More ways to explore the area's outdoor wonders
A salty wind pushes across low grass as you approach Seongsan Ilchulbong at first light; the cone rises like a fractured crown from the sea and the crater yawns with a flattened bowl that holds the island’s story. Walking its rim, you feel the cliff’s edge tug at your attention and the ocean insistently pull at the horizon.

History
Seongsan Ilchulbong formed from a single explosive eruption that breached the ocean surface; Manjanggul records long pahoehoe flows from Geomunoreum’s eruptions—both are central to Jeju’s volcanic legacy.
Conservation
Jeju’s UNESCO designation encourages trail maintenance and limits on development; visitors are asked to stay on paths and avoid collecting geological specimens.
