With over 20 subway lines, the nearest subway station is most likely just across your accommodation! One way to find out is to use Google Maps to detect the location of your Seoul accommodation and you’ll instantly find the nearest station. Most subway entrances take the form of a covered staircases by the sidewalk, accompanied by a yellow train logo.
Alternatively, you can ask your hotel’s reception area, or even access their website, for transportation information. In a matter of seconds, you’ll have your answer! Everybody uses the subway, so it should be common knowledge for locals.

Subway ticketing options

There are two primary ways to pay for your train ticket – by cash or the T-Money Card.
“Cash” means you’ll need to purchase single-journey tickets for every train ride that you take. If you only intend to use the subway less than five times, this would be a better option. Otherwise, we highly recommend purchasing a T-Money Card for your journey.
The T-Money Card also needs to be topped up using cash, however, instead of paying for a single journey, you can top it up with enough cash for the day, or even your entire trip. A minimum of ₩3000 is required to activate the pass, and tourists can put up to ₩20,000 inside their T-Money Card.
In addition to the convenience, each ride is actually cheaper with the T-Money Card.
Check out our table below for cash-basis and T-Money card fare comparison.
* Prices written above are base fares, covering the first 10 kilometers of your journey.
* An amount of ₩100 will be added for every five kilometers past the first 10 to 50 kilometers of your journey
* Past 50 kilometers an additional ₩100 will be added per 8 kilometers

Purchase your T-Money Card on Klook

Although you can conveniently pick up T-Money Cards in convenience stores around the city, we highly recommend purchasing your pass before your trip!
Each T-Money Card purchased on Klook is preloaded with ₩5000, which allows cardholders to use the subway as soon as they get off the KTX Seoul station from the airport. This is also great if you haven’t had the chance to change your cash to Korean Won (₩) just yet!
PLUS: the T-Money Card can also be used for other transportation services, such as buses and cabs. Additionally, you can also purchase items from convenience stores, vending machines, department stores, and pay phones.

  1. Identify what station you’re currently in and the station you’re headed to.
  2. Follow the line from your station to your destination.

  4. Count the stops in between the two stations on the line you’ve followed.
  5. Identify the first train line you’ll be riding and the line’s final stop. This stop acts as the direction of your train line, so take note!
  6. Follow the signs provided in the subway towards the first line of your journey.
  7. Once you’re on the platform, you’ll notice a horizontal map featuring the lists of stops divided in two. Check for the direction or final stop (mentioned in #5) and find your station.
  8. Stand behind the numbered platform lines and wait for your train!

  9. For transfers: Although it’s a good practice to take note of your transfers before boarding, the TV monitors on trains will also announce available transfers in each station

  11. For transfers: You don’t need to tap out of the station unless your connecting train is in another station.

Subway Etiquette

As tourists, it is our responsibility to abide by the rules and common courtesies of any country we visit. As for Korea, there are a couple good practices that we tourists need to observe when using the subway. Although you might encounter some offenders, and unless you want to get dirty looks (and maybe even get cursed at in Korean), you should follow these simple practices:
  1. Always stand behind the numbered platform lines.
  2. Wait for passengers to exit before entering the train car.
  3. Do not seat on train seats designated for PWD, pregnant women, and senior citizens.
  4. Stand on the right side of the subway escalators if you are not rushing.
  5. Refrain from making noise and eating inside train cars.

Operating hours

The Seoul subway is operational from 5:30 to 24:00 (1 AM, next day). However, some train lines close before this 1 AM cut off, so pay attention to the train announcements being made in each station. This way you can avoid transportation problems. Do note that not all Subway Apps do not update these closures in real time, so don’t depend on these solely!
To avoid rush hour, do not ride the train from 4:30 PM to 8:00 PM. We suggest using this time to get some good KBBQ in your stomach!
