What it actually is
Hanyangdoseong, the Seoul City Wall, was originally built in the 14th century to encircle and defend the new Joseon capital, following the ridgelines of the mountains around the city center. Large sections survive and have been restored, forming a walkable trail that alternates between quiet mountain paths and stretches running directly through residential neighborhoods.
The best sections to actually walk
- Naksan section — the most central and easiest stretch, with skyline views and easy access from Daehangno; a good choice if you want a shorter taste of the wall without a full hike.
- Bugaksan section — a more demanding route near Bukchon with some of the best elevated views of the palace district, though it has required ID and specific entry hours in the past due to its proximity to the presidential residence area — confirm current access before planning around it.
- Inwangsan section — a rockier, more dramatic stretch near Seochon, popular with photographers for sunset.
Should you do it
Even a short section is worth it if you want elevated city views without committing to a full mountain hike like Bukhansan. The Naksan section specifically is genuinely approachable for most fitness levels and pairs naturally with a Jongno or Bukchon day.
Tip: Sections of the wall pass through quiet residential neighborhoods — keep noise down and be respectful of residents living directly alongside a major historic site.
