Bukhansan (북한산) is a national park on the northern edge of Seoul, built on dramatic granite peaks. Its highest point, Baegundae Peak, is 836 m, and on a clear day the summit looks out over the whole city. Because the trailheads sit right next to the subway network, "hiking a real mountain on a half-day trip from downtown" has become one of the most popular things for foreign travellers to do in Seoul. There is no national park entrance fee.
1. Getting there
From central Seoul (Myeongdong, Hongdae, etc.) the trailheads are about 1 hour away by subway and bus. Pick your trailhead first, because the two main gateways are on opposite sides of the mountain.
East — Ui-dong side
- Ui Line (우이신설선) → Bukhansan Ui Station (북한산우이역)
- Walk ~20 min through Ui-dong to the Baegundae trailhead (or a short taxi)
- Closest to the gear-rental centre (Exit 2, 5 min)
West — Bukhansanseong side
- Line 3 → Gupabal Station (구파발역), Exit 1 or 2
- Transfer to bus 704 or 34 → "Bukhansanseong Entrance" stop
- Starts at the fortress gate; restaurant street right at the entrance
2. Course comparison
Times are a rough round-trip guide for an average hiker and vary with weather, crowds and rest stops.
| Course | Access | Round trip | Level | Notes |
|---|---|---|---|---|
| Baegundae via Ui-dong (Doseonsa) | Bukhansan Ui Station → 20 min walk | ~2.5–3.5 hr (~2.6 km each way) | Moderate | Shortest way to the summit. Final ~300 m is rock steps with fixed steel cables. |
| Baegundae via Bukhansanseong | Gupabal Station → bus 704 / 34 | ~4–5 hr (~4–5 km each way) | Moderate–Hard | Follows the historic fortress wall past Daeseomun gate; wider views, more stairs. |
| Bukhansan Dulle-gil | Various section entrances (Ui-dong, Jeongneung…) | ~1.5–2.5 hr per section | Easy | 71.5 km low foothill loop in 21 sections — a flat forest walk, no summit. Section 21 (Uiryeong-gil) needs an advance reservation. |
New to hiking or short on time? Start with a Dulle-gil section. Want the summit photo? The Ui-dong route is the most direct.

4. After the hike: makgeolli & pajeon
In Korea, coming down the mountain and sitting down to pajeon — a sizzling savoury pancake, most often haemul-pajeon (seafood) or kimchi-jeon — with a bowl of cloudy makgeolli rice wine is as much part of the day as the climb itself. The pairing spread widely on social media and is now something many visitors plan their hike around. You'll find clusters of these restaurants right at the Bukhansanseong entrance on the west side and around Ui-dong on the east. Other common options nearby are dotori-muk (acorn jelly), doenjang-jjigae (soybean stew) and grilled pork.
5. Safety & etiquette
- Start early, be off the summit before dark. Each trailhead has posted entry cut-off times that change by season.
- Check closures first. Sections close during the dry spring/autumn fire-risk periods and when icy. Live status: bukhansan.knps.or.kr.
- Winter needs crampons. Bring gloves for the cable section near the top year-round.
- Carry 1 L+ of water and wear grippy hiking shoes; there are few shops once you're on the trail.
- Stay on marked trails. No cooking, no smoking, and don't climb after drinking. Carry your rubbish back out.
- If you get into trouble, note the nearest numbered location marker and call 119. Best months: April–May and September–early November (autumn weekends are very busy).
FAQ
How long does it take to reach Bukhansan from central Seoul?
About one hour from areas such as Myeongdong or Hongdae by subway plus bus. For the eastern trailheads, take the Ui Line to Bukhansan Ui Station; for the western Bukhansanseong entrance, take Line 3 to Gupabal Station and transfer to bus 704 or 34.
I don't have hiking gear. Can I rent it?
Yes. The Seoul Hiking Tourism Center, a 5-minute walk from Exit 2 of Bukhansan Ui Station, lends hiking shoes, trekking poles, jackets and other gear to foreign visitors for free or a small fee. It is open 09:00-18:00 and closed on Mondays; reserving ahead at seoulhiking.or.kr helps secure your size.
Can a beginner reach Baegundae Peak?
It is possible with average fitness, but the final stretch of roughly 300 metres is an exposed rock section climbed with fixed steel cables. A round trip takes about 2.5 to 5 hours depending on the route. If you are unsure, the Dulle-gil trail or turning back at a mid-point is a safer choice.
Is there an entrance fee?
There is no national park entrance fee for Bukhansan. Gear rental, transport and meals are separate costs.
Can I hike Bukhansan in winter?
Yes, but crampons are essential because of ice, and some sections may be closed. Check closure information at bukhansan.knps.or.kr before you set out.
What should I do after coming down?
Enjoying pajeon (savoury pancake, such as seafood or kimchi) with makgeolli rice wine at the restaurants by the trailhead is a classic Korean post-hike tradition. Restaurants are clustered near the Bukhansanseong entrance and around Ui-dong.
