Self-Guided Walks in Central Seoul
Seoul’s four inner mountains carry an 18.6km defensive wall built in 1396, and the accessible piece of it, plus two flatter routes through the old city, cover a full day of walking without a car or a subway transfer partway through.
Naksan Mountain wall section
Start at Hyehwa Station Exit 2 on Line 4 and walk into Ihwa Mural Village first, then climb along the illuminated stone battlements to Naksan Park’s summit at 125 meters, descending along the wall to Heunginjimun, also called Dongdaemun Gate. The full stretch is 2.1km and takes about an hour to ninety minutes at an easy pace, and it’s one of the city’s better sunset and night walks, looking down over the lit fortifications and central Jongno. The city’s own trail notes and route map are on english.seoul.go.kr .
Bugaksan Ridge, the harder version
This route runs from Changuimun Gate to Sukjeongmun and on to Hyehwamun, passing through pine forest directly behind the former Blue House grounds. Steep granite steps line the ridge, and a section still carries bullet marks from the 1968 Blue House raid known as the 1.21 Incident. Sturdy shoes are worth having here specifically; photography is restricted in a few designated sectors along the way, so check posted signage rather than assuming a spot is fine to shoot.
Deoksugung stonewall walkway
From City Hall Station Exit 1, 2, or 12, the 900-meter Doldam-gil runs alongside Deoksugung’s granite palace walls under century-old ginkgo trees. The route connects to Jeongdong Theater, the 1897 Jeongdong First Methodist Church, the neoclassical ruins of the former Russian Legation, where King Gojong took refuge in 1896, and Ewha Girls’ High School’s Simpson Memorial Hall. It’s flat and short enough to fold into a palace-day afternoon rather than needing its own morning.
Insadong to Bukchon and Samcheong-dong
From Anguk Station Exit 6, walk Insadong-gil past its tea houses and calligraphy shops and through the Ssamzie-gil complex, then cross Yulgok-ro into Samcheong-dong’s stone-paved lanes, where contemporary galleries and hanok cafes have replaced most of the old shopfronts. This is the walk to pair with a hanbok rental, since it passes directly by Bukchon’s photogenic lanes on the way through.
Before you set out
Naver Map or KakaoMap, not Google Maps, for turn-by-turn on any of these; Google’s walking directions are broken across South Korea by national mapping export law and will misplace entrances along narrow alleys like Samcheong-dong’s. Book a guided Bukchon and Insadong walking tour on Viator if you’d rather have the history narrated than read off a phone screen mid-walk.
For the palaces these routes pass, see the Seoul sightseeing guide , and the 3-day Seoul itinerary slots one of these four walks into a single afternoon each day.
The verdict: do Naksan at golden hour and Insadong-to-Bukchon at midday; the two flat routes, Deoksugung’s stonewall and Jeong-dong, work fine at any time and are the ones to save for a rainy or tired afternoon.
