Seoul pulled in more than eight million international visitors in the first half of 2026, most of them chasing K-pop, K-drama and K-beauty. But there's a quieter side to the capital that many travellers miss entirely: it's a city ringed by mountains, with maintained hiking trails you can reach by metro.
Hiking here is a genuine year-round culture, not a fair-weather hobby. Locals head out in rain and snow in full kit, and the trails are unusually well serviced — public restrooms, picnic spots, outdoor gyms, and even shoe-cleaning stations at the end of a muddy climb. In hot, humid summer, several popular routes stay lit after dark, so night hiking becomes a cooler option with the city sprawled below you.
The classic intro hike is Namsan, the mountain at Seoul's centre topped by N Seoul Tower. Wooden staircases handle the steeper sections, and the route follows parts of the old city wall — worth a stop at the free Seoul City Wall Museum along the way.
For gentler walks, the Hongjecheon Stream path runs past forsythia and a waterfall before climbing Ansan. Art lovers should try Ihwa Mural Village, where painted murals cover the steep lanes — plenty of cafés provide excuses to catch your breath — and from there you can follow the wall down towards the Dongdaemun shopping district, ideally timed for golden hour.
Spring is peak season for colour beyond the usual cherry blossoms. Eungbongsan Mountain and Dalmaji Hill turn yellow with Korean forsythia, with views over the Han River towards Apgujeong. In April, Cheonggyesan on Gangnam's outskirts gets blanketed in pink azaleas, with Lotte World Tower visible in the distance and the small Cheonggyesa Temple to visit on the way down.
If you want a mission rather than a stroll, Seoul runs stamp-collecting routes with certificates at the end. The easiest for a short stay is the Seoul City Wall Trail: grab a map at Sungnyemun Gate or a tourist information centre, then walk sections across Namsan and Bugaksan, the latter rewarding you with views over the central palaces and Gwanghwamun Square.
Logistically, this is about as easy as urban hiking gets. Selected hiking centres rent out equipment, with changing rooms and showers, so there's no need to pack boots or gear. If you've got a full day, take the metro or bus north to Bukhansan National Park or Suraksan, where you can pick between easy forest paths and proper climbs with big views over the city's quieter northern districts.
This suits travellers who've done the palaces and the shopping and want something active that still fits inside a city break. Comfortable shoes are genuinely the only requirement — and, if you're collecting stamps, a bit of space on your camera roll.
