Seoul Running Routes Beyond the Han River: Namsan & More

Most talk about running in Seoul starts and ends at the Han River. I’ve covered the river’s starting points and summer timing separately in the Seoul Han River running guide, so think of this as the sequel. It’s for travelers staying far from the river, or anyone who misses hills and trees.

Seoul is ringed by mountains, so once you leave the river you get flat paths along palace walls, a road wrapped around the side of Namsan, and the ups and downs of a 600-year-old fortress wall. Below, we go through official distances, surfaces, night access and bag storage, one by one.

Where can you run in Seoul besides the Han River?

It depends on what you’re after. For flat pace runs, Seokchon Lake and Olympic Park. For hills and shade, Namsan. For a sightseeing jog, Gyeongbokgung and Cheonggyecheon. For trees, Seoul Forest.

How do you run the Gwanghwamun, Gyeongbokgung and Cheonggyecheon downtown loop?

The basic plan: start at Gwanghwamun Station, run one lap of the Gyeongbokgung stone walls, and if you have energy left, drop down into Cheonggyecheon from Cheonggye Plaza. It’s a way to skim the city’s headline sights without queuing for anything, which makes it efficient for a short trip.

Gyeongbokgung stone-wall loop: 2.5–2.6 km per lap

According to the Seoul city government, the Gyeongbokgung stone-wall path is about 2.6 km, a 40-minute to one-hour walk. The Korea Times, in an August 2026 article, put the loop at 2.5 km, or 5 km for two laps. It’s flat: from Exit 4 of Gyeongbokgung Station you pass the National Palace Museum of Korea, Yeongchumun, Sinmumun, Geonchunmun and Dongsipjagak, then come back to Gwanghwamun.

That said, the areas in front of Gwanghwamun and Sinmumun fill up with crowds taking photo-op shots (인증샷), and you’ll wait at crosswalk lights, so this is really a sightseeing jog. The wall path is a public sidewalk outside the palace, so the palace’s Tuesday closure doesn’t affect it.

Cheonggyecheon: flat with no traffic lights, but narrow

Cheonggyecheon starts at Cheonggye Plaza, right next to Gwanghwamun. According to the Seoul Facilities Corporation, the stream is 8.12 km long, of which 5.84 km from Gwanghwamun to Sindap Railway Bridge is the section restored in 2005, lit by more than 10,000 lights. It’s a waterside path, so the big plus is that you can keep running without stopping for lights.

The downside is width. The upstream downtown stretch is packed with strollers and tourists, so passing is hard. The officially banned activities are cycling and inline skating, bringing animals, smoking, drinking and the like. Running isn’t on the list, but slow down where it’s crowded. For what to see along the way, see the Cheonggyecheon walking guide.

What are Namsan and Seoul Forest like for running?

Namsan means hills and shade; Seoul Forest means flat paths and greenery. Both give you long stretches with no cars.

Namsan North Circular Road: a car-free 3.5 km mountainside road

According to the Seoul city government, the North Circular Road runs about 3.5 km from the rest area at the entrance near the Namsan Cable Car to the front of the National Theater of Korea. It’s a gently sloping, pedestrian-only road 6–8 m wide, surfaced in urethane. It’s more “hill road” than “trail,” which makes it great hill training, and the Hoehyeon Station Runner Support Space’s program has run here too. If you’re staying around Myeongdong, leave your bag at the Line 4 Hoehyeon Station Runner Support Space and head out from there. One catch: with runners flocking here, Namsan Park has been asking people since September 2026 to refrain from running in groups of five or more that block walkers, and from running shirtless (as reported by The Fact). If you’re in a bigger group, split into pairs. The full rules are in Korea’s running etiquette and local rules.

Seoul Forest: 22.7 km of pedestrian-only paths

Seoul Forest covers more than 480,000 m², and since March 26, 2026, its park paths, 22,747.6 m in total, have been designated pedestrian-only, so cyclists have to dismount and walk their bikes. According to Seoul Forest’s own guidance, the park is open free, 24 hours a day, 365 days a year, but the sports facilities can’t be used at night. There’s no official running loop, so wander freely between the Ginkgo Forest and the deer enclosure, and just watch out on the stretch from the Ttukseom Water Purification Center to the Han River, where bikes are allowed.

