Quick answer: Seoul Light, the city’s rotating riverside laser-art festival, lands on Nodeul Island from October 2 (Friday) to October 11 (Sunday), 2026. It’s Korea’s largest riverside laser art festival, free to attend, and built around this year’s “Bitseom 3L” theme. The festival moves to a different Han River island every year, and 2026 is Nodeul’s turn — a small, walkable island reachable directly by subway, which makes it one of the easier Seoul Light editions to fit into a trip.

When and Where Is Seoul Light 2026?
This year’s Seoul Light festival runs October 2 through October 11, 2026 on Nodeul Island, the small riverside park in the middle of the Han River between Yongsan and Dongjak districts. It’s the city’s flagship laser and media-art event, produced by the Seoul Metropolitan Government, and it bills itself as the country’s largest riverside laser art festival — the whole island’s riverbanks and open lawns become a nighttime projection ground for the 10-day run, according to the festival’s official site.
What Is the “Bitseom 3L” Theme?
The 2026 program is built around a theme the organizers call “Bitseom 3L” — “Bitseom” (빛섬) translates roughly as “island of light,” and the 3L stands for three strands of programming: Laser Art (the large-scale projection and laser work that anchors each night), Light of Companionship (smaller, more intimate lighting installations meant to be experienced with the people you’re with), and Lecture (talks or artist sessions that run alongside the visual program). That structure gives the festival more to do than a single big nightly show — worth budgeting extra time on the island beyond just watching the laser display.
Why Nodeul Island This Year?
Seoul Light isn’t tied to one location — it rotates every year among six Han River islands and parks: Nanjido, Yeouido, Seorae Island, Nodeul Island, Ttukseom, and Seonyudo. 2026 is Nodeul’s turn to host. That matters if you’ve been to a past edition somewhere else on the river, because the setting changes the whole feel of the event — Nodeul is compact and car-free at its core, with none of the traffic you’d navigate around a bigger park like Yeouido.
One mix-up worth avoiding: Seoul Light Nodeul Island is a separate event from Seoul Light Gwanghwamun, the city’s winter light festival that runs December through January around Cheonggyecheon and Gwanghwamun Square. They share a name and a city sponsor, but different location, different season, and different program — don’t plan a fall trip around the winter one by mistake.
Is It Free, and How Do You Get There?
Like the rest of the Seoul Light series, the Nodeul Island edition is a free, open-air public event — no ticket or advance registration needed for the general laser art program. Getting there is unusually simple for a Han River festival: Nodeul Island has its own subway stop, Nodeul Station on Line 9, with an exit that leads directly onto the island, so there’s no bus transfer or long walk from the nearest station the way some riverside parks require. Arrive after sunset for the laser and light installations to read clearly against the dark water.
Where to Stay Near Nodeul Island
Basing yourself in Yongsan or along the Ichon riverside puts you one or two subway stops from Nodeul Island, close enough to walk back after the show ends rather than crossing the city late at night. It’s worth comparing hotel rates around Seoul🏨 for your travel dates, or checking availability near Yongsan and the Han River🏨 if you’d rather stay within easy reach of the island itself.

If you’re building a broader Seoul itinerary around this trip, our things to do in Seoul guide covers the city’s other major sights alongside the river. And if your dates overlap, the Han River Drone Light Show runs its own fall 2026 season at Ttukseom Hangang Park, on the opposite side of the river — an easy pairing if you want two after-dark river shows in the same trip.
