In short
- Your T-money card works nationwide — Busan, Daegu, Daejeon, Gwangju, Incheon, and Jeju (buses). One card covers subway, city buses, and most taxis across the country.
- Every metro city runs the same tap-on/tap-off system with free transfers within 30 minutes between bus and subway.
- Fares are slightly lower than Seoul: Busan ₩1,550, Daegu/others ~₩1,400 base with T-money.
- Use Naver Map or KakaoMap everywhere — Google Maps transit data is unreliable in Korea. The Seoul Climate Card does not work outside Seoul.
Korea's transit brilliance isn't just a Seoul thing. Every major city has a clean, cheap, English-signed metro and a dense bus network — and the card and apps you already use carry over. Here's what changes when you leave the capital. For the Seoul basics, see public transport.
One card, everywhere
The single most useful fact: the T-money card you bought in Seoul works in almost every Korean city — no need to buy a new one when you travel. It covers:
- Subways in Seoul, Busan, Daegu, Daejeon, Gwangju, Incheon.
- City buses nationwide, including Jeju (which has no subway).
- Most taxis, convenience stores, and lockers.
- Recharge anywhere — any convenience store or station machine in any city.
Busan
- Metro: 4 numbered lines plus the Donghae Line and the Busan–Gimhae Light Rail. Base fare ₩1,550 with T-money.
- From Gimhae Airport: Light Rail → Sasang (Line 2) → Haeundae/Seomyeon, ~45–70 min under ₩2,500; or airport limousine ~₩7,000.
- Buses reach the coastal and hillside spots the metro misses; there are also scenic coastal ferries.
Daegu, Daejeon, Gwangju & others
- Daegu: 3 metro lines; base fare ₩1,400 with T-money; color-coded buses (red express, blue trunk, green feeder, yellow circular). Metro runs ~05:00–24:00.
- Daejeon & Gwangju: single-line metros plus extensive buses; same T-money, same 30-minute transfer discount.
- Jeju: no subway — city and intercity buses (₩1,300 with T-money) cover the island; many visitors rent a car (see driving).
- Smaller cities/rural: a few rural bus routes are cash-only or use regional cards not compatible with T-money — carry some cash off the beaten path.
Apps & navigation
- Naver Map / KakaoMap — both in English, with real-time bus tracking and accurate subway routing. Use these, not Google Maps, whose Korean transit data is limited.
- Read line colors, not just station names — faster when you're rushing.
- Check the last train (~midnight in most cities) before a late dinner, or you'll need a taxi.
- Apple Wallet T-money (2026): iPhone users can now tap through gates without a physical card; coverage is strongest in Seoul and expanding to Busan, Daegu, and major cities.
Getting between cities
Within a city, use the metro/bus above. To travel between cities, use the KTX or intercity buses — note that regional bus/train terminals (e.g. Dongdaegu, Busan Station) are usually major transit hubs connected to the local metro.
Common questions
Does my Seoul T-money work in Busan?
Yes — T-money works on Busan's subway, buses, light rail and most taxis, and you can recharge it there.
Do I need a Busan-specific card?
No. Hanaro/Cashbee exist but T-money covers everything. A local card is optional for long-term residents.
Does the Seoul Climate Card work elsewhere?
No — it's Seoul-only. K-Pass rebates, however, apply across cities.
Which map app should I use?
Naver Map or KakaoMap — Google Maps transit is unreliable in Korea.
