Dates and venues
The Seoul Metropolitan Government has announced the 2026 Seoul Winter Festival as a roughly 59-day program running from December 4, 2026 to January 31, 2027, spread across several venues rather than one single site: Gwanghwamun Square, Cheonggyecheon Stream, Seoul Plaza, Bosingak Belfry, the Dongdaemun Design Plaza (DDP), and the Han River parks. Seoul has run a version of this multi-venue winter program every year recently, so the overall shape (light displays, a market, and a New Year's countdown) is a safe bet even before every individual sub-event's exact days are locked in.
What's part of the festival
Based on how the city structured last year's edition and its published 2026 event calendar, the winter festival is really several separate programs running on overlapping schedules:
- Seoul Light Gwanghwamun — a nightly media-art light show projected across Gwanghwamun Square, free to view from the square.
- Seoul Light DDP (Winter) — a separate light and projection program at the Dongdaemun Design Plaza, distinct from the DDP's autumn edition that already ran in September 2026.
- Gwanghwamun Market — a seasonal market and food-stall area set up on the square for the run of the festival.
- Hangang River Festival: Winter, confirmed for December 19–27, 2026 at the Han River parks (Ttukseom and Banpo), including a Christmas-market-style setup, light displays, and hands-on winter activities.
- Seoul Lantern Festival — typically staged along Cheonggyecheon Stream in the same window.
- A New Year's Eve countdown on December 31, historically split across Bosingak Belfry, the DDP and Gwanghwamun Square.
Getting there by venue
Gwanghwamun Square: Gwanghwamun Station (Line 5), Exit 2, or Gyeongbokgung Station (Line 3), Exit 5, both a short walk from the square.
DDP: Dongdaemun History & Culture Park Station (Lines 2, 4 and 5), directly connected to the DDP building via underground exits.
Han River winter market (Ttukseom/Banpo): Ttukseom Hangang Park Station (Line 7) for the Ttukseom side; Express Bus Terminal Station (Lines 3, 7, 9) or a short taxi/bus ride for Banpo Hangang Park.
Cheonggyecheon Stream (Lantern Festival): Any station along Euljiro or Jonggak (Line 1/2/3), then walk down to the stream level.
Free vs. reservation-only
Walking through the light displays at Gwanghwamun Square, along Cheonggyecheon Stream, and around the Han River winter market is free in every recent edition of this festival. Certain add-on experiences — a specific stage performance, a ticketed pop-up zone, or a paid workshop inside the winter market — can require a reservation or a separate fee, the same way individual attractions inside past editions have. Check each program's own page before assuming an experience is walk-in and free.
If it's cold, wet or crowded
Seoul in December and January is genuinely cold (often below freezing at night), so dress for outdoor standing time rather than just walking. If a specific evening is very crowded — common around the New Year's Eve countdown and on weekend nights near Gwanghwamun — the Han River venues generally have more open space than Gwanghwamun Square, and visiting Cheonggyecheon on a weekday evening is noticeably calmer than a Friday or Saturday. Indoor backup options near Gwanghwamun include the surrounding department stores and the DDP's own indoor exhibition halls.
