Korea’s long-distance bus network reaches towns the KTX never will, and for a city pair the KTX does serve, it is usually the cheaper option by a wide margin. The part that trips up first-time bookers isn’t the ride — it’s the seat class, and the fact that the official booking sites don’t always take a foreign card.

Getting around: our guide to data and map apps in Korea covers what public wifi misses and what Kakao Map or Naver Map can tell you that Google Maps still can't.

Express bus or intercity bus?

고속버스 (express bus) runs point-to-point between major cities on expressways, mostly out of large terminals like Seoul’s Central City and Gangnam. 시외버스 (intercity bus) covers everywhere else — smaller towns, more stops along the way, and a wider spread of terminals, including Seoul’s Nambu and Dong-Seoul terminals. The line between them has blurred; some of the newest premium buses technically operate under an intercity license despite running the same nonstop express routes. In practice, book by route and departure time rather than worrying about which category a given bus falls under.

What a seat class actually buys you

Seoul to Busan is the clearest example, since every class runs it:

Standard (일반)

₩26,700 · 2+2 seating, 40–45 seats per bus

Deluxe (우등)

₩39,700 · wider 3-across seating, roughly 40–50% more than standard

Premium (프리미엄)

₩51,600 · 2+1 seating, full-flat recline, personal screen, privacy curtain, USB/wireless charging

Deluxe is the useful middle ground for most trips — noticeably more legroom than standard for a fare that still undercuts the KTX on most routes. Premium earns its price on genuinely long hauls (Seoul–Busan, Seoul–Mokpo) where a flat recline matters more than the extra cost.

Booking as a foreigner

The official sites are kobus.co.kr for express buses and bustago.or.kr or txbus.t-money.co.kr for intercity buses — Bustago and TxBus both offer English, Japanese and Chinese interfaces. The catch is payment: foreign cards frequently fail at the identity-verification or payment step on the Korean-language booking flow, even when the site itself displays in English.

Three ways around it, in order of reliability:

1. International platforms — Klook or Hanpass both resell Korean bus tickets in English and take foreign cards without issue.
2. Terminal kiosks — foreign cards go through more reliably at a self-service machine than online, and most routes still have seats to sell as late as an hour before departure.
3. The ticket counter — every terminal has one, staffed, and it takes foreign cards when the kiosk won’t.

Booking ahead matters most around Korean holidays — Chuseok and Lunar New Year sell out express and intercity routes days in advance, including the deluxe and premium seats that normally have room.

Etiquette

Seat numbers are assigned and enforced — sitting in someone else’s seat because yours seems worse is not really done. Bags go in the underfloor luggage hold for anything larger than a backpack; the driver handles loading and it’s normal to point out which case is yours. Once moving, the same rules as a long train ride apply: phone on silent, no calls, no food with a strong smell. Deluxe and premium buses in particular run quiet — reclining seats and dimmed cabin lights are the default, not something to ask for.

Getting there

A Korean eSIM makes Klook and Hanpass usable for booking in the first place, and Naver or Kakao Map will get you to the right terminal — Seoul alone has several, and they are not interchangeable for every route. If the route runs on rails too, our rail pass guide works through whether the KTX actually beats the bus on your specific trip. Getting to the terminal itself is usually a subway or city bus ride, with a taxi or a Ttareungyi bike covering the last stretch if you’re cutting it close.
