Take the KTX train from Seoul Train Station directly to Busan Train Station. The ticket price for adults is 59,800 won, while for children it is 29,900 won. The journey will take roughly 2 hours and 40 minutes.

From Seoul Station, the first KTX train departs at 5:12 AM. The last one leaves at 10:27 PM from Monday to Thursday, and at 10:48 PM from Friday to Sunday. Trains run at intervals ranging from 5 to 60 minutes.

Step 1. Take a Subway to Seoul Metro Station

Step 3. Purchase KTX Train Ticket at Seoul Train Station

Ticket Office at Seoul Train Station

Upon arrival at Seoul Train Station, proceed directly to the ticketing office to purchase the KTX train ticket.

The KTX train fare varies depending on the age. It is 59,800 won for adults (13 years old and above) and 29,900 won for children (6 to 12 years old). Please note that tickets come with randomly assigned seats.

Another option is to book the KTX train ticket online, and I’ll show you later how to do it. This option is ideal for a single rider because it assigns seats by random selection.

And if you’re traveling with at least two people, it is highly suggested to purchase the KORAIL PASS. It lets you pick your preferred seats early and easily get your tickets online.

This is especially useful when you’re going to Busan during peak season or school holidays, as KTX train tickets tend to sell out quickly.

Everything about the KORAIL PASS will be explained later. If you want to check it now, just click here and you will be directed to the section on why you should use KORAIL PASS.

Step 4. Board the KTX Train from Seoul Train Station to Busan Train Station

Once you have your KTX train ticket, refer to the big departure board in Seoul Train Station to determine which track to get on the train to Busan.

The display shown in the departure board switches between English and Korean, so nothing to worry about.

Or, you can simply ask the staff in the ticket office to help you find the right track for your train.

When you reach Busan Train Station, head to Gate 2 and walk straight. In less than 1 minute, you will see the Busan Metro Station.

From Busan Metro Station, you can take the subway or bus going to other Busan attractions such as Haedong Yonggungsa Temple, Lotte World Busan and Gamcheon Culture Village.

Then for your return journey, just take the KTX train from Busan Station to Seoul Station.

Why You Should Buy KORAIL PASS

The KORAIL PASS is specially designed for foreign visitors using the KTX train. It lets you book your preferred seat in advance, unlike the regular round-trip KTX ticket from Seoul to Busan, which costs 119,600 won but assigns seats randomly.

The KORAIL PASS costs a bit more, an extra 1,400 won per person, but it’s worth it because:
  1. You can choose and reserve your seat online beforehand.
  2. You can print your tickets at home and get on the train right away.
  3. The pass allows for flexible travel dates – you can pick any two days within a 10-day window, giving you the freedom to adjust your travel plans as needed.

If you’re travelling with 2 or more people, I highly recommended to buy KORAIL PASS (Flexible 2-Day Pass).

There are several types available: 2-Day PASS, 3-Day PASS, 4-Day PASS, and 5-Day PASS. So, if you’re considering buying the pass, here’s my suggestion to help you choose the right one.
  1. Group Type: Choose “Saver (Group of 2-5)”
  2. Pass Type: Choose “Flexible”
  3. Package Options: Choose “Regular Pass”
  4. Validity: Choose “2 Days”

My suggestion above is suitable for those who are travelling to Busan from Seoul, and vice versa.

Don’t get confused with the “2 Days” validity though. This simply means that you can choose any 2 days within the 10-day validity, starting from the date you used the pass.

You can check and book the KORAIL PASS here.
