What it actually is
Bukhansan National Park covers a range of granite peaks on Seoul's northern edge, easily reached by subway from central districts. Hiking here on a weekend is a genuine, widely shared local habit — expect to see hikers in full technical gear alongside casual visitors in sneakers.
Route difficulty varies a lot
Trails range from gentle, well-paved loops suitable for a casual visitor to genuinely steep granite scrambles near the summit ridges that require reasonable fitness and, in wet or icy conditions, caution. Baegundae, the highest peak, is a popular but strenuous target; there are considerably easier routes if you just want mountain views and forest without the full summit push.
The fortress wall
Part of the historic Bukhansanseong fortress wall runs through the park, adding a layer of history to the hike beyond just scenery — sections of restored wall are visible along several of the main routes.
Practicalities
- Trailheads are reachable via subway plus a short bus or walk — Gupabal and Suyu stations are common access points.
- Proper footwear matters more here than almost anywhere else on a Seoul itinerary — some of the granite sections are steep and can be slick.
- Weekends get genuinely crowded on the popular routes; a weekday hike is a very different, quieter experience.
