If you’re chasing fall colors in Seoul without leaving the city, Seokchon Lake in autumn is the walk to plan a slow afternoon around. Red and gold foliage circles the water, Lotte World Tower rises 555 meters above the trees, and — from late October onward — the whole loop lights up for one of Seoul’s most atmospheric seasonal festivals. Here’s my local guide to timing your visit, walking the right route, and what to know before you go.
Where Is Seokchon Lake
Seokchon Lake (석촌호수) sits in Songpa-gu, in Seoul’s southeast, split into two connected halves — East Lake (동호) and West Lake (서호) — by Songpa-daero. The full loop around both lakes is roughly 2.5 km and takes 40 minutes to an hour at a relaxed pace (Google Maps · Naver Map).
Getting there:
- Jamsil Station (Lines 2 and 8) — the most convenient starting point, especially on weekends
- Seokchon Station (Line 8) — closer to the northern edge of West Lake
- Songpa Naru Station (Line 9) — closest to the eastern edge of East Lake and Songnidan-gil
Weekends around peak foliage get busy, so subway access is genuinely the best call.

When to Go: 2026 Peak Foliage & Festival Dates
Peak foliage at Seokchon Lake in 2026 is expected to fall between October 30 and November 5, with the broader viewing window running from late October through mid-November. Weather can shift the exact dates by 3-10 days in either direction, so check current forecasts a few days before your visit.
Even better: this stretch overlaps with Seokchon Lake’s annual Autumn-Winter Illumination Festival (호수의 가을과 겨울 그리고 루미나리에), so if you time it right you can catch peak foliage in the afternoon and light installations at night in the same visit.
Festival details:
- Dates: October 31, 2026 – February 28, 2027
- Illumination hours: Daily 17:30 – 22:00
- Cost: Free (no ticket needed)

Which Side to Walk: East Lake vs West Lake
Something most first-timers don’t know: the two halves feel completely different.
East Lake (동호) — the quieter, more natural side. This is where you’ll see the postcard shots of Lotte World Tower reflected on the water framed by fall foliage, and the walking path feels more like a park loop than a tourist attraction. You’ll also spot the lake’s resident geese and ducks wandering right along the path — a small but distinctly local moment.
West Lake (서호) — the busier, more curated side. This is where Lotte World’s Magic Island castle sits, along with more of the illumination installations during festival season.
My route: Start at the East Lake side (Songpa Naru Station is closest), walk the east loop clockwise for the tower-reflection views and quieter path, then cross over to West Lake for the castle views and festival lights on the return. This way, you save the busier and more photogenic sections for the second half of your walk.
Autumn After Dark: The Illumination Festival
Once the sun goes down (around 17:30 in early November), the whole loop transforms. The Autumn-Winter Illumination Festival wraps the walking path in fairy lights, arches, tunnels, and photo installations that stay lit until 22:00 every night. It’s genuinely one of the more atmospheric evening walks you can take in Seoul during fall, and it lasts well into February — so even if you miss peak foliage, the lights are worth the visit on their own.
The best sense of the festival’s scale comes from the opposite bank — the whole tree line lights up in warm and cool tones, mirrored on the water below.
Walking the loop, the “I ♥ Seokchon Lake” photo zone is one of the more popular stops — a lit-up sign with glowing decorations that makes a good marker to time your night walk around.
Further along, you’ll walk through a fairy-light tunnel built over the path — an easy contender for the most photogenic ten meters on the whole loop.
Larger illuminated arch gates mark different sections of the festival route, each with its own design.
What to Bring & Practical Tips
- Wear comfortable walking shoes. The 2.5 km loop is fully paved and flat, but you’ll want proper shoes to enjoy it at a slow pace.
- Bring a light jacket. October and November evenings in Seoul cool down quickly after sunset, especially by the water.
- Time your visit around golden hour. Arriving around 16:00 gives you an hour of afternoon light for foliage photos, then the festival lights switching on at 17:30 as it gets dark. Best of both.
- Weekdays are much calmer. If you can, avoid weekends — the loop gets genuinely crowded during peak foliage weekends.
- Take the subway. Parking around the lake fills up fast on peak-season weekends.
Pair It with Dinner or Lotte World
Since you’re already in Jamsil, don’t cut the day short after your walk. Songnidan-gil — one of Seoul’s most talked-about restaurant strips — sits just east of the lake, a five-minute walk from the eastern edge of East Lake. Check my local’s guide to Songnidan-gil restaurants for six spots worth your appetite, from Korean BBQ to charcoal dakgalbi to Seoul-style burgers.
Visiting in October? The foliage window also overlaps with Lotte World’s Halloween season — one of the neighborhood’s most beloved seasonal events. See my full guide to Lotte World Halloween if you’re planning to fit both into a day.
Verdict
Seokchon Lake in autumn hits a rare sweet spot in Seoul — a proper fall foliage walk that requires no hiking, no bus rides, and no early wake-up. With the tower reflected on the water by day and the festival lights along the loop by night, it’s one of the few spots in the city where you can genuinely turn “watching the leaves change” into a full afternoon-into-evening plan. Add in a Songnidan-gil dinner on the walk out and you’ve got the ideal Seoul autumn day — no leaving Jamsil required.
