High-speed trains in Korea, aka KTX, make travels outside of Seoul fast and convenient. It takes around 5 hours to reach Busan on a bus from Seoul, but KTX takes you there in 2.5 hours. The only downside of KTX is that ticket prices tend to be expensive. It costs around 60,000KRW for a ticket to Busan, taking up a huge part of a traveller's budget.
KR Pass allows you to take KTX rides freely within a certain time period. The pass is perfect for those who want to explore different parts of Korea.
Select Pass allows you to choose the dates of your KTX rides while Consecutive Pass allows you to ride continuously. Pick and choose the one that suits your plan. Remember that if you book in a group of two or more, each person gets a 10,000KRW discount too!
