💡 Key Summary
✅ The Korea Forest Service forecasts ginkgo peak around Oct 30 and maple around Oct 31
✅ Seoul's official foliage-trail guide lists Namsan, Olympic Park, Seoul Forest and the Jungnang Stream embankment
✅ Wet leaves are slick and deep dry leaves hide the ground, so slow down and shorten your stride
You've told yourself, "This weekend I'm running through the fall colors," right? Then you start wondering when the leaves actually peak, which route to pick, and whether it's safe to run over them. This guide is for runners in or visiting the Seoul area who want a good autumn running route, with foliage timing, route ideas, and safety tips in one place.
The forecast and route details below were checked on October 4, 2026. Foliage shifts by several days with the weather, so check the latest news before you head out.
1. When is the best time for foliage runs? Check the peak first
The Korea Forest Service released its 2026 peak-foliage forecast on September 22. According to SBS Biz's report, color starts in the northern Gangwon mountains in early October and reaches a nationwide peak by late October. "Peak" here means the mountain foliage is about 50% turned.
Here are the forecast dates from the article. It gave no separate date for Seoul's city parks. So use the ginkgo and maple dates, since those trees line many city parks, and plan for late October to early November.
| Item | Forecast peak | Note |
|---|---|---|
| Seoraksan | Oct 20 | Earliest of the group |
| Songnisan | Oct 28 | Central mountains |
| Ginkgo | Oct 30 | Forecast by species |
| Maple family | Oct 31 | Forecast by species |
Peak isn't a single day. It lasts a few days, so catching one of two weekends is plenty!
2. Four autumn running routes in Seoul: parks and riverside paths
The city of Seoul lists more than 100 foliage trails (parks, waterside, mountain paths) on its official guide page. We picked four that look easy to turn into a run. They are presented as walking paths, so slow down and give way when it's crowded.
| Route | Feature | Good for |
|---|---|---|
| Namsan Northern Loop | Pedestrian-only road | An easy city run |
| Olympic Park Mongchon Fortress | About 4.2 km, rolling ridge | A taste of hills |
| Seoul Forest | Park with big old trees | Repeating a short loop |
| Jungnang Stream embankment | Cherry and zelkova color | A long waterside run |
According to Seoul Media Hub, the Mongchon Fortress trail is about 4.2 km. It crosses the outer and inner walls on rolling ridge paths, and you can see ginkgo trees over 500 years old. The Namsan Northern Loop is described in the city's environment news as a pedestrian-only road with no cars.
💡 Tip
On a first visit, drop the time goal and just do a "sightseeing lap." Restrooms, water points and crowded stretches are best confirmed on the park map or with the park office.
3. Safety tips for running on fallen leaves
Fallen leaves are the other star of a foliage trail. According to Advnture's fall running safety tips, wet leaves are slippery and deep dry leaves hide obstacles underneath. It also suggests avoiding tree-lined routes right after rain.
- Check the ground: Skip thick piles and run down the middle of the path or on bare surface.
- Shorter stride: On slick spots, slow down and shorten your steps to keep your balance.
- Grip: Shoes with deeper lugs feel steadier on leafy paths.
- Be seen: Days are shorter, so wear reflective or bright gear in the morning and evening.
Mornings and evenings swing in temperature too, so thin layers you can peel off work best. See our running clothes by temperature guide for ideas. On short days, the safety tips in our evening running routine guide help as well.
⚠️ Caution
After rain, or on dewy early mornings, walk or jog gently across leafy sections. If you roll an ankle or slip and fall, don't push on, and see an orthopedic or sports medicine doctor if swelling or pain that makes it hard to bear weight lasts.
4. Turn foliage routes into a weekend habit
Peak color lasts a few weeks at best. So deciding "where am I running this weekend?" ahead of time is how you make the most of the season. Alternating between your usual neighborhood loop and a foliage route is easier on your body, and a new route keeps things fun enough to keep showing up.
In the Wittiz app, set "run a new route this weekend" as a single mission. If a friend is running the same route, send each other cheers, and spend the jelly you earn on distance to dress Moongti in autumn outfits. A day you'd skip alone often turns into a run once you've made plans with a friend.
The first thing to fall is your motivation to go out. Pick one route this weekend and let's go!

Wrapping Up
Three steps are enough for an autumn run: "check the peak, pick one route, take leaf-covered paths slowly." This weekend, head to the closest of the four routes and capture the view instead of a time.
