Hiking Gwanaksan Mountain: Rocky Peaks, Yeonjuam Hermitage and Access Paths

The rocky summit terrain

Gwanaksan is known among Seoul's hiking mountains for its craggy, exposed granite peaks, offering a rockier and more physically engaging climb than gentler options like Achasan. The terrain near the summit involves some scrambling over rock faces, making it better suited to hikers with at least some prior experience.

Yeonjuam hermitage

Yeonjuam, a small Buddhist hermitage built directly into the mountain's rock face near the summit, is one of Gwanaksan's most distinctive features, offering both a cultural stop and a dramatic photo opportunity along the route. Reaching it typically requires a short additional climb from the main trail, worth the detour for the setting alone.

Access paths and route choice

• Gwanaksan has multiple trailheads, with routes from the Seoul National University side and the Gwacheon side both commonly used.
• Trail difficulty varies noticeably by route, so checking which trailhead matches your fitness level before committing is worthwhile.
• The mountain straddles the Seoul-Gwacheon border, so trail signage may shift between Korean-only and bilingual depending on which section you're on.

Because of its more demanding terrain, Gwanaksan tends to attract a slightly more serious hiking crowd than some of Seoul's gentler mountains, and weekend mornings can see a steady stream of local hikers on the main trails. Bringing enough water is particularly important here given the more strenuous nature of the climb, since there are fewer facilities along the rockier upper sections compared to more developed trails elsewhere in the city. The summit views, taking in a wide stretch of southern Seoul and neighboring Gwacheon, are frequently cited as among the best rewards for the climb's extra effort.
