Ulsanbawi Rock Trail (Seoraksan National Park)

Ulsanbawi Rock is the granite mass that stands above the Sogongwon park entrance in Outer Seorak, and the Ulsanbawi Rock trail is the short walk up to the top of it. It is a completely separate objective from Daecheongbong, the summit of Seoraksan — much shorter, and easy for most of its length. The path runs past Sinheungsa Temple and Heundeulbawi, the Rocking Rock, on a gentle line, and then the final section climbs a steep steel staircase onto the rock itself. From the top you look down over Sokcho and the East Sea.

Quick answer — Ulsanbawi Rock is a single granite mass roughly 4 km around, above the Sogongwon park entrance in Outer Seorak, and it is the short alternative to a full day on Daecheongbong. The walk past Sinheungsa Temple and Heundeulbawi is easy; the last section onto the rock is a steep steel staircase, and that is the whole difficulty of the route. No reservation is needed and there is no entrance fee, but the Korea National Park Service does not publish an official distance, time or step count for this trail, so we do not quote one — call the park office on +82-33-801-0900 (checked 2026-08).
What this trail is, and what it is not
The Ulsanbawi Rock trail does not go to the summit of Seoraksan. Daecheongbong (1,708 m) is reached only from Osaek (5.0 km, 4h one way), from the Sogongwon park entrance up Cheonbuldong Valley (11.0 km, about 6h40) or from Hangyeryeong (8.3 km, 5h20). Ulsanbawi is a separate, far shorter objective on the Outer Seorak side, and for most visitors it is the better half-day. For the summit routes, entry times, closures and the cable car, see the full Seoraksan hiking guide.

What Ulsanbawi Rock is

Ulsanbawi is one piece of granite, roughly 4 km around, standing clear of the slope above the Sogongwon park entrance in Outer Seorak. From below it reads as a row of six rounded towers; from the side it is one wall. Its faces, along with those at Towangseong Falls, are where rock climbing in Korea began, and they are still used. Walkers do not touch any of that — the trail goes up the back of the formation on constructed steps.

It is the best-known thing in Seoraksan National Park after the summit itself, and the reason is access. From the park entrance you are on a path immediately, the walking is easy until the last section, and the reward at the top is a straight view over the coastal plain. That combination is why it is busy.

The route — Sinheungsa Temple, Heundeulbawi, then the staircase

The walk starts at the Sogongwon park entrance, on the Sokcho side of Seoraksan National Park, and goes first past Sinheungsa Temple. This is the working temple at the foot of Outer Seorak; the cultural property fee that used to be charged here — 4,500 KRW — was abolished in May 2023, so there is nothing to pay. From the temple the path continues on a gentle grade to Heundeulbawi, the Rocking Rock: a boulder balanced so that a group pushing it can visibly move it without shifting it off its base. Almost everyone who walks up here stops to try.

Up to that point the walking is easy and the path is wide. The difficulty is entirely in the final section, where the trail leaves the forest and climbs a steep steel staircase fixed to the rock, up to the top of Ulsanbawi. That is the part people remember, and it is the part that decides whether this walk suits you.

The Korea National Park Service does not publish an official distance, walking time or step count for the Ulsanbawi route in the sources we work from, so this page does not quote one — numbers you see elsewhere are other people's estimates. If you need exact figures for planning, ring the Seoraksan National Park Office on +82-33-801-0900.

What the staircase section is actually like

It is a sustained flight of open metal steps, bolted to the rock, climbing the last part of the formation. There is nothing technical about it — no scrambling, no hands on rock — but three things make it harder than the approach walk suggests. It is steep and continuous, so it is a leg and lung job rather than a stroll. It is exposed: the steps are open, with the drop visible through and beside them, which is a real problem if you do not like heights. And it is two-way on a narrow structure, so at busy times you spend as much energy waiting and passing as climbing.

In wet weather the steps are slippery and in winter they hold ice, which is the main reason to think twice about this section outside the dry months. If the staircase does not appeal, Heundeulbawi is a satisfying turnaround point in itself, and the Gwongeumseong cable car from the same park entrance gives a high viewpoint with no climbing at all.

The view from the top

From the top of Ulsanbawi Rock the whole of Sokcho and the East Sea lie below you, with the rest of Outer Seorak — ridges, spires and valleys — behind. It is one of the few places in the park where you get the mountains and the coast in the same view, and you get it after a fraction of the effort a summit day takes. Clear mornings are best; haze on the coast builds through the day in summer.

Crowding — and why autumn weekends are the worst of it

Seoraksan is normally the first mountain in South Korea to change colour — usually starting on Daecheongbong in late September and peaking in Cheonbuldong Valley in mid-October — and that makes October the busiest month on any mountain in the country. The Sogongwon car park fills before dawn in the foliage season, and Ulsanbawi takes a large share of the people who arrive, because it is the short walk everyone can do.

The pinch point is the staircase, where a queue forms and does not clear. If you are coming on an October weekend, come by bus rather than by car, and start as early as you can. A weekday in the same period is a completely different walk.

When to go

Spring
The one time Ulsanbawi has the mountain to itself. During the fire-prevention closure — 4 March to 15 May in 2026 — all 11 sections leading to Daecheongbong are shut, and the area around the Sogongwon park entrance, Ulsanbawi included, is effectively what remains open on this side.
Summer
Fine, but take rain gear: heavy rain closes valley trails in the park immediately, and the metal steps are slippery when wet. Start early to avoid the heat on the exposed rock.
Autumn
The best colour and the worst crowds. Late September to mid-October is peak on this mountain. Weekdays only, if you have the choice.
Winter
The staircase holds ice and Seoraksan closes trails for snow and wind at short notice. Carry crampons and check the closure information before you set out.
Late autumn
The second fire-prevention closure runs 15 November to 15 December in 2026, affecting the Daecheongbong routes. Check current notices for what is open on the Outer Seorak side before you travel.

