Riding the KTX Train from Seoul to Busan and Vice Versa (Where to go, what to expect, how to book a ticket through KTX website, plus book your seat in advance!)

I was able to convince my friends to stay for a night at Busan since I  saw somewhere that the sunrise at Busan was too beautiful for words and photos cannot give justice to how it looks in real life.

Busan is actually far from Seoul and you need to ride the KTX train. There were not much blogs that wrote about this so I’m glad to be able to be one of those who will share the “how to” to you guys! The train ride from Seoul to Busan is around 2hr40min and from  Busan to Seoul is the same (2hr40min).

First thing to do is book a Korail ticket on the KTX website -> click me

This is what you’ll see when you click the “click me”

1. Choose your Korail Pass Type
2. Enter your necessary details
3. click No for Railplus

Since we were going to spend 2 days in Busan we chose the Korail Pass FX (2days) – this is the flexi 2day Korail pass.

These are the rates:

we chose youth! youth is only valid for those who are 13 – 25 years old


There is NO MORE “Youth” option on Korail’s site. They are only offering these kind of  tickets on their site.

Upon checking, if you are considered an adult (age 13 up) – will be cheaper if you purchase from Klook’s website : click me.

Ticket still looks the same!

After paying, there will be a PDF file that you have to print/save that looks like this.

there is a table where you can place your food or coffee but there are no charging stations so make sure your portable chargers are fully charged
had to take this “zombie” photo as soon as we arrived at Busan! For those who don’t get the reference, there is a “thriller” movie from South Korea which is titled “Train from Busan” ps. my face is not sticked to the floor!! it’s just a camera angle

Go to Busan Station (this is where you go out coming from Seoul)

outside Busan station
as soon as you the station find the tickets sign
follow the “tickets” sign

we decided to eat at Ok Sushi

    1. Hi Sarah! One saver pass/person (min 2) so when you buy via Klook, you should buy 2 passes under Savers Pass option 🙂

  1. Hi! Just wanted to clarify, when you booked your KORAIL pass for your Day 4-8 from your latest Busan trip, did you choose the 4 DAY FLEXIBLE pass? We just wanted to understand how they count the number of days when buying the tickets. 🙂 So if we plan our Busan trip on Oct 30-Nov 3, does that fall on the 4DAY pass? Thank you!

    1. Hi Joy! I chose the 2 DAY flexible pass 😊
      The 2 days flexible pass should be what you will get on your Oct 30-Nov 3 trip since you only need to choose 2 dates (date of arrival and depature at/from Busan) and the 2 dates are within the 10 day gap as per their requirements 💖

      If I wasn’t able to explain clearly please let me know!

      1. Thank you for the quick response! 🙂 Okay, from what I understand, the 2 day flexible pass means the “usage” of the pass and not the duration of your stay. Oct 30 (1st day pass) and Nov 3 ( 2nd day pass)? Is that correct?

        PS. Been following your blog for a long time now and we once were in the same train heading to Nami. 🙂

      2. Yes, correct! It’s just “usage” of the pass 😊and since your first chosen date and second chosen date is within a 10 day gap, you can avail the 2 day flexible pass 💖

        Aww! Thank you for supporting my blog! Oh really? Say hi when you see mee next time! Would love to meet you

      3. Oh okaaayyy. Got itttt. 🙂 Thank you for clarifying and for responding so patiently. Sorry, I have another question though. Were you able to reserve a seat and time for the tickets in advance? If so, is it easy? 🙂

        I was too shy to approach you. Maybe next time! 🙂

      4. Yes 🙂 I think there was an instruction on Korail’s page for the reservation! If not, you can head to the station and show the ticket you bought and they will give you a seat and the closest time avaible 🙂

        Don’t be shy next time!! 😆

      5. Got ittttt. Thank you soo much, Regine. Looking forward to your future travel blogs. ♥️

  2. hi , I would like to ask it will be good tat to purchase the ticket in advance 1st or its fine to buy on the day we travelling down busan?

      1. ok , thank you .coz I see a lot ppl say it was quite hassle and no English language from the machine . Tats reason why I’m checking .

  3. we have 3 person travelling there , but from the link you given “Click Me” I don’t see the option for 3 person (Saver option) .How should I go with that ?

    1. Hello Yvonne 🙂 it depends on what ticket you will purchase . If you copy my ticket then yes it is the 2 way / round trip from Seoul to Busan and vice versa

  4. Hi Regine, nice informative blog! yours is the only one with pictures and idiot-proof instructions 😀

    I have questions:

    1. How many types of KTX to Busan are there? Is there like a version where it is first-class (more spacious, more legroom, etc)? Also, where did you store your suitcases and stuffs when you take the KTX?

    2. The PDF is kinda like the invoice where I have to print it out and show them to the counter staff in exchange for the tickets? In the event that I reserved a round-trip, both tickets (to and fro) would be issued on the same day?


    1. Hello Mel! Thank you for your kind words💖

      1. The train name is KTX so there is only 1 type.
      For suitcases – during my first trip, I only brought a hand carry so it was easy to squeeze it in front of my seat since I am small but during my second trip, my parents brought a big luggage and they placed it at the back of the cart (you will notice a space as you enter)

      2. Yes the PDF is sort of like your invoice and proof that you paid for your ticket.

      For the reservation of round-trip, you will be issued tickets on the day that you will use it. So let’s say you are headed to Busan on the 1st, they will only issue you tickets as you depart for Busan on the 1st. Then, if you are leaving Busan let’s say on the 5th, then they will issue you tickets as you leave Busan on the 5th.

      Hope I was able to answer your questions! Don’t hesitate to ask me if you want to know something