Right now, the Seoul International Garden Expo 2026 (May 1 to October 27) is running around Seoul Forest, so weekend afternoons get busy. A morning run followed by brunch in Seongsu-dong is a good plan. For places to eat, see local eats and cafes around Seoul Forest and Ttukseom.

Seokchon Lake or Olympic Park: what's the difference?

Seokchon Lake is a simple loop where you repeat the same 2.5 km lap; Olympic Park is a park where you pick from five courses of different lengths and difficulty.

Seokchon Lake: 2.5 km around, single file

According to the Seoul city government, Seokchon Lake is 2.5 km around and split into an East Lake and a West Lake by Songpa-daero. It’s flat, so holding a pace is easy, but there are plenty of walkers too. According to 2024 reports by Aju Business Daily and Newsis, Songpa-gu hung banners on the walkway asking people to “refrain from running in groups of three or more.” Running alone or in pairs, single file, is the polite way to do it; local rules by district are covered in Korea’s running etiquette and local rules. During the spring Lake Cherry Blossom Festival, the crowds come for the flowers, so move to Olympic Park.

Olympic Park: five official jogging courses

It’s a rare park whose operator publishes its own jogging course distances. The park says the outer “Path of Youth” is used as a venue for all sorts of running races.

🏟️ Olympic Park walking and jogging courses (Olympic Park official guide)

Course	Distance	Route	Good for
Lakeside Path (호반의 길)	1,302 m	Loop from Peace Plaza around SOMA Museum of Art	Warm-ups, recovery runs
Earthen Fortress Path (토성의 길)	2,210 m	Mongchontoseong loop (includes the “kkaldak-gogae” climb)	Hill repeats
Path of Youth (젊음의 길)	3,150 m	Bike loop road around the park’s edge	Pace runs
Path of Memories (추억의 길)	3,350 m	Two circles around the center of Mongchontoseong	Quiet easy runs
Lovers’ Path (연인의 길)	4,290 m	Full circuit of 88 Lake and Mongchontoseong	The longest course

For a post-run meal, see local eats around Bangi and Olympic Park.

Can you run the Seoul City Wall trail?

The Naksan section is fine for an easy run, but the Inwang and Baegak sections are mountain trails full of stairs and rock, so walk them. The Seoul City Wall (Hanyangdoseong) is about 18.6 km in total, and the city divides it into four sections. Walking the wall’s circuit has an old name: sunseong (순성).

🧱 Seoul City Wall trail sections (Seoul City Wall official website)

Section	Route	Distance	Walking time	Difficulty	Running
Naksan	Hyehwamun → Gwanghuimun	3.2 km	About 1 hr 30 min	★★	Doable. Gentle, but passes through residential areas
Namsan	Gwanghuimun → Donuimun site	6.7 km	About 3 hr 30 min	★★★	Partly. Has wooden-stair stretches
Inwang	Donuimun site → Changuimun	4.0 km	About 2 hr 30 min	★★★★★	Hiking recommended. Rocky, no restrooms once you’re in
Baegak	Changuimun → Hyehwamun	4.7 km	About 3 hr	★★★★★	Hiking recommended. Long staircases

The Naksan section is the one the city describes as having “gentle slopes, suitable for walking at a strolling pace.” It passes Naksan Park and heads down toward Dongdaemun, and at sunset the wall and the city lights make a great view. But it runs through residential neighborhoods like Jangsu Village and Ihwa Village, so keep it quiet in the early morning and don’t run it as a group.

The Inwang and Baegak sections are mountain trails the city picks as venues for its trail running (트레일런) programs, but they aren’t the place to push the pace in a pair of road shoes. Inwangsan is very rocky, and Baegak (Bugaksan), at 342 m, is the tallest of the four inner mountains. The Baegak section is open 24 hours on a self-guided basis, but it has recommended hours by season: winter (Nov–Feb) 09:00–17:00, spring and autumn 07:00–18:00, summer (May–Aug) 07:00–19:00. For gear, see Korea’s hiking gear culture.

