Hiking Seoraksan National Park
Which trail, which month, and the two rules that turn visitors back
Seoraksan is where Korea's granite rears up into spires, knife-edge ridges and bare domes of rock, threaded by clear valleys and Buddhist temples. It has an easy valley walk for anyone and a scrambling ridge for the very experienced, and it is the first place in the country to turn red each autumn. The trick is to match the route to your fitness and the season rather than to the mountain's reputation, and to check what is open before you set out.
- Check the trail status that morning. High trails close for weeks at a time; the Korea National Park Service page is the authority.
- Start at dawn. Checkpoints turn walkers back after the entry cut-off, even with daylight left.
- Choose the route by your fitness. The valley walk suits anyone, Ulsanbawi the reasonably fit; the summit and the ridges are serious days.
- Carry crampons from December to February. You need them on the summit routes in winter.
- Sleep in Sokcho. Seoul is two and a half hours each way, and the good light is early.
How this page was madeWe have not yet been to South Korea, and we have not climbed here. This page is built from the Korea National Park Service's published rules, VisitKorea and detailed accounts by experienced hikers. Mountain information is safety-critical and changes with the season, so we date every closure and cut-off. When we go, we will say so here.

Why Seoraksan
Korea is roughly seventy per cent mountains, and hiking is close to a national pastime: you will share the trail with well-equipped Korean hikers of every age. Of all the national parks, Seoraksan is the one most often described as alpine. It sits on the Baekdudaegan, the mountain spine that runs the length of the peninsula, and its highest point, Daecheongbong, is 1,708 metres, the third-highest peak in South Korea.
It is also the first place in Korea to turn each autumn. For two or three weeks in October the maples catch fire against the rock, and much of the country seems to arrive at once. Come for the drama of the granite and the colour; come prepared for company.
The routes
Five options, from a cable-car stroll to an expert ridge scramble. Distances and times are round trip and approximate: your pace, the crowds and the conditions all move them.
| Route | Distance | Time | Difficulty | What it is | Suits |
|---|---|---|---|---|---|
| Gwongeumseong (cable car) | Short walk | Under 1 hr | Easy, no climb | Cable car from Sogongwon, then a rocky path to a fortress viewpoint | Anyone; long queues in foliage season |
| Biseondae and Cheonbuldong valley | ~5 km | 1½–2 hrs | Easy | A near-flat riverside walk from the entrance into a granite valley | First-timers and families |
| Ulsanbawi Rock | ~7.6 km | 3–4 hrs | Moderate to hard | Past Sinheungsa temple, then a long, steep, railed staircase to a granite crown | Reasonably fit walkers; the classic day |
| Daecheongbong summit (via Osaek) | ~12–16 km | 7–8 hrs | Strenuous | The 1,708 m peak by its shortest, steepest approach | Strong hikers with a dawn start |
| Gongnyong (Dinosaur) Ridge | 17–20 km | 10+ hrs | Expert only | Chains, ladders and scrambling along a knife-edge ridge | Experienced hikers, very early or with a shelter booking |
Strong hikers often combine the summit and the ridges, sometimes with a night in a mountain shelter. Only those overnights need a booking: day hikes need no reservation at all.
From what we have read, a reasonably fit first-timer should make Ulsanbawi the day, sleep in Sokcho the night before and start at dawn.
— Andrew + MargaretSeasons and closures
This is the part that catches visitors out. High trails close for weeks at a time for fire prevention, and the peak you travelled for may be shut. The lower valley walks stay open when the high routes close.
| Season | Months | Conditions and access |
|---|---|---|
| Spring | Mar–May | High trails closed for fire season: in 2026 roughly 4 March to 15 May, shutting Daecheongbong and the ridges. Lower valley walks stay open |
| Summer | Jun–Aug | Hot and humid, with the jangma rains in July and afternoon storms. Greener and quieter; start very early |
| Autumn | Sep–Nov | The season. First foliage in Korea, peak roughly 17–25 October, spectacular and extremely crowded. High trails close again from mid-November |
| Winter | Dec–Feb | Snow and ice; the summit's winter window has run roughly 16 December to 28 February. Crampons essential; short days, severe cold |
The October colour is the park at its best, but the high trails shut soon after. In 2024 and 2025 they closed from 15 November to 15 December. KNPS normally announces the new dates in early November, and had not done so for 2026 when we rechecked this one date on 3 October 2026. Check KNPS before you plan a late-season summit.