Start times, cut-offs and closures

Seoraksan runs an entry-time designation system, and staff turn hikers back at control posts outside the window. The published times we can confirm cover the summit routes: Osaek to Daecheongbong, 03:00–12:00 from April to October and 04:00–11:00 in winter, and Biseondae to Yangpok, 03:00–14:00 in summer. We could not confirm a published cut-off for the Ulsanbawi route in the official sources we used, so we are not going to invent one. If you are planning a late start, call the park office on +82-33-801-0900 and ask before you drive out.

Reservation
Not required. Booking on Seoraksan applies only to the shelters (reservation.knps.or.kr, first-come) and the Gombaeryeong section on the Jeombongsan side, capped at 350 people a day.
Entrance fee
None. National park entrance fees were abolished in 2007 and the Sinheungsa Temple cultural property fee went in May 2023.
Parking
Park-run car parks, small vehicles: 4,000 KRW on weekdays, 5,000 KRW at weekends and in peak season (1 July – 31 August, 1 October – 15 November). The Sogongwon car park fills before dawn in October.
Closures
Fire prevention 4 March – 15 May and 15 November – 15 December in 2026 on the routes to Daecheongbong; Heullimgol separately 4 March – 15 April for rockfall. Weather closures at any time.

What to carry

Footwear
Proper hiking shoes with grip. The approach is easy underfoot, but the steel steps are a different surface and they are slick when wet.
Water
Carry your own — refill points on Seoraksan routes are few. Enough for the walk plus the wait on the staircase in season.
Layers
The top is open and windy even when the valley is still. Take a windproof layer whatever the forecast says.
Winter
Crampons for the iced steps, and gloves — you will be holding cold metal handrails.
Not needed
No reservation, no permit, no entrance fee. Bring money only for parking and for the cable car if you add it.

Getting to the park entrance

By bus

The base is Sokcho. Express buses run frequently from Dong Seoul Bus Terminal and the Express Bus Terminal at Gangnam in Seoul. From Sokcho, city buses #7 and #7-1 run to Seorakdong for the Sogongwon park entrance, which is where this walk starts (Korea Forest Service information). Check the timetable on the day, and note the last departure back before you start climbing.

By car

Set navigation to Seoraksan Sogongwon — not to "Seoraksan", which will send you to whichever trailhead the app prefers, and they are a long way apart. Parking is 4,000 KRW on weekdays and 5,000 KRW at weekends and in peak season for a small vehicle. In October the car park is full before first light, so the bus is the less frustrating option.

If the staircase is not for you — the cable car

From the same park entrance, the Gwongeumseong cable car climbs 1.128 km in about 5 minutes to Gwongeumseong Fortress at around 800 m — a viewpoint over Outer Seorak with no walking involved. It is 16,000 KRW return for adults and 12,000 KRW for children. There is no one-way ticket, no booking, and tickets are sold only on the day at the ticket office. Operating hours change daily with the weather and are posted each morning on the operator's site. Tel. +82-33-636-4300. It does not go anywhere near Daecheongbong.

Frequently asked questions

Q. Does the Ulsanbawi Rock trail reach the summit of Seoraksan?
No. Ulsanbawi Rock is a separate formation above the Sogongwon park entrance in Outer Seorak. The summit of Seoraksan is Daecheongbong at 1,708 m, and it is reached only from Osaek (5.0 km, 4 hours one way), from the park entrance up Cheonbuldong Valley (11.0 km, about 6h40) or from Hangyeryeong (8.3 km, 5h20). Ulsanbawi is a much shorter walk and is best treated as a half-day of its own.

Q. How long does the Ulsanbawi Rock trail take?
We cannot give you an official figure. The Korea National Park Service does not publish a distance, walking time or step count for this route in the sources we work from, and rather than repeat someone else's estimate we would rather say so. What we can tell you is the shape of the walk: an easy, gentle path from the park entrance past Sinheungsa Temple to Heundeulbawi, then one steep steel staircase to the top. For exact figures, call the Seoraksan National Park Office on +82-33-801-0900.

Q. Is the Ulsanbawi staircase difficult or scary?
It is not technical — no scrambling and nothing that needs hands on rock — but it is steep, continuous, and open, with the drop visible through and beside the steps. If heights bother you, that will matter more than the effort. It is also two-way on a narrow structure, so on busy days you queue. In rain the steps are slippery and in winter they hold ice. Heundeulbawi makes a good turnaround point if you decide against the last section, and the cable car from the same park entrance gives a high view with no climbing.

Q. Do I need a reservation or a ticket for Ulsanbawi?
No. There is no reservation system for this trail and no entrance fee — park entrance fees were abolished in 2007 and the Sinheungsa Temple cultural property fee was abolished in May 2023. Reservations on Seoraksan apply only to the shelters, booked first-come at reservation.knps.or.kr, and to the Gombaeryeong section on the Jeombongsan side of the park, which is capped at 350 people a day. Your only likely cost is parking: 4,000 KRW on weekdays, 5,000 KRW at weekends and in peak season.

Q. How do I get to the Ulsanbawi trailhead without a car?
Take an express bus to Sokcho from Dong Seoul Bus Terminal or the Express Bus Terminal at Gangnam, then city bus #7 or #7-1 from Sokcho to Seorakdong for the Sogongwon park entrance, where the walk starts. In October the bus is the better option regardless, because the car park fills before dawn during the foliage season. Check the timetable on the day and note the last bus back before you start climbing.
