What is the easiest way to get around South Korea as a tourist?

For intercity travel, KTX high-speed rail is the default - fast, punctual, and comfortable. Within cities, the metro systems in Seoul, Busan, Daegu, Daejeon, and Gwangju are clean, bilingual, and affordable. A single T-money card works across all metro systems and city buses. For rural areas and smaller towns not served by rail, express buses from Seoul's Gangnam or Dong-Seoul terminals fill the gaps. A rental car is worthwhile only on Jeju Island or for very rural itineraries.

Is the Korea Rail Pass (KR Pass) worth buying?

The KR Pass (KORAIL Pass for foreigners) pays off if you plan three or more long-distance KTX journeys. A 3-day flexible pass costs approximately USD 105 as of 2026. Two Seoul–Busan return journeys would cost around USD 88–100 at standard rates, so the pass becomes worthwhile from the third journey onwards. It must be purchased outside Korea - buy in advance directly from the Korail website.

Do I need a separate card for every city's metro system?

No. A single T-money card works on metro systems in Seoul, Busan, Daegu, Daejeon, Gwangju, and Incheon, as well as intercity buses and city taxis in most regions. Buy one at any convenience store (GS25, CU, 7-Eleven) for approximately KRW 4,000 and top up at station machines or convenience stores throughout the country.

Getting Around South Korea | The South Korea Guide

South Korea has one of the best public transport networks in Asia. For most itineraries - Seoul to Busan, Busan to Gyeongju, across Jeju, or anywhere along the coasts - you can travel comfortably without a car. This guide covers every mode of transport you’ll use as a visitor, how to book them, and what they cost.

KTX High-Speed Rail: The Backbone of Intercity Travel

The KTX (Korea Train eXpress) is the fastest, most convenient way to move between major cities. Seoul to Busan takes approximately 2 hours 15 minutes; Seoul to Daegu 1 hour 40 minutes; Seoul to Gwangju Songjeong 1 hour 40 minutes; Seoul to Gyeongju 2 hours.

Booking KTX tickets: Foreign visitors frequently have credit card issues on the official Korail website (letskorail.com). The most reliable alternatives are:

Korail station counters - staff at Seoul Station, Busan Station, and major hubs have reasonable English ability; you can pay by card or cash
Trazy (trazy.com) - accepts international cards, English interface, reliable seat allocation

KR Pass (Korea Rail Pass): This foreigner-only pass gives unlimited KTX travel on selected days within a validity window. Options include a 2-day flexible pass (approximately USD 75) and a 3-day flexible pass (approximately USD 105) as of 2026. Buy in advance via the Korail website before departure - the pass cannot currently be purchased inside Korea. It breaks even from the third long-distance journey onwards.

SRT (Super Rapid Train): A competing high-speed service departing from Suseo Station in southern Seoul (metro line 3). SRT fares are 10–15% lower than equivalent KTX fares - Seoul to Busan at approximately KRW 52,600 standard class as of 2026. The KORAIL Pass does not cover SRT; you must buy separate SRT tickets.

Express Bus: Budget Option Between Cities

Express buses (고속버스) connect virtually every city and town in Korea, including places not on the rail network (Jeonju being the most notable example). Seoul has two main bus terminals:

Seoul Express Bus Terminal (고속터미널): On metro lines 3, 7, and 9. Serves destinations to the south and southeast including Busan (approximately 4h 30m), Gyeongju (approximately 3h 45m), and Gwangju (approximately 3h 30m).
Dong-Seoul Terminal (동서울터미널): On metro line 2 (Gangbyeon station). Serves eastern destinations including Sokcho (approximately 2h 30m) and the Gangwon-do region.

Fares are significantly lower than rail - Seoul to Busan by standard bus runs approximately KRW 23,900; by premium (우등) bus approximately KRW 35,200 as of 2026. Book via the KOBUS app or Bustago website, both of which accept international cards.

Premium buses (우등) are worth the extra KRW 10,000–15,000 for journeys over 2 hours - they have 3-abreast seating instead of 4-abreast, more legroom, and air conditioning that actually works.

Seoul Metro: The Gold Standard for Urban Transport

Seoul’s metro system has 9 main lines plus several extensions, covering the city comprehensively and connecting to Incheon (line 1 and the AREX airport express) and Suwon. Operating hours are approximately 05:30–00:00. Trains run every 2–5 minutes on major lines during peak hours.

Fares: Base fare KRW 1,400 as of 2026 using a T-money card (KRW 1,500 for a single-journey paper ticket, which includes a KRW 500 refundable deposit).