Getting there and where to stay
The mountain rises just behind Sokcho, an easy coastal city that makes the natural base. An express bus from the Seoul Express Bus Terminal takes around two and a half hours (roughly ₩17,000–22,000 by class). From Sokcho, local bus 7 or 7-1 runs to the main Sogongwon entrance in about thirty minutes for a little over ₩1,800; a taxi takes fifteen. For the southern Osaek trailhead, the short route up Daecheongbong, take a separate bus towards Yangyang.
Sokcho is the obvious base: a proper town with a well-known fish market, beaches and plenty of beds. Seorak-dong, at the park entrance, is handy for a dawn start and quieter in the evening. Osaek is a hot-spring hamlet on the southern side, at the foot of the short summit route.
The Gwongeumseong cable car is the one paid extra and the easy way to a high view. In peak foliage weeks the wait can run to a couple of hours and the car park fills by around 8am on a Saturday, so arrive early or come midweek. Confirm the fare and hours before relying on it.
Safety, kit and getting it wrong
Korean mountains are well marked and busy, which lulls people. Seoraksan is still a real mountain with real weather and enforced rules.
The long routes are the park's great days out, but KNPS enforces entry cut-offs at trail checkpoints, and rangers can turn you back with hours of daylight left. Broadly, entry opens around 03:00–04:00 in the warmer months and closes by early afternoon, earlier in autumn and winter. The times move with the season; we could not confirm them officially, so check them and start early.
Endless stone stairs and bare rock punish trainers and knees alike.
The weather turns quickly at altitude, even on a fine morning.
Supplies on the trail are limited, and the torch is your margin if you run late.
Crampons or microspikes are not optional on the summit routes from December to February.
Signal is patchy, so carry an offline map and a charged phone. The numbered trail-marker posts tell rescuers where you are.
The checkpoint turned you back. You arrived after the entry cut-off. It exists so people are not caught out after dark; start at or before dawn for any long route.
The trail you came for is closed. Fire closures shut the high routes for weeks. The valley walks and Ulsanbawi usually stay open, so have a lower-trail plan B and check KNPS before you travel.
The weather closed in on the ridge. Turn back. The ridges are exposed, chained scrambles that become dangerous wet or iced. In an emergency call 119 and give the nearest numbered marker post.
Sleeping on the mountain. Only multi-day routes need a booking, for the mountain shelters such as Huiungak at about 1,200 metres. You reserve them through the KNPS online system, which opens for Seoraksan on the 1st and 15th of each month for the following fortnight; a bunk is a modest fee paid at the shelter.
The wider parks: where Seoraksan fits
If Seoraksan is closed, too far or too hard for your trip, Korea's other great parks each answer a different need.
| Park | What it is for |
|---|---|
| Bukhansan | On Seoul's doorstep and beginner-friendly: granite peaks reachable by metro and bus for a half-day |
| Seoraksan | The dramatic one: spires, stairs and the ridges. The flagship, best in autumn |
| Jirisan | The oldest and largest park: a long high ridge crossed in one push or over several days with shelters |
| Hallasan | Korea's highest peak, 1,950 m, on Jeju: a long but non-technical summit day; summit routes need their own reservation |
| Naejangsan | Less about the summit, more about the colour: one of the country's best-known autumn-foliage parks |
A final word on Seoraksan
Seoraksan gives back exactly what you put into planning it. Pick the route your legs can manage, check what is open the morning you go, and be on the path at first light, and the most dramatic mountain in Korea is open to almost anyone.

Do I need to book a day hike?
No. Park entry is free and day hikes need no reservation. Only the mountain shelters, used on multi-day routes, need a KNPS booking.
Can I do Seoraksan as a day trip from Seoul?
You can, but it is about two and a half hours each way by express bus, plus the local bus to the entrance. An overnight in Sokcho lets you start at dawn, which matters for the checkpoints and the light.
Is the cable car worth it?
It is the easy way to a high view without climbing. In peak foliage weeks the queue can run to a couple of hours, so go early or midweek, and confirm the fare and hours first.
