Most cities keep their national parks at arm’s length. Seoul does not. Bukhansan National Park wraps around the northern edge of the capital — granite ridges, dense pine forests, and a 2,000-year-old fortress wall sitting less than an hour from the city center by subway. If your Seoul itinerary has any breathing room, a day on these trails is worth it.
What Is Bukhansan?
Bukhansan National Park covers around 80km² of the northern Seoul metropolitan area, shared between Seoul and Gyeonggi Province. The park’s highest point is Baegundae Peak at 836m, part of a dramatic granite massif visible from much of the city on a clear day. Despite its compact size, Bukhansan consistently ranks among the most visited national parks per square kilometer anywhere in the world — on autumn weekends especially, trail bottlenecks near the summit are real. The park also contains Bukhansanseong, an 18th-century mountain fortress whose stone walls snake for over 8km along the ridgelines.
Top Hiking Routes
Baegundae Peak — The Summit Route
This is the main event. The Baegundae trail from the Bukhansan Ui entrance covers roughly 4.5km round trip and takes most hikers 3 to 4 hours. The lower portion is a well-maintained forest path; the upper section turns into open granite slabs where chains are bolted into the rock face to help you haul yourself up. The summit scramble is exposed and feels bigger than the elevation suggests. The payoff — a 360-degree view over the Han River basin, the city skyline, and the surrounding peaks — makes it worthwhile. Rated moderate to hard; not recommended in wet conditions.
Bukhansanseong Fortress Route
If the summit scramble sounds like too much, the fortress wall trail is an excellent alternative. The Bukhansanseong route follows the remains of the stone fortress — originally built during the Joseon Dynasty in 1711 — along a ridge with consistent views in both directions. The trail is easier underfoot than the Baegundae approach, though it still has real elevation gain. Historically interesting, photogenic, and significantly less crowded than the main peak trail on busy weekends.
Dobongsan — The Northern Peaks
Bukhansan’s northern neighbor, Dobongsan, is technically part of the same national park but accessed from a different subway station. The peaks here — Jaunbong, Mangwolsa, and others — offer sharp rocky ridge walks with slightly fewer crowds than Baegundae on peak days. The terrain is similarly rugged granite. A good option if you want the experience without the summit queue.
Getting There
Getting around Seoul by public transit is straightforward — read the full Seoul subway guide if you haven’t already.
- Baegundae / main Bukhansan area: Take Line 3 (Orange) to Gupabal Station, then catch Bus 704 or 34 to the Bukhansan Ui entrance. The bus ride adds about 15 minutes.
- Dobongsan area: Take Line 1 or Line 7 to Dobongsan Station. The trailhead is a short walk from the exit.
- From central Seoul: Allow about 45–60 minutes total travel time from major hubs like Gyeongbokgung or Hongdae.
What to Bring
- Hiking shoes: Non-negotiable. The granite is extremely slippery when wet, and trail runners without grip have caused more than a few accidents. Boots with ankle support are ideal for the summit route.
- Water: There are vending machines at the trailhead and a few points near the bottom, but nothing reliable higher up. Carry at least 1.5 liters per person.
- Light jacket: Temperature at the ridgeline drops noticeably compared to the city, and wind picks up near the summit. Even in summer, a packable layer is worth the weight.
- Cash: The mountain huts operate in cash. Bring some.
Food and Facilities on the Mountain
One of Bukhansan’s unexpected charms: mountain huts (sanjang) partway up the trails where you can stop for makgeolli (Korean rice wine) and pajeon (savory scallion pancake). It’s a deeply Korean hiking tradition, and the combination of cold makgeolli and hot pajeon after a hard climb is genuinely satisfying. Prices run around ₩5,000–8,000 per item as of early 2026 — verify before visiting. At the trailhead there are several small restaurants serving post-hike bibimbap, doenjang jjigae, and similar fare.
Best Times to Visit
Spring (April): Cherry blossoms line the lower paths, temperatures are mild, and the trails are at their most scenic. One of the best months to visit Seoul generally — the Han River is beautiful at this time too.
Autumn (October–November): Fall foliage turns the slopes orange and red. Peak autumn weekends are extremely busy — plan to arrive at opening time if you want a manageable experience.
Summer (June–August): The rainy season makes the granite dangerously slippery. Hike with extra caution or postpone until September. Heat and humidity are also significant factors.
Winter (December–February): Possible with proper gear. Crampons are recommended for the upper granite sections after snowfall. Some trails may be closed after heavy snow — check the national park website before heading out.
Bukhansan pairs well with broader Korea travel. If you enjoy mountain hiking, Seoraksan National Park near Sokcho offers a similar granite landscape on a much larger scale and is worth adding to your itinerary.
Practical Tips
- Start early: Gates open at sunrise. The summit trail gets congested by mid-morning on weekends. An early start means cooler temperatures and fewer bottlenecks at the chain sections.
- Sunset closures: All trails close at sunset. Rangers actively enforce this. Plan your descent with buffer time.
- Cell signal: Mostly reliable along the ridgelines and near the summit. Useful for navigation apps, though the main trails are well-marked.
- Entrance fee: Bukhansan National Park currently has no entry fee for most trails — confirm this is still the case before your visit as fees have been discussed periodically.
- Accommodation: Most hikers day-trip from Seoul. If you want to be close to the Dobong or Ui entrance the night before an early start, compare options on Trip.com for nearby neighborhoods like Suyu or Dobong.
Do I need to book a permit to hike Bukhansan?
No permit is required for standard hiking in Bukhansan National Park. You can simply show up at the trailhead. However, some restoration zones within the park have restricted access on a rotational basis — check the Korea National Park Service website (knps.or.kr) for current closures before your visit.
How difficult is the Baegundae summit trail?
Baegundae is rated moderate to hard. The trail itself is straightforward, but the final 200 meters involve scrambling on open granite slabs using fixed chains bolted into the rock. It requires upper body strength and a head for heights. Most reasonably fit adults can manage it, but it is not suitable for young children, people with vertigo, or anyone in street shoes.
What is the best subway station to start a Bukhansan hike?
For the main Baegundae summit trail, take Line 3 (Orange) to Gupabal Station and then take a local bus (704 or 34) to the Bukhansan Ui entrance — total travel around 15 minutes from the station. For the Dobongsan area on the northern side of the park, use Dobongsan Station on Line 1 or Line 7, which has the trailhead within easy walking distance.
Is Bukhansan worth visiting in winter?
Yes, but come prepared. The park stays open through winter and the granite peaks look dramatic with snow. You will need crampons for the upper sections after snowfall — rental is sometimes available at trailhead shops, but availability varies. Check trail conditions with the national park service before heading out, as some sections close after heavy snow for safety.
Can I hike Bukhansan without hiking boots?
Technically you can walk the lower trails in sturdy sneakers, but for anything above the mid-mountain area — and especially for the Baegundae summit route — proper hiking shoes with grip are strongly recommended. Wet granite is genuinely dangerous in smooth-soled footwear. Many of the accidents that occur on Bukhansan involve people underestimating how slippery the rock becomes after rain.
