Hallasan and the volcanic spine of Jeju
Published on 09/10/2026 at 19:46 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Hallasan rises from Jeju as a shield volcano and the highest mountain in South Korea. Its summit reaches 1,947 m (6,388 ft), and the mountain fills much of the island’s interior.
Hallasan’s volcanic profile and summit ground
The mountain is broad rather than steep, with long volcanic slopes and a summit crater that holds Baengnokdam, a crater lake. That combination of sweeping flanks and a high rim gives Hallasan a clear profile from across Jeju.
Hallasan is tied to the island’s volcanic landscape, and its lava-built form is part of what defines Jeju itself. The mountain is also associated with Hallasan National Park and the island’s protected natural areas.Hallasan’s summit
Hallasan in Jeju’s cultural landscape
The mountain has long been more than a geographic high point. It appears in the island’s identity as a mountain that dominates the horizon and anchors the view from Jeju’s roads and settled lowlands.
Gwaneumsa, a Buddhist temple on the mountain, adds a historical layer to the landscape. The site links Hallasan with Goryeo-period religious history and with later rebuilding in the early twentieth century.Hallasan National Park
Walking the mountain’s upper slopes
Hallasan’s trails move through changing vegetation bands, from lower forest to higher open ground. The summit area is a distinct volcanic basin, and the approach on foot is part of the mountain’s identity.
The mountain’s protected status reflects its geology, plant life and bird habitat. Jeju’s volcanic character is visible here in the ash-rich slopes, the crater form and the oreum cones scattered across the island.Jeju’s tallest mountain
Visiting Hallasan: what travellers from Western Europe should know
- Hallasan sits on Jeju, south of the Korean mainland, and the mountain is reached by road from Jeju City and Seogwipo. The park’s trails begin at several trailheads around the mountain.trailheads around the mountain
- The upper routes involve a long climb on volcanic ground. The summit area sits at high elevation, and the mountain’s slopes are exposed rather than sheltered.
- Hallasan is a national park as well as a mountain. Its protected landscape includes volcanic features, forested lower slopes and a crater at the top.
- Gwaneumsa Temple lies on the mountain and brings a Buddhist layer to the visit. The temple adds a historical site within the broader volcanic setting.
