Daepo Jusangjeolli Cliff
Daepo Jusangjeolli Cliff is a stretch of coast near Jungmun, in Seogwipo on Jeju's south coast, lined with hexagonal basalt columns up to about 25 metres high. They formed when lava from Hallasan cooled quickly in the sea; a boardwalk along the clifftop looks down on the columns and the surf.
