Seoul City Wall Hike 2026: 6 Sections, 18.6 km & ID Rules
Visitors who plan a Seoul City Wall hike usually discover that the wall has six sections, very different effort levels and at least one stretch that checks your ID. Picking the wrong section, or arriving without ID at the Baegak checkpoint, can cost you a half day.
This guide compares the six sections, explains the ID rule, lists the free Hanyangdoseong Museum hours and gives three plans. It draws on Seoul's official City Wall portal, Seoul Metropolitan Government media-hub pages and a May 2026 Travel News feature, with a reference date of 4 November 2026.
Seoul City Wall facts and the six sections compared
The wall follows four mountains, Baegak, Naksan, Namsan and Inwangsan, and the city portal lists the trails as open 24 hours without mentioning a ticket. It gives the wall height as 5 to 8 m, while some travel articles say about 10 m.
| Section | Length | Walking time | Difficulty |
|---|---|---|---|
| Baegak | 4.7 km | about 3 h | 5/5 |
| Naksan | 2.1 km (section) | about 1 h on the route page | 2/5 |
| Heunginjimun | 1.8 km | not checked | not checked |
| Namsan | 4.2 km (section) | about 3 h on the route page | not rated in source |
| Sungnyemun | 1.8 km | about 1 h | 1/5 |
| Inwangsan | 4.0 km | about 2 h 30 min | 5/5 |
The six section lengths add up to 18.6 km on the museum page published by Seoul. The portal's walking routes use different start and end points, so Naksan from Hyehwamun to Heunginjimun is listed at 3.2 km and Namsan from Jangchung Gymnasium to Baekbeom Square at 6.7 km; treat times as planning ranges.

Which section fits your day
Naksan, about one hour near sunset. The route starts at Hyehwamun Gate, a five-minute walk from Hansung Univ. Station (Line 4, Exit 5), and passes Jangsu Village, Naksan Park and mural-lined Ihwa Village. The portal rates it two stars out of five and asks visitors to stay quiet near residential Bukjeong Village.
Baegak, 4.7 km and about three hours. The media hub recommends starting at Hyehwamun because the Changuimun start opens with a steep climb. Listed highlights are Baekakmaru at 342 m, a pine with about fifteen bullet marks from the 21 January 1968 gunfight, the Malbawi information center, Sukjeongmun Gate and Bukjeong Village with about 500 tile-roofed houses.
Sungnyemun, easiest at 1.8 km. It runs from Baekbeom Square to the site of Donuimun Gate past Namdaemun Market, and the gate is open 09:00 to 18:00, closed Mondays, with winter hours (November to February) ending at 17:30. The portal warns that the original course is hard to follow here.
Inwangsan, 4.0 km and about 2 h 30 min. It passes Gyeonggyojang House, Guksadang Shrine and Seonbawi Rock and ends near the Yun Dong-ju Literary Museum, open 10:00 to 17:00 from November to February and closed Mondays. The portal notes many rocky sections that need extra care in winter.
Namsan, about three hours. The route passes the National Theater and N Seoul Tower, whose observatory is listed 10:00 to 23:00 (Saturday until 24:00), and the Namsan cable car runs 10:00 to 23:00 with a possible extra hour on Fridays, Saturdays and days before holidays.
The ID rule on the Baegak stretch and the free museum
Seoul's media hub states in a 2018 article that ID is required between the Malbawi information center, Sukjeongmun and Changuimun. It adds that access was restricted after 1968, reopened in 2007, and that photography is limited in places; a May 2026 Travel News feature says some sections require registration at Malbawi and close after certain hours it does not name.
Current opening hours of the information center could not be confirmed from any official page, so they must be checked before the trip. Passport is the safest ID for foreign visitors, which is a cautious reading rather than a rule stated in the article.

The Hanyangdoseong Museum is free and sits in Heunginjimun Park, about five minutes from Dongdaemun Station (Line 1, Exit 1 or 10). It opens 09:00 to 18:00 Tuesday to Sunday with last entry 17:30 and closes on Mondays and public holidays; the page dates from 2024, so confirm before a special trip.
Three plans, directions and seasonal tips
| Plan | Route | Time (estimate) | Effort |
|---|---|---|---|
| Sunset hour | Hyehwamun Gate → Naksan Park → Heunginjimun | 1 to 2 h | Easy |
| Half day | Museum → Naksan route → Heunginjimun → Dongdaemun | 3 to 4 h | Easy to moderate |
| Full day | Hyehwamun → Baegak (ID needed) → Changuimun | about 3 h walking plus stops | Hard, steep steps |
Timings in the plans are estimates built from the portal's walking times, not official itineraries. Naksan midday temperatures can reach 32 degrees Celsius in summer according to the media hub, which suggests mornings or evenings then; a 2026 Travel News feature suggests clear days for views and late autumn for foliage.
For Changuimun the 2018 article lists buses 7212, 1020 and 7022 from Gyeongbokgung Station Exit 3 plus a two-minute walk, but routes change, so check a live map. The same article gives 02-2133-2657 as the city's inquiry line, which is seven years old and should be verified.