Staying in Hongdae or Yeonnam? Where to run

Gyeongui Line Forest Park is your closest option. It’s a park built on top of an old rail line that’s now underground, and according to the Seoul city government it runs 6.3 km from Yeonnam-dong to Hyochang-dong. The 5.12 km of park is cut by roads and the like into six sections, so you’ll have crosswalks to deal with, and the Yeonnam-dong end is a picnic hotspot nicknamed Yeontral Park (연트럴파크), so weekday mornings are better.

Where can you do track intervals in Seoul?

There are public stadium tracks, but opening hours and rules vary by facility.

📍 Open in Naver Map

Some tracks set a running direction or a walking lane, so check the sign at the entrance first.

When is the best time of year to run in Seoul?

Spring (April–May) and autumn (September–November) are ideal; in summer and winter, timing is everything. For fall colors, see Seoul autumn foliage timing and Seoul’s ginkgo walks.

📅 Seoul running routes by season

Season	Go for	Avoid	Related reading
Spring	Olympic Park, Seoul Forest, Namsan	Seokchon Lake in cherry-blossom season, bad fine-dust days	Seoul weather guide
Summer	Shady Namsan and Seoul Forest, dawn runs	Daytime, Cheonggyecheon on rainy days	How Koreans survive heat waves
Autumn	Anywhere, the Naksan wall at night	Downtown roads on marathon race days	Seoul parks by season
Winter	Less windy downtown routes, daytime	Mountain trails after dark, wall stairs after snow	Surviving Seoul’s winter cold

In summer, go by the Korea Meteorological Administration’s alerts. A heat-wave advisory is issued when the daily maximum feels-like temperature is expected to be 33°C or higher for two or more days, and a heat-wave warning at 35°C or higher.

Where do you leave your bag and shower while traveling?

Bags go in a Runner Support Space or a station locker; showers are a hotel thing by default. Public showers are still few and far between.

🎒 Bag storage and showers for runners (based on public information, October 2026)

Facility	Location	Hours	Cost	Shower
Runner Support Space	Gwanghwamun (Line 5), Hoehyeon (Line 4), World Cup Stadium (Line 6) stations	Daily 05:30–23:00	Free entry, lockers ₩2,200 for 4 hours	None
T-Locker	332 sites at 269 stations	Varies by station	4 hours: small ₩2,200, medium ₩3,300, large ₩4,400	None
Yeouido Hangang Park shower room	1F, Yeouido Hangang Park information center	Daily 06:30–22:00	Free	5 stalls each for men and women, 20 minutes max
Namsan runners’ shower (reported)	Namsan, run by Jungbu Park & Leisure Center	To be confirmed	Free	Private stalls

T-Locker charges an extra ₩500 (small), ₩800 (medium) or ₩1,000 (large) per additional hour, and you can’t store valuables or food. I couldn’t confirm whether the shower room at Ttukseom Station’s Fit Station (a 2025 pilot) is running this year.

Is it safe to run in Seoul at night?

Downtown and the big parks still have people around at night; what you really need to watch is facility hours, weather and terrain, more than crime.

For using an ER, see the Seoul emergency room and 119 guide; for getting home late, the Seoul late-night transport guide.

When are you most likely to run into a running crew?

Generally before and after weekday commuting hours, and on weekend mornings. As of autumn 2025, the Runner Support Spaces’ free programs also ran at 7 p.m. on Tuesdays and Thursdays and 7 a.m. on Wednesdays. How to join a running crew (러닝크루) as a guest is covered in the Seoul running crews guide. If you’ve only just taken up running (Koreans call beginners reonlini, 런린이), you’ll be more comfortable running solo on a weekday morning.

On weekend mornings, the roads are a factor too. On marathon race days, roads around Gwanghwamun, Jongno and Jamsil are closed, and the city also runs “Swieom Swieom Morning” (take-it-easy morning), opening some lanes for people to walk and run (Sundays 07:00–09:00 as of July). Check marathon-season road closures and safety tips first.
