Seongneol Oreum Volcanic Cone (Seongpanak)

Seongneol Oreum Volcanic Cone (Seongpanak) is a parasitic cone standing 1,215m high, located on the eastern slope of Hallasan. Its summit consists of a northern main peak and southern and southeastern peaks. It is named Seongneol Oreum because the vertical cliffs on the southeastern slope look like stacked planks used to build a fortress, and its entire slope is covered in lush forests. Located near the Seongpanak hiking trail within Hallasan National Park, the area features Seongneol Waterfall—famous as a refreshing spot—and various valleys.
