Hallasan
Jeju's volcano — trails for every level.
Why go
Hallasan is a shield volcano at the center of Jeju and the highest mountain in South Korea, ringed by trails through changing forest and alpine scenery.
Some summit trails require an early start and reservations.
At 1,947 m, Hallasan is South Korea's highest peak — a dormant shield volcano crowned by the Baengnokdam crater lake and ringed by a UNESCO Biosphere Reserve that shifts from broadleaf forest to alpine shrubs, with royal azaleas in spring.

Good to know
- Check which trails reach the summit and whether reservations are needed.
- Weather changes fast — bring layers.
- Start early to finish within park hours.
- Only the Seongpanak and Gwaneumsa trails reach the summit — both long full-day hikes that need an advance reservation. The shorter Yeongsil and Eorimok trails give big views without the summit push.
