Hallasan, Korea: First-Timer's Guide to Hiking the Summit

Every country has a highest point that locals treat as a rite of passage. In Korea, it is Hallasan — a 1,947-metre shield volcano standing at the center of Jeju Island, crowned by the crater lake Baengnokdam and listed as part of the UNESCO World Heritage site "Jeju Volcanic Island and Lava Tubes" (inscribed 2007). It is not a technical climb. But it is not a casual walk either: the summit trails require an advance reservation, a start well before dawn, and — from October through March — strict respect for winter cut-off times. This guide covers what a first-timer actually needs to know.

Two routes reach the summit

Of Hallasan's five official trails, only two go to the top. The others end at high ridges and are fine half-day walks, but the crater lake is reserved for those who commit to one of these:

Seongpanak Trail (9.6 km one way, about 4.5 hours up). The standard choice for first-timers. It is the longest of the two, but the gradient is gentler, much of it running through forest on boardwalks. Allow roughly nine hours for the round trip.

Gwaneumsa Trail (8.7 km one way, about 5 hours up). Shorter and steeper, with long stair sections and rock underfoot — the pick for stronger legs. Expect nine to ten hours round trip. Note: the trail's upper section, from Samgakbong to the summit, reopened in late September 2026 after rockfall-safety repairs, so both summit routes are currently open.

If the summit feels like too much, the Eorimok (6.8 km to Witse Oreum, about 2 hours) and Yeongsil (5.8 km to the Nambyeok junction, about 2.5 hours) courses offer high-mountain air without the reservation or the full-day commitment. They do not reach Baengnokdam.

The reservation is the real gatekeeper

Entry to the Seongpanak and Gwaneumsa trails is by advance reservation only, through the official Hallasan trail reservation system at visithalla.jeju.go.kr. The reservation itself is free — as is park entry, since Korea abolished national park entrance fees nationwide in 2007.

Daily caps are strict: 1,000 hikers for Seongpanak and 500 for Gwaneumsa. Autumn weekends fill quickly, so book as early as the system allows. Without a reservation, you will be turned away at the trailhead — no exceptions, no standby line worth counting on.

Winter rules are already in effect

Hallasan runs on a winter schedule from October 1, 2026 through March 31, 2027, announced by the park office in late September 2026. All trails open for entry at 5:00 a.m., but the cut-offs are early and enforced:

• Entry cut-off: 11:30 a.m. for Seongpanak and Gwaneumsa; 12:00 noon for Eorimok and Yeongsil; 10:00 a.m. for Donnaeko.
• Descent deadlines: off the summit ridge (Baengnokdam east ridge) by 1:30 p.m.; Jindallaebat and Samgakbong shelters by 3:30 p.m.; Witse Oreum by 3:00 p.m.; Nambyeok junction by 2:00 p.m.

This is why the early start is non-negotiable: a 4.5-hour ascent means leaving the trailhead not long after it opens. Pack for winter above the tree line even in October — warm layers, traction aids, spare clothes, warm water, and emergency food are the park's own recommended kit. Check the Hallasan National Park website for weather and trail control notices before you leave; routes can be partially or fully closed in severe weather.

When the mountain turns

Hallasan is one of Korea's last major peaks to color each autumn. For 2026, the Korea Forest Service and National Arboretum forecast (published September 22, 2026) puts Hallasan's foliage peak at November 6, using their 50%-coloration criterion. The private forecaster Weather Eye, which uses an 80%-coloration definition, calls first color around October 31 and peak around November 13. The definitions differ, but the message converges: plan for the first two weeks of November.

Getting to the trailhead

The Seongpanak trailhead is the easiest to reach by public transport, with regular buses from Jeju City (routes 181 and 281) and from Jeju Airport. From Seogwipo in the south, the reliable routing goes via Jeju City. Bus schedules change with the season, so confirm current timetables on the official Jeju bus information site before your hiking day.

There are no shops along the trails — carry all water, snacks, and layers from the start, and carry all trash back out. Drinking, smoking, and open flames are prohibited in the park, and hikers must stay on designated trails.

Walk it your way

Hallasan rewards preparation more than fitness. Reserve early, start at dawn, respect the cut-offs, and the crater lake is yours.
