at every subway journey.

Is the Seoul subway difficult for tourists?
Usually, no. Once you understand how fares, transfers and station exits work, the Seoul subway is one of the easiest ways to travel around the city.
Stations have numbered exits, many signs include English, and ticket vending machines provide foreign-language options.
The hardest part for many first-time visitors isn't choosing the subway line. It's choosing the correct station exit after arriving. A wrong exit at a large station can add a surprisingly long walk.

How to ride the Seoul subway step by step
T-money or single-journey ticket?
Transportation card
For most visitors who plan to use public transportation several times, a rechargeable transportation card is more convenient than repeatedly buying individual tickets.
It also allows you to use Seoul's integrated transfer fare system when the conditions are met.
When using buses and subways together, remember to tap your transportation card when boarding and getting off. The transfer system depends on those taps being recorded.
Single-journey ticket
If you don't have a transportation card, you can buy a single-journey ticket at a subway station vending machine.
Seoul's official transportation guidance states that the vending machines include foreign-language settings.
You pay the subway fare plus a ₩500 deposit. After reaching your destination, insert the ticket into the station's deposit-refund machine to receive the ₩500 back.
If you're going to use buses as well, a transportation card is generally much more practical.
How subway transfers work
Seoul uses an integrated public transportation fare system.
According to the Seoul Metropolitan Government, up to five transfers can be included under the integrated fare system, subject to the relevant conditions.
The standard transfer window is generally within 30 minutes after getting off the previous mode of transportation.
Between 9 PM and 7 AM, the transfer window is extended to 60 minutes.
You need to tap your card when getting on and off for the transfer system to recognize your journey correctly.
Station exits matter more than you think
A station might have Exit 1, Exit 2, Exit 3, all the way through Exit 10 or more.
Two exits at the same station can put you on opposite sides of a major road or several blocks apart.
Before getting off the train, check which exit is closest to your destination.
This becomes especially important at large stations and popular areas such as Myeongdong, Hongdae, Gangnam and Seoul Station.
K Local Mode will build separate Which Exit? guides for major visitor destinations because this is one of the small details that makes traveling in Seoul much easier.
Which subway app should tourists use?
For actual route planning in Korea, many visitors use Korean navigation services such as Naver Map.
The Seoul Metropolitan Government also provides the Seoul Subway app for international visitors. Its features include route information, location-based route recommendations, station guidance and nearby tourist information.
We'll cover navigation apps separately because using the right app makes transportation in Korea significantly easier.
Subway etiquette tourists should know
You don't need to memorize a long list of rules, but a few habits will make your trip smoother.
What if you enter through the wrong gate?
Some parts of Seoul's subway network allow re-entry within a limited time after exiting through the wrong gate, but the applicable lines and sections can differ.
Rather than relying on that feature, check your platform direction and exit carefully before passing through a gate.
