Quick answer: The Hanwha Seoul International Fireworks Festival returns to Yeouido Hangang Park on Saturday, September 5, 2026 — about three weeks earlier than last year’s edition, moved up so it lands before Chuseok and closer to Seoul’s busiest stretch of foreign-visitor season. Festival-area activities start around 1:00pm, and the main fireworks show begins at 9:10pm. Admission is free, and pyrotechnic teams from Korea, the United States, and the United Kingdom are taking part this year.

When Is the Seoul Fireworks Festival in 2026?
The 2026 Seoul International Fireworks Festival (officially “Hanwha with the Seoul International Fireworks Festival”) is set for Saturday, September 5. That’s roughly three weeks earlier than 2025’s festival, which was held in late September — organizers moved the date up to keep clear of this year’s Chuseok holiday (September 24–26) and to better reach the wave of foreign visitors who tend to be in Seoul earlier in the fall. Some listings also mention smaller lead-up activities on Friday, September 4, but the main event — and the one worth building a trip around — is Saturday night.
What Time Does the Show Start?
Festival-area activities on the ground begin in the early afternoon, from around 1:00pm, with the riverbank filling up well before dark. The fireworks themselves don’t launch until 9:10pm (21:10), with each participating country’s team taking a turn over the course of roughly an hour. If your plan is just to catch the show itself, you don’t need to be on-site all day — but you do need a spot staked out by early evening.
Where Should You Watch From?
Three spots along the river cover most of what you’ll see written about this festival:
- Yeouido Hangang Park — the launch site itself, and the most atmospheric place to watch, but also the most crowded by far.
- Ichon Hangang Park — directly across the river, with a wide, unobstructed view of the entire display without fighting the density of the Yeouido side.
- Mapo Bridge — a pedestrian vantage point that combines the fireworks with the wider Han River skyline, useful if you’d rather stand than stake out ground.
If you want a seat on the grass at Yeouido or Ichon, plan to arrive between 11:00am and 2:00pm — riverside spots with a clear sightline routinely fill up hours before the first launch, especially since this year’s earlier date still falls in warm, comfortable weather that encourages all-day picnicking.
Who’s Setting Off the Fireworks?
Hanwha, the Korean conglomerate that has run the festival since its start, leads the show as always. This year it’s joined by pyrotechnic teams representing the United States and the United Kingdom — three countries in total — each contributing its own segment with a distinct visual style, one of the draws for repeat attendees who compare each country’s display from year to year.
Is It Free, and How Crowded Does It Get?
Yes — general riverside viewing is free, with no ticket required. It’s also one of the single most crowded nights in Seoul’s event calendar, drawing well over a million people to the riverbanks in past editions. For 2026, organizers have deployed a record roughly 4,700 crowd-management and safety staff, including 1,200 Hanwha employee volunteers, and are using a real-time crowd-density tracking system built with telecom carrier data (nicknamed “Orange Safety”) alongside expanded CCTV coverage along Wonhyo Bridge and the Mapo and Ichon riverbanks to help move people safely, according to local reporting on this year’s safety plan. Confirm final show details closer to the date on the official Hanwha Seoul International Fireworks Festival site, since Korean event organizers do occasionally adjust timing for weather.
Where to Stay for the Show
Basing yourself in Yeouido itself, or in neighboring Yongsan across the river, means you can walk to a viewing spot and back without joining the crush for taxis or the subway right after the finale. You can compare rooms around Seoul for early September🏨 — book well before the date, since hotels near the river fill up fast for festival weekend — or check availability across Seoul🏨 more broadly if you’re building the show into a longer trip. For a full breakdown of neighborhoods and picks, see our guide to where to stay in Seoul.
If you’re planning a Han River-centered trip more broadly, our guide to the Han River in Seoul covers the riverside parks, picnicking, and the Banpo Bridge fountain show worth pairing with a fireworks-festival visit. Earlier this summer, the Hangang River Festival filled the same parks with water sports and concerts, and Seoul’s Han River Drone Light Show returns for its own fall run in September and October — worth checking if your dates overlap with more than one river-side event this season. If flights are still open, it’s worth comparing fares into Seoul✈️ now, since early September flights tend to fill up as the date gets closer.
