How to Go from Seoul to Busan

1. Seoul to Busan via Train: KTX, ITX-Saemaeul, or Mugunghwa-ho

Going to Busan via train is perhaps the most popular choice among travelers nowadays. Thanks to that awesome zombie flick, the train ride from Seoul to Busan has become quite an experience (I admit I daydreamed about fighting off a bunch of the zombies while on board.). But what I liked about my train to Busan experience (the KTX train, to be specific) was that it was very comfortable and took me right to the destination much faster than the other options. Below let’s look at the three types of train that can take you from the capital of Korea to Busan:

1.1 KTX Train to Busan

The KTX Train is a speed monster. A one-way trip to Busan via a regular train typically takes 4-5 hours, but the KTX can take you there in just around 2 hours and 42 minutes. This is the perfect option to take if you’ll only spend 1-2 days in the locale; the KTX could save you more than 5 hours of regular travel time, which is best spent exploring Haeundae, Jagalchi, or Gamcheon Culture Village.


The KTX train from Seoul to Busan also comes highly-recommended since it has the most number of trips per day. Whether you want to travel early morning or late at night, there is a KTX train that you can take.

  • Estimate Cost of a One-way KTX Train Ticket (Seoul to Busan)
    • Standing Ticket (Adult): ₩50,800 or $47
    • Standing Ticket (Child): ₩25,400 or $23.5
    • Economy (Adult): ₩59,800 or $55.4
    • Economy (Child): ₩29,900 or $27.8
    • First Class (Adult): ₩83,700 or $77.5
    • First Class (Child): ₩53,800 or $50
  • Estimate Price of a Return KTX Train Ticket (Seoul to Busan)
    • Standing Ticket (Adult): ₩101,600 or $94
    • Standing Ticket (Child): ₩50,800 or $47
    • Economy (Adult): ₩119,600 or $110.8
    • Economy (Child): ₩59,800 or $55.6
    • First Class (Adult): ₩167,400 or $155
    • First Class (Child): ₩107,600 or $100

If you’ll go by the KTX high-speed train, you can either purchase your single-journey tickets at the Korail website or Seoul Station. Alternatively, you may also want to purchase a Korail Pass. The Korea Rail (Korail) Pass is a transportation card that’s designed for foreign tourists who are planning to make their way to cities and provinces outside Seoul. With Korail, you can book unlimited trips to popular destinations like Daegu, Daejeon, and Busan for a set duration of time. Getting this transportation card will definitely save you more money if you’ll be traveling across the country.

Going back to KTX, know that if you’ll take this option, you will get to enjoy premium seating and amenities, such as power plugs and handy seat trays. Of course, if you’ve seen Train to Busan or the Korean drama I Am Not a Robot, you’ll definitely be familiar with the interior of these trains.

1.2 ITX-Saemaeul Train to Busan

The travel time of the ITX-Saemaeul train is approximately 5 hours and 13 minutes. Seats are comfortable and you’ll also find power plugs available for use.

If you want to save some money, have a decent ride, and do not mind a longer travel time, I’d say the ITX-Saemaeul for Seoul to Busan is the perfect option for you.

  • Estimate Cost of a One-way Ticket (Seoul to Busan train)
    • Economy (Adult): ₩42,600 or $39.4
    • Economy (Child): ₩21,300 or $19.7
    • Standing Ticket (Adult): ₩36,200 or $33.5
    • Standing Ticket (Child): ₩18,100 or $16.7

1.3 Mugunghwa-ho Train to Busan

The travel time for a Seoul to Busan trip via Mugunghwa-ho train is around 5 hours and 26 minutes, which is just a couple of minutes more than that of the ITX-Saemaeul’s. However, this is not the most comfortable train out there since it was built more for standing passengers in mind. The flooring and seats are a bit outdated, which may not be appealing for some.

However, the beauty of taking the Mugunghwa-ho is that you get to spend less! A one-way ticket from Seoul to Busan only costs around ₩28,600 or $26.5, which is less than half the cost of a one-way economy KTX ticket.

  • Estimate Cost of a One-way Ticket (Seoul to Busan train)
    • Economy (Adult): ₩28,600 or $26.5
    • Economy (Child): ₩14,300 or $13.2
    • Standing Ticket (Adult): ₩24,300 or $22.6
    • Standing Ticket (Child): ₩12,100 (around ₱590 or $11.2)

Buses are also a great way to travel from Seoul to Busan. It’ll feel more private and intimate since it’s less crowded. Compared to Mugunghwa-ho seats, the express bus offers more comfort. In terms of travel time, it’s also not half-bad since express buses only take around 4 hours and 15 minutes to reach Busan.

Moreover, the express types of buses take the expressways and make 1-2 stops. Mid-trip bus stop/s are usually done at the Sunsan Service Area, where you can grab a bite of hotteok (pancake with sweet fillings)!

Bus fares for Seoul to Busan vary depending on the schedule of your trip and whether you want to take the more premium bus. Here are the options for you:
