Getting between cities
KTX, express bus or a domestic flight — what each is good for, where to book, and the luggage tricks that make multi-city trips easier.
Pick your mode
Best for: High-speed rail between Seoul and Busan and other major cities. Departs Seoul Station and Yongsan — and, since 1 Sep 2026, Suseo too.
Book: Korail+ app or the English site korail.com/global/eng. Book early for weekends and holidays.
Best for: Since 1 Sep 2026 the trains from Suseo (Gangnam side) run and are sold as KTX, at the old SRT fare level.
Book: Korail+ app or korail.com — the separate SRT app and site no longer sell these trains.
Best for: Reaches towns the train skips. Express buses offer premium, udeung (wider) and standard seats.
Book: Kobus (express), T-money Bus (intercity) and Bustago all have English pages — or buy at the terminal.
Best for: Jeju is an island — flying is the usual way there.
Book: On the airline's own website or an online travel agency.
Korail Pass
Rail pass for foreign visitors: 2, 3, 4 or 5 days on all Korail trains including KTX (adult ₩131,000–275,000, Korail notice of Dec 2025). Buy on korail.com or at major stations. check price
Luggage delivery
Hotel-to-hotel or airport luggage services let you travel hands-free between cities. Ask your hotel concierge.
Coin lockers
Major stations have lockers.
Choose the departure station before you choose the train. Since 1 September 2026 the old SRT services run as KTX, so every high-speed train is booked in one place — korail.com or the Korail+ app — but they still leave from different sides of Seoul: Seoul Station and Yongsan, or Suseo on the Gangnam side. If you are staying south of the river, Suseo can put you much closer to your bed.
The Korail Pass is sold only to foreign visitors and covers every Korail train including KTX, in 2-, 3-, 4- and 5-day versions from ₩131,000 for an adult; buy it on korail.com or at a major station. Express buses are the other option between cities, booked on the Kobus site or at the terminal. Book early for weekends and holidays, when seats on popular routes go first.