Navigation: Google Maps works well for Seoul metro routes and shows real-time arrival times. The Kakao Maps app (the Korean equivalent) is marginally more accurate for buses. Every metro station has bilingual Korean/English signage and recorded announcements.

Key lines to know:

Line 2 (green circle line): Loops around the main Seoul urban area - Hongdae, Sinchon, Ewha, Gangnam, Jamsil, and back
Line 9 (gold): Express service from Gimpo Airport to Gangnam, much faster than other options for the western airport transfer
Airport Express (AREX): Incheon Airport to Seoul Station in 43 minutes (all-stop service) or 51 minutes (express). The ‘direct train’ takes 43 minutes and costs KRW 11,000 one-way; stopping service takes 51 minutes and costs KRW 4,800 with T-money.

T-money Card: The One Card You Need

The T-money card is a rechargeable transit card that works on every metro system in Korea (Seoul, Busan, Daegu, Gwangju, Daejeon, Incheon), city buses nationwide, and some taxis. It is the single most useful transport item you can carry.

Buy: At any GS25, CU, 7-Eleven, or emart24 convenience store, or from ticket machines inside any metro station. Cost: approximately KRW 4,000 for the card itself.

Top up (충전): At station ticket machines, convenience stores, or T-money kiosks. Minimum top-up is KRW 1,000; recommended starting load is KRW 30,000–50,000 for a week-long trip.

Transfer discounts: Using T-money gives you free or heavily discounted transfers between metro and bus within 30 minutes, which makes buses much more useful for gap routes.

Refund on departure: Remaining balance (minus a KRW 500 administrative fee) is refundable at T-money service desks inside Seoul Station and major hubs. Keep receipts if you want a clean refund.

Intercity Buses: Getting to Smaller Towns

Beyond the express bus network, regional intercity buses (시외버스) fill in smaller cities and rural destinations. These depart from different terminals to the express buses - look for the city’s 시외버스터미널 (intercity terminal) rather than the 고속버스터미널 (express terminal).

For Jeonju, there is no KTX station - the most convenient option is an intercity bus from Seoul Express Bus Terminal (approximately 2h 30m, KRW 15,400). For Andong, buses from Dong-Seoul Terminal run approximately 2 hours 30 minutes at around KRW 17,500 as of 2026.

For bus tickets in rural areas, the Bustago website and KOBUS app cover most intercity routes and accept international payment.

Ferries: Jeju Island and the Coast

Jeju Island: Ferries to Jeju depart from Mokpo, Wando, Busan, and occasionally other ports. Journey times vary - Mokpo to Jeju takes approximately 4–5 hours; Wando to Jeju approximately 2–3 hours depending on vessel type. This is the budget alternative to flying; Jeju flights from Gimpo (GMP) take 55 minutes and frequently cost KRW 30,000–70,000 on domestic carriers. For most itineraries, flying to Jeju is faster and similarly priced once ferry + accommodation costs are compared.

West Sea islands: Several smaller island groups off Korea’s west coast (including Baegnyeondo and the Shinan archipelago) are accessible only by ferry from Mokpo or nearby ports.

Book ferry tickets directly at port terminals or through the operator’s website. Island ferries often require ID (passport for foreign visitors).

Taxis and Ride Apps

Standard Korean taxis (일반 택시) start at approximately KRW 4,800 as of 2026 and are metered. Most are reasonably honest. Night tariffs (after midnight) apply a 20% surcharge.

Kakao T is the dominant ride-hailing app in Korea - works like Uber, accepts international Visa/Mastercard, and shows fare estimates before booking. Available across Seoul, Busan, and most major cities.

International taxi (국제 택시): Seoul operates a dedicated international taxi service with English-speaking drivers, priced at a premium. Book via the Incheon Airport taxi desk or the iTaxi app.

Airport transfers: Private transfers from Incheon Airport to Seoul city are available via Kiwitaxi, Welcome Pickups, or GetTransfer - all three quote fixed prices with driver sign-on arrival, useful if you are arriving late with luggage.

Domestic Flights

Korean Air, Asiana, Jeju Air, and Jin Air connect Seoul (Gimpo or Incheon) to Jeju, Busan (Gimhae), Daegu, and Gwangju. For Seoul–Busan, the train is almost always faster door-to-door. Flights make sense mainly for Seoul–Jeju where the alternative is a 4–5 hour ferry.

Compare domestic fares on Naver Flight or Google Flights; book directly with the airline for the simplest experience.

Planning Your Route

For a typical 1-2 week Korea itinerary, a combination of KTX between major cities and the Seoul metro works for most travellers. Add rental car only for Jeju or Gangwon-do countryside. The South Korea itinerary guide has full day-by-day transport breakdowns including timing and cost between each destination.
