Why You Should Buy KORAIL PASS


The KORAIL PASS is specially designed for foreign visitors who want to avail of discount rates when using the KTX train.

The normal KTX round-trip train ticket (from Seoul to Busan and then Busan to Seoul) is 119,600 won per person.

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

Why? It’s because you will save more money compared to buying the normal KTX round-trip train ticket. Refer the table above, you’ll know the answer. 😊

Using the KORAIL PASS, you will only pay 111,000 won per person for a round-trip train ticket. With that, you save 8,600 won per person or 17,200 won for 2 persons! The more people you are travelling with, the higher the savings!

The KORAIL PASS comes in several types, including 2-Day PASS, 3-DAY PASS, 4-Day PASS, and 5-Day PASS. So, if you want to buy the KORAIL PASS, here is my suggestion so you will pick the right type and save more money.

  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.
