Hallasan Eorimok Trail: A No-Reservation Hike for Beginners
Yes, you can hike Hallasan on Jeju without a reservation by taking the Eorimok Trail. Unlike the summit routes (Seongpanak and Gwaneumsa), Eorimok does not need an online booking. It climbs from the northwest side of the mountain through forest to the open highland around Witse Oreum Shelter, roughly 4.7 km one way, and the longer full route continues to the Nambyeok (South Wall) junction. It does not reach the summit crater Baengnokdam, but it gives some of the best views on the mountain with far less planning, and bus 240 from Jeju City stops near the entrance.
This guide explains how the trail works, how to get there by bus, how hard it really is, and what to know about cut-off times and weather.
Why Eorimok is a good first Hallasan hike
- No reservation: just turn up within the permitted entry hours. This makes it ideal if you only decide on the day, or if summit slots are sold out.
- Shorter and easier: the summit routes are long, full-day climbs. Eorimok to Witse Oreum is a manageable half-day hike up and back for most reasonably fit visitors.
- Big views: after the forest section you come out onto a wide highland plateau with low shrubs, open sky and, on clear days, views of the summit's rocky south wall and the island below.
- Bus access: no car needed.
If your heart is set on standing at the crater, see our guide to Hallasan hiking reservations: Seongpanak vs Gwaneumsa. Eorimok is the better choice if you want views without the booking and the 8–9 hour day.
The route step by step
1. Eorimok trailhead to the forest climb
The trail starts near the Eorimok visitor area, where there is an information center, toilets and parking. The first part crosses a stream valley and then climbs steadily through dense broadleaf forest on stone steps and wooden stairs. This is the steepest and most tiring section; take it slowly.
2. Sajebi Hill and the open highland
After the forest, the trail reaches a broad hill area (Sajebi Dongsan) and the landscape opens up. From here the path becomes a gentler wooden boardwalk across the highland plains, with low dwarf bamboo and shrubs. On a clear day this is the highlight of the hike.
3. Witse Oreum Shelter
The boardwalk leads to Witse Oreum Shelter, around 4.7 km from the start. This is where most visitors turn around. There is a rest area and, on clear days, a close view of the summit's south wall. Many hikers count this as "Hallasan done" for a first trip.
4. Optional: Nambyeok junction
From Witse Oreum the trail continues toward the Nambyeok (South Wall) junction, which adds distance and time. This section has its own, earlier entry cut-off, so check the time at Witse Oreum before continuing. From the area you can also descend via the Yeongsil or Donnaeko trails instead of returning the same way, if you have planned your transport.
How long and how hard is it?
Most hikers take around 2 to 3 hours up to Witse Oreum and a bit less coming down, so plan on 4 to 5 hours for the return trip including rest. Published distances vary by source, so check the current figures on the official Hallasan National Park site. The trail is well maintained and signposted, but the forest section is a long, continuous climb. If you are used to walking but not to hiking, it will be challenging but doable at your own pace.
Getting there by bus
- Take bus 240 from Jeju Intercity Bus Terminal in Jeju City (it also stops at other points along the way). Get off at the Eorimok Entrance stop.
- From the stop it is roughly a 15–20 minute walk uphill to the actual trailhead.
- Buses are not very frequent, roughly hourly, so check the timetable and your return bus in KakaoMap or Naver Map before you set off.

Entry cut-off times and weather
Hallasan has seasonal entry cut-off times for each section. If you arrive at the trailhead or a junction after the cut-off, rangers will not let you continue. Times differ between winter, spring/autumn and summer, so check the current schedule on the official Hallasan National Park website on the day.
The weather on Hallasan can change quickly. It can be clear in Jeju City and foggy, windy or snowing on the plateau. Trails may be partly or fully closed after heavy rain, snow or strong winds. Check the park's trail status notice before you leave.
Winter hiking
In winter Eorimok becomes a popular snow hike, but the trail is icy. Bring crampons or microspikes (shops in Jeju City sell or rent them), warm layers, gloves and a hat, and expect earlier cut-off times.
"Witse Oreum on a clear day feels like the top of the island, even if it isn't the summit," says Jun, one of our POPORO CITY residents who prefers views to bragging rights.
What to bring
- Proper hiking or trail shoes
- Water and snacks (do not count on buying anything on the trail)
- Wind jacket and an extra warm layer, even in summer
- Rain gear
- Crampons in winter
- A bag to carry your rubbish down; there are no bins on the mountain
