What time does the Seoul subway close?

There is no one closing time. The last usable train depends on station, line, direction, destination, day and operator. Check the official route information for the exact journey.

Does the last train always reach the end of the line?

No. Late services can terminate at an intermediate station, so a train arriving later may not reach your destination. Read the displayed final station.

Do Seoul subway hours change on holidays?

They can. Seoul publishes special transport measures for some major holidays and events, and different rail operators may use different schedules.

What is the backup after the subway stops?

Depending on the route, a Seoul night bus or taxi may be available. Confirm the live route and complete cost rather than assuming a normal daytime connection still operates.

Seoul Subway First and Last Trains: Plan the Right Service (2026)

There is no single Seoul subway closing time. Check your station, line, direction and the final destination shown for that train on the same day—especially around holidays and major events.

Commercial rules and operational details are checked against the official sources linked in this guide. Read our verification methodology.

Why “the subway closes at midnight” is not a plan

Seoul’s network combines services run by multiple operators. A station may serve several lines, and late trains on one line can finish at different intermediate stations. The final train entering your station is not necessarily the final train that reaches your stop.

Google Maps or a blog can be a useful draft, but use current official route information for the last journey. Seoul recommends its Seoul Subway app for route, station and passenger information.

Read the final destination, not only the direction

“Eastbound” or “toward Line 2” is incomplete. Platform displays and apps identify a terminal or intermediate final station. If your destination lies beyond it, that train does not complete the trip.

At a transfer, verify both legs. The first line may still be running while the connecting line has already ended. Add walking time through the station rather than treating the published arrival and departure as the same moment.

Same-day verification workflow

Search the complete origin-to-destination route for the actual date.
Note every operator and transfer station.
Open the final train details and read its terminal station.
Add at least one earlier service as a safety target.
Save a night-bus or taxi fallback.

For an airport, intercity train or ticketed event, the last possible subway is too fragile. Work backward from the fixed check-in or boarding deadline and choose a service with recovery time.

Holidays and events can change service

Seoul publishes special measures for events such as Seollal and New Year’s Eve. Extensions are specific to dates, lines and operators. An extension reported for last year’s event does not apply automatically this year.

Official holiday notices also warn travelers to check services run by KORAIL and other operators separately. Treat the network map as connected infrastructure, not one timetable.

First trains require the same care

An early airport trip can fail for the same reason. The first train at a station may begin from a nearby depot or intermediate point and travel only in one direction. Verify that it reaches the transfer before the next line’s required service.

Early buses or taxis may create a more reliable first leg. Compare the whole route, including waiting outside a closed station entrance.

When the subway is no longer available

Seoul operates night buses on configured routes, and taxis remain a possible fallback. Neither is a universal replacement. A night bus may require a walk and a taxi can cost more or be harder to dispatch during rain and major events.

Store the accommodation address in Korean and keep sufficient payment balance. If several travelers share a taxi, compare the group total rather than the per-person subway fare alone.

A safe late-night rule

Aim for the second-to-last workable connection, not the last scheduled train. One missed gate, wrong platform or delayed meal should not turn into an unplanned cross-city taxi. Exact same-day information and recovery margin are more valuable than memorizing a network-wide closing time that does not exist.
