Seoul Fireworks Festival 2026: Road and Subway Closures Guide
Planning to be anywhere near central Seoul this weekend? Two big events are landing back to back, and both come with real consequences for anyone trying to get around.
The Seoul International Fireworks Festival takes over Yeouido on Saturday night, and the YTN Seoul Tour Marathon runs through downtown early Sunday morning. Both mean real road closures and subway disruptions, reported by The Korea Times and The Korea Herald on September 4. If your trip overlaps with either day, here's what changes for you.
Saturday Night: Fireworks Over the Han River
The festival runs at Yeouido Hangang Park on Saturday, September 5. The show itself is short and specific: 8:00 to 9:10 p.m., with three teams taking turns and a five-minute gap between each. Britain's Pyrotex Fireworx opens at 8:00, the U.S.'s Ace Pyro follows at 8:20, and Hanwha Corporation closes it out for Korea from 8:40 to 9:10. The festival grounds themselves are open from 1 p.m. to 10 p.m., so the light show itself is one hour out of a nine-hour event window — know that going in, and you won't burn your whole Saturday standing around waiting for something that's only ever going to take seventy minutes.
Over a million people reportedly show up for this. Seoul is deploying somewhere between 4,700 and 5,000 personnel depending on which outlet you read, which tells you the crowd estimate isn't an exaggeration.
Here's where it gets inconvenient if you're just passing through. The road along Yeouido from the south end of Mapo Bridge to the 63 Building is under full traffic control from 3 p.m. to midnight. Wonhyo Bridge closes in both directions from 9 a.m. Saturday all the way to 3 a.m. Sunday, with police running six checkpoints for people who actually need to get into the Yeouido area. On the subway side, Yeouinaru Station on Line 5 may skip stops or shut its entrances between 7 and 10 p.m. once crowd density hits whatever threshold the operator's using that night. Yeouido Station, on Lines 5 and 9, is the nearest station reported to keep running normally.
If you weren't already planning to watch the fireworks, just avoid Yeouido entirely Saturday afternoon and evening.
There's no reason to be in that neighborhood if it's not your destination.
Actually Watching It Without the Crowd Crush
If you do want to see it, the core Yeouido crowd is not your only option, and honestly not the best one for a casual visitor.
- Ichon Hangang Park, across the river, gets a clear line of sight to the same fireworks with a fraction of the density
- Banpo Hangang Park, a bit further downstream, works the same way
- Sayuksin Park is another free option on the opposite bank
- Nodeul Island Park technically has a view too, but it reportedly requires a reservation, so don't count on walking in
There's also a paid option if money is genuinely no object: Starbucks ran a premium viewing package at its Yeouido Hangang Park branch priced up to 300,000 won, or roughly $220. It sold out in about 30 seconds when tickets went live, so treat it as already gone rather than something to chase.
Past years have seen people start lining up for the good free spots as early as noon. If you want an actual unobstructed view from Yeouido itself, arriving before 2 p.m. is the reported rule of thumb. If that sounds like too much of your Saturday, Ichon or Banpo Park is the better trade: you give up being in the middle of it, and you get back your whole afternoon.
Sunday Morning: The Marathon Cuts Through Downtown
The YTN Seoul Tour Marathon runs Sunday, September 6, with an 11K and a half marathon starting from Seoul Plaza, right by City Hall. The course runs through Sejong-daero Intersection, Jongno, Euljiro, and along Cheonggyecheon before finishing near Mugyo-ro. The event window is 5:30 a.m. to 10:30 a.m., and about 1,610 traffic control personnel are reportedly working the route.
This is the part that catches visitors off guard, because it's not a river-park event you can just choose to skip. It runs directly through some of the most hotel-dense parts of the city.
| Road | Section closed | Time |
|---|---|---|
| Sejong-daero | Sejong Intersection → Sungnyemun Intersection | 6:30–8:50 a.m. |
| Sejong-daero | Sejong Intersection → Heunginjimun Intersection | 6:30–9:15 a.m. |
| Euljiro | multiple sections | roughly 7:30–9:10 a.m. |
| Cheonggyecheon-ro | full route | 7:45–10:30 a.m., rolling as runners pass |
If your hotel sits anywhere near City Hall, Myeongdong, Euljiro, Jongno, or Insadong, expect some subway exits and street-level taxi pickups to be blocked or rerouted during that window. Walking is usually still fine since the closures are for vehicle traffic, but a taxi or bus trying to cross Sejong-daero before 9 a.m. Sunday is going to sit in it, not around it.
What This Actually Means for Your Trip
If you're checking out Sunday morning and your hotel is in that zone, either finish everything before 6:30 a.m. or just plan for extra time getting to the airport limousine bus or KTX. Subway lines themselves keep running, they're just not the fastest way out of a blocked-off street.
None of this touches you if you're not staying near either zone. Yeouido and downtown Jongno/Euljiro sit on opposite sides of the city, with the Han River between them.
One more thing worth flagging: sources differ slightly on the exact Euljiro closure window, some coverage says starting around 7:30 a.m., other reports say 7:40. Either way, treat 7:30 a.m. as your real cutoff if you need to cross that street on wheels Sunday morning.
Between the two events, the fireworks are the one actually worth going out of your way for. The marathon is just something to route around.
