel Rock' to its role as 'General Rock' during a Goryeo Dynasty battle.
