Someorioreum Volcanic Cone (Udobong Peak)

This guide to Someorioreum, Udobong Peak on Jeju's Udo island, traces how an undersea volcanic eruption built the grass-covered cone beneath your feet, and how sailors once read the whole island's shape as a cow lying in the water. It follows the view from the summit across to the tuff cone of Seongsan Ilchulbong and Halla Mountain, and the short black-sand beach at its base. You'll hear how the peak got its name from that old comparison. Take the paved path to the top for the widest view of the coast.
