Halloween in Seoul (2026): Itaewon, Hongdae, Road Closures and Safety Tips

Halloween in Seoul falls on a Saturday (October 31) in 2026, so the city expects big crowds in Itaewon, Hongdae and other nightlife areas over the weekend of October 30 to November 1. Seoul has announced its biggest safety plan yet: a full car ban on Itaewon-ro on Halloween night, thousands of police and safety staff, AI cameras that count crowd density, and the option to close station exits or run trains straight through busy stations. Here’s what that means for you, where to celebrate, and how to have a good night without getting stuck in a crush.

When is Halloween in Seoul in 2026?

Halloween itself is Saturday, October 31. In Korea it’s mostly a night out for people in their twenties and thirties: costumes, bars, clubs and street photos rather than trick-or-treating. Because the 31st is a Saturday this year, Friday the 30th and Saturday the 31st will be the two big nights, and some people will go out the weekend before as well.

The Seoul city government has set October 23 to November 1 as a “Halloween special measures period”, with October 30 to November 1 as the most intensive stretch. The Seoul Metropolitan Police Agency runs its own special safety period over the same days.

What safety measures will be in place?

Itaewon is where 159 people died in a crowd crush on Halloween weekend in 2022. October 29, 2026 is the fourth anniversary, and the city’s plans are built around making sure it never happens again. According to city and police announcements on October 22 and 23:

• 14 areas are being watched, eight of them closely: the Itaewon and Hongdae tourist zones, Ikseon-dong, Myeongdong, the Seongsu-dong café street, Konkuk University’s food street, Gangnam Station and Apgujeong Rodeo Street.
• About 3,270 city, fire and private safety staff will be on duty, with around 1,620 in Itaewon alone. Police say they will send about 4,600 officers to Itaewon, Hongdae, Seongsu, Myeongdong and Ikseon-dong. (Media reports give slightly different totals.)
• 361 AI cameras measure how packed the streets are. When density reaches about five to six people per square meter, city, police and fire control rooms get an alert. Drones will also watch busy spots in Hongdae, Seongsu and Gangnam.
• One-way walking: in narrow lanes such as Itaewon’s World Food Street there will be one-way pedestrian lanes, and barriers to control lines outside popular bars and clubs.
• Station controls: if a station gets too crowded, entrances can be closed and trains can pass through without stopping. Emergency text alerts can also be sent to phones.

Police have also asked people not to carry realistic props such as toy guns or knives, or dress as police officers, because these can cause panic in a crowd.

Is it OK to go to Itaewon for Halloween?

Yes, as long as you go with a plan. Itaewon is still one of Seoul’s most international neighborhoods and many bars will be busy, but Halloween there is now a far more tightly managed night than it used to be. Expect Itaewon-ro closed to cars all day on October 31, staff directing foot traffic, and possibly one-way routes in the alleys. Closures on other nights (October 23, 24 and 30) depend on how crowded it gets.

The alley next to the Hamilton Hotel, where the 2022 crush happened, has a memorial. If you pass by, keep your voice down and don’t stop there for costume photos.

For a calmer evening in the area, book a table at one of the restaurants in our Itaewon restaurants guide for the early evening and leave before the late-night peak.

What about Hongdae and other areas?

Hongdae is the other big Halloween spot, with its clubs, bars and street performers. For Halloween, some lanes on the club street will become pedestrian-only, and police may limit cars in stages from October 30 to November 1. Expect long lines outside clubs. Our Hongdae guide covers the area’s layout and the quieter streets nearby.

Seongsu-dong, Myeongdong and Gangnam are on the city’s watch list too, but they’re more about photos, shopping and dinner than late-night parties. If you want costumes and atmosphere without the densest crowds, an early evening in Seongsu or Myeongdong is a good compromise.

How can I stay safe in a Halloween crowd?

• Go early, leave early. Crowds usually peak late in the evening. Arriving around dinner time and leaving before midnight avoids the worst.
• Keep moving and keep right. Follow the walking direction staff set, and don’t stop in narrow alleys or on slopes to take photos.
• Know two ways out. Look at the map before you go and pick a meeting point a few streets away in case your group gets separated.
• If it feels too packed, leave. If you can’t move freely or you’re being pushed, head for a wider street. Keep your arms up in front of your chest to protect your breathing.
• Charge your phone and keep a Korean SIM or eSIM active so you get emergency text alerts and can use Naver Map to find another route.
• Use another station. If trains skip Itaewon or Hongik University, use the next station along the line and walk, or take a taxi from a quieter street.
• Emergency numbers: 112 for police and 119 for fire and ambulance; 1330 is the tourist helpline with English. See our emergency numbers guide.

Where can I buy a costume in Seoul?

Costume pieces, wigs, masks and face paint are easy to find in October in big stationery and variety stores and in shops around Hongdae and Myeongdong. Keep it simple: light costumes are easier in a crowd, and you’ll be walking a lot. Skip anything with realistic weapons or police-style uniforms, as police have specifically asked people to avoid them this year.

Where can I celebrate Halloween away from the crowds?

Seoul’s two big theme parks both run long Halloween seasons, and the shows come with a regular ticket, so they’re a good choice for families or anyone who’d rather avoid packed streets.

• Lotte World (Jamsil, Line 2 or 8 to Jamsil Station): its autumn Halloween festival runs until November 15, 2026, with a nightly parade at about 8:20 p.m. in the indoor Adventure area. Some sources say the festival started on September 12 and others on September 19; either way, it’s on now.
• Everland (Yongin, about an hour from Seoul): the “Blood City Zero” horror zone runs until November 22, 2026, roughly from 4 p.m. to 9 p.m. daily, with no extra charge for park visitors.

Prefer the outdoors? The 2026 Seoul Hiking Week (October 26 to November 15) lists a costume hike around Namsan on October 31. Times and sign-up details are posted on the Seoul hiking tourism Instagram account (@seoulhikingtourism_official), so check there before you go.

Is Halloween in Seoul OK with a stroller or wheelchair?

We wouldn’t take a stroller or wheelchair into Itaewon or Hongdae on Friday or Saturday night: the alleys are narrow and steep in places, and one-way walking routes can make detours long. Daytime visits are much easier. The theme parks are the better choice: Lotte World Adventure is mostly indoors with lifts, and Everland has paved paths, though it’s hilly.
