Traveling in Korea for Chuseok 2026: Transit, Closures, and Seoul–Busan Plan B

Chuseok’s official 2026 holiday runs September 24–26, with Chuseok Day on September 25. Here is a practical sequence for checking rail tickets, closures, and backup plans in Seoul and Busan.

Chuseok 2026 in Korea: book the checks before the itinerary

The official 2026 Chuseok holiday runs from Thursday, September 24 through Saturday, September 26, and Chuseok Day is Friday, September 25.¹⁴ Many people will also have Sunday the 27th off, but Monday, September 28 is not an automatic substitute holiday as checked on September 17, 2026. Recheck government announcements and your employer or school calendar on departure day in case a temporary holiday is declared.

The useful order is transport ticket → venue operation → weather and same-day notice. This article was checked on September 17, 2026. Special transport, closures, event schedules, sellouts, and temporary-holiday decisions are time-sensitive and must be checked again on the operator’s official channel the same day.

1. Intercity travel after the advance-sale window

Holiday trains sell out earlier than ordinary services. Use KORAIL’s official 2026 Chuseok notice and KORAIL+ to look for live inventory, including seats returned after payment deadlines.² A screenshot or search result is not a ticket: confirm the reservation, payment status, station, and train number inside the official service.

For travel from September 2026, the sales system for high-speed trains serving Suseo was integrated into KORAIL+ and the KORAIL website. Former SR-only members need to complete integrated membership to retain member benefits, although non-member purchases remain available.³

If your preferred train is gone

• Search more than one station pair: Seoul, Yongsan, or Gwangmyeong at one end; Busan or Gupo at the other.

• If the date is flexible, move the long-distance segment to before September 23 or after September 27.

• Compare conventional rail and official express/intercity-bus booking channels, not only high-speed rail.

• Avoid unofficial resale, implausibly short transfers, and screens that show a seat before payment is complete.

• On the day, recheck delays and platform changes in the operator app and station displays.

2. Check closures venue by venue

Government offices and banks close on public holidays, but palaces, museums, markets, and shops do not follow one universal rule.¹ Do not build an itinerary around the claim that “tourist attractions stay open.” Some palaces may announce holiday access while facilities such as the National Palace Museum list Chuseok Day closures. Check both the Royal Palaces and Tombs Center and the specific venue.⁶

Verify opening hours, last admission, reservation rules, shifted weekly closing days, and whether exhibitions or guided tours close separately. Restaurants and traditional-market stalls may follow family schedules; call or check an official social account rather than relying only on a map app’s “open” label.

3. Seoul Plan B: one verified indoor stop plus one outdoor stop

A resilient Seoul day pairs one palace or museum confirmed open in the morning with a low-reservation walk in the afternoon. Seoul lists a free Chuseok program at the Seoul Baekje Museum complex on September 26, 10:00–17:00.⁴ It also lists a Moonlight Chuseok Festival at Jamsugyo Bridge and Banpo Hangang Park on September 27, 15:00–18:00 and recommends public transport because of road controls and limited parking.⁵

Schedules, rain cancellation, queues, and registration rules can still change. These are temporary schedules checked September 17, 2026; recheck the Seoul event page and organizer notice on the day. If an event is canceled, switch to a ticket-free route such as the exterior of Gyeongbokgung, Cheonggyecheon, or a Hangang park.

4. Busan Plan B: hillside by day, waterfront by night

In Busan, place an outdoor landscape such as Gamcheon Culture Village in daylight and use a subway-accessible waterfront such as Gwangalli in the evening. Individual cafés, galleries, and shops at Gamcheon may close; distinguish public lanes being accessible from every business being open.

Visit Busan lists a Chuseok moonlight drone-and-laser show at Gwangalli Beach on September 26, but explicitly warns that rain, strong wind, typhoon conditions, or communications problems can cause cancellation or delay one day before or on the day.⁷ Treat the show as a bonus to a beach walk and meal, not the sole reason for a cross-city journey. Some facilities, including the Bosu Book Street Tourist Information Center, explicitly list Chuseok Day as closed.⁸

5. A 24-hour and same-morning checklist

Twenty-four hours before

• Confirm the ticket, payment, departure station, and train number in KORAIL+.

• Check each venue’s official Chuseok opening, closure, and reservation notice.

• Check Seoul or Busan event pages for time, registration, and weather cancellation.

• Save two or three restaurants in the same neighborhood instead of relying on one.

On the morning of travel

• Recheck train or bus delays and platform changes.

• Recheck same-day notices from palaces, museums, and tourist centers.

• Replace beaches and outdoor events if heavy rain or strong wind is forecast.

• Put the immediate backup stop on your map whenever opening cannot be confirmed.
