Hiking Near Seoul
Six mountains reachable by subway from COEX (삼성역). Most trails are well-marked with Korean/English signs. Bring water, a light snack, and good footwear.
관악산
Gwanaksan · 632 mThe closest major mountain to COEX reachable by direct subway — no transfers. Multiple trailheads and well-maintained paths make this ideal for a first Korean hiking experience. The summit observatory (연주대) rewards with sweeping views of southern Seoul.
Recommended Routes
Exit 3, walk ~15 min to the main trailhead. Wide, paved lower path transitions to rocky trail near the top. Passing through Gwanak Art Center area.
Exit 5, follow the signs. ~2 hrs to summit. Popular with early morning regulars. Cafes at the base open from 6am.
Tips
응봉산
Eungbongsan · 94 mSeoul's most accessible sunrise viewpoint. The short ascent is easy enough even in business casual shoes, and the octagonal pavilion (팔각정) at the top is a favourite for Han River panoramas. The entire mountain takes under an hour out-and-back — perfect before an early conference session.
The Route
Exit 1, turn left. The trailhead is immediately visible with stone steps leading uphill.
~20–30 min gentle climb. Octagonal pavilion at top — Han River visible in both directions, Achasan ridge to the east.
Tips
아차산
Achasan · 287 mA ridgeline trail hugging the Han River with ancient Goguryeo fortress ruins (5th–7th century) along the way. Well-paved paths near the base make the lower section accessible to all fitness levels. Sunset from the ridge over the Han River valley is one of Seoul's best views.
The Route
Exit 2, walk straight ~10 min to the main entrance (아차산 입구). Trail map boards at the gate.
Follow the main trail uphill past restored fortress sections. The ridge runs north toward Yongmasan — easy extension if time allows.
Han River visible to the south, Namsan Tower to the west. Return the same way or loop via the valley trail.
Tips
인왕산
Inwangsan · 338 mFamous for massive granite boulders, shamanic shrines (Inwang Seonang), and the Hanyangdoseong fortress wall that drapes across its ridgeline. Best experienced in the evening when the illuminated fortress wall creates a dramatic nightscape over central Seoul.
The Route
Walk ~20 min along Changuimun-ro toward the Changuimun Gate (창의문). Follow signs for 인왕산.
Follow the restored 14th-century city wall uphill. Stone steps are steeper here than other mountains. The wall provides a natural handrail.
360° views: Bugaksan to the north, Namsan to the south, Gyeongbokgung Palace below.
Tips
북악산
Bugaksan · 342 mThe mountain directly behind Gyeongbokgung Palace, historically restricted as it overlooks the presidential residence (Cheongwadae). Now open to the public, it offers forested trails along ancient city walls — and a rare sense of total calm compared to Seoul's busier mountains.
The Route
From Gyeongbokgung Station (Line 3) Exit 3, take bus 1020, 7022, or 7212 to Changuimun Gate (~10 min). Pick up your free access lanyard at the entrance.
Well-maintained forested trail with boardwalk sections. The fortress wall runs alongside most of the route.
Descend east toward Samcheong Park. Bullets holes from the 1968 presidential palace raid are still visible on some trees — a sobering historical marker.
Tips
북한산
Bukhansan · 836 mA full national park on Seoul's doorstep, with dramatic granite peaks, ancient Buddhist temples, and one of the world's highest visitor densities per km² among national parks. The Baegundae peak scramble is bucket-list material — but even easy valley walks are deeply rewarding.
Route Options
From Gupabal Station (Line 3), bus to Bukhansan National Park visitor center. ~3 hrs to summit including chain-assisted rock sections near the top. Breathtaking views.
Gentle stream-side walk to Seunggasa Temple. Under 2 hrs round-trip. No technical sections — great for a relaxed morning. Cool shaded trail even in summer.
The Ui-Sinseol light rail line runs to the north of the park (Dobongsan area). Slightly different character — dramatic ridgeline with granite spires.
