Oedolgae Rock, 20 meters in height, is the first thing that you will see when you look at the rocks surrounding Namju’s Haegeumgang River and the Seogwipo Chilshipri Coast. About 2 km away to the west of Seogwipo City there is Sammaebong Parsitic Volcano and Oedolgae Rock, which stands on a beautiful shore near the mountain, and was formed when a volcano erupted and changed the island’s landscape about 150,000 years ago. Since it is a strong rock carved by wave erosion, it is called a sea stack. At the peak of the island, there are pine trees that are regenerating.
