Hallasan (1,947 m) is the volcano at the heart of Jeju Island and the highest mountain in South Korea. At the top lies Baengnokdam, a summit crater, and the island around it is dotted with hundreds of small volcanic cones called oreum. It is part of the Jeju Volcanic Island and Lava Tubes UNESCO World Natural Heritage Site.
Choosing a trail
- Seongpanak or Gwaneumsa — the two routes to the summit crater. Both need an advance reservation and take a full day.
- Yeongsil or Eorimok — shorter climbs to Witse-oreum, with cliffs, alpine meadows and sea views. A great choice for most visitors.
Good to know
Mountain weather is very different from the coast. In winter, crampons or microspikes are essential, and trails close in bad weather. Check the Hallasan National Park website before you go.
