How to Travel Around Korea by Train and Bus

Korea is small but well-connected. Seoul to Busan in 2 hours 30 minutes. Seoul to Jeonju in under 2 hours. Seoul to Gangneung in 1 hour 30 minutes. Once you understand the transport system, the whole country opens up for day trips and weekend travel. Here's how to navigate it.

The Quick Answer

Intercity travel in Korea uses five main systems: KTX (high-speed rail from Seoul Station), SRT (high-speed rail from Suseo in Gangnam), slower Korail trains (Saemaul and Mugunghwa), express buses from Gangnam terminals, and intercity buses from several other Seoul terminals. All can be booked in advance with foreign cards, and most have English-language apps or websites.

Understanding Korean Train Types

Before booking, it helps to understand the difference between train types. Korea has both high-speed rail and conventional rail, and they serve different routes at very different prices.

High-Speed Rail (고속철도)

"Korea's KTX high-speed train — Seoul to Busan in just 2 hours 30 minutes at 300 km/h. The fastest way to explore the country."

KTX — operated by Korail, departing from Seoul Station or Yongsan Station. Maximum speed 300 km/h. Covers the widest network including Busan, Gwangju, Yeosu, Mokpo, Gangneung, and more. The KORAIL PASS works on KTX.

"Ready to board? Show your mobile ticket QR code at the gate—no printing needed. Luggage storage at end of carriages."

SRT — operated by SR, departing from Suseo Station in Gangnam. Same speed as KTX, slightly different route coverage. Best if you're staying in the Gangnam, Jamsil, or COEX area. The KORAIL PASS does not work on SRT.

Conventional Rail (일반열차)

"Korean intercity transport at a glance: KTX (fastest), SRT (from Gangnam), Express Bus (cheapest), ITX (mid-range). Compare time, price, and routes instantly."

These trains are slower and cheaper than KTX, and serve routes and stations that high-speed rail doesn't reach.

ITX (Intercity Train Express) — several types:

ITX-Cheongchun (ITX-청춘): Yongsan → Chuncheon. Popular for day trips to Nami Island and the Gangwon region.
ITX-Saemaul (ITX-새마을): Upgraded version of the old Saemaul-ho. Covers some routes where KTX doesn't run.
ITX-Maeum (ITX-마음): Newer generation, gradually replacing older trains on certain routes.

Saemaul-ho (새마을호) — the classic long-distance express train. Slower than KTX but significantly cheaper. Makes fewer stops than Mugunghwa. Still runs on routes that KTX hasn't fully replaced.

Mugunghwa-ho (무궁화호) — Korea's original intercity train, the slowest and cheapest option. Stops at almost every station along the route. Good for reaching smaller towns not served by KTX, or for budget travelers with time to spare.

Train Type Comparison

Train	Type	Speed	Seoul↔Busan	Best For
KTX	High-speed	300 km/h	₩59,800~ / ~2h 30m	Fast travel, most destinations
SRT	High-speed	300 km/h	₩52,600~ / ~2h 30m	Gangnam residents
ITX-Saemaul	Semi-express	150 km/h	₩42,600~ / ~4h	Budget, no rush
Mugunghwa-ho	Conventional	120 km/h	₩28,600~ / ~5h 30m	Cheapest option

⚠️ Note on transfers: Some destinations require transferring from a high-speed train to a conventional train mid-route. For example, reaching Gyeongju from Seoul often involves riding KTX to Singyeongju Station and transferring to a local train. Yeosu and some Jeolla Province destinations may require a transfer at Iksan. The booking app will show transfers automatically — just check your itinerary before boarding.

💡 All fares listed are approximate base fares. Prices vary by seat class, direction, and availability. Check the Korail Talk app or korail.com for current pricing.

Express Buses — The Budget Option

Express buses are 20–40% cheaper than KTX on most routes. They take longer, but the seats are comfortable and routes cover areas trains don't always reach.

Seoul's Express Bus Terminals — Three Separate Buildings

This is where most foreign visitors get confused: there are three separate bus terminals in the same Gangnam complex, each serving different directions. They are in the same building or adjacent buildings, but you need to go to the right one.

How to get there: Subway Lines 3, 7, and 9 → Express Bus Terminal Station (고속터미널역)

Terminal	Korean	Serves
Gyeongbu Terminal	경부선 터미널	Busan, Daegu, Daejeon, Ulsan, Gyeongju
Honam Terminal	호남선 터미널	Gwangju, Jeonju, Mokpo, Yeosu
Jungang / Central City Terminal	중부선 / 센트럴시티	Gangneung, Sokcho, Chuncheon, Jeju (ferry)

⚠️ If you walk into the wrong terminal, you won't find your bus. Check which terminal your destination uses before you arrive. The apps will usually tell you, but if in doubt, ask at the information desk near the entrance.

Express Bus vs. Intercity Bus — What's the Difference?

Express buses (고속버스) use highways and make few or no stops. Faster, more comfortable, depart from the Gangnam terminals above.

Intercity buses (시외버스) stop at multiple towns along the route. Slower, but reach smaller destinations that express buses don't serve.

Seoul has several intercity bus terminals in addition to the Gangnam complex:

Terminal	Korean	Location	Serves
Dong Seoul Terminal	동서울터미널	Gangbyeon Station, Line 2	Gangwon Province, Eastern Gyeonggi
Seoul Nambu Terminal	서울남부터미널	Nambu Bus Terminal Station, Line 3	Southern Gyeongnam, parts of Jeonnam
Sangbong Terminal	상봉터미널	Sangbong Station, Lines 5·7	Parts of Gangwon Province

⚠️ Your destination may be served by an intercity bus from one of these terminals rather than the Gangnam express terminal. If you search for a destination and the Gangnam terminal doesn't show results, check the other terminals. The T-money GO app covers most intercity routes.

Seat Grades on Express Buses

Grade	Korean	Features	Price vs. Standard
Standard	일반	Regular reclining seats	Base price
Udeung	우등	Wider seats, more legroom, fewer rows	~30–40% more
Premium	프리미엄	Business-class style, large seats	~60–80% more

For routes over 3 hours, upgrading to Udeung is usually worth the cost difference.

KORAIL PASS — The Foreigner Rail Pass

The KORAIL PASS is a multi-day unlimited train pass available exclusively to foreign passport holders. It covers KTX, ITX, Saemaul-ho, and Mugunghwa-ho — all trains operated by Korail.

Who can buy it:

Foreign passport holders visiting Korea
Foreign residents with a visa valid for less than 6 months
Long-term residents (6+ months) are ineligible — a Happy Rail Pass is available as an alternative

Pass types:

Consecutive pass: valid for continuous days from first use (e.g., 3-day pass = 3 days in a row)
Flexible pass: valid for a set number of travel days within a longer window

Where to buy:

Korail official website (korail.com/global)
Korail ticket offices at major stations (exchange a voucher for physical pass)
Klook and other travel booking platforms

Important notes:

Does not work on SRT (different operator)
Does not work on Seoul subway or metro systems
Seat reservations are still required for KTX — the pass covers the fare, not the seat

🆕 KORAIL PASS PLUS (Launched December 2025)

A new integrated transit pass that combines KORAIL PASS with a rechargeable transit card for subways and buses — all in one card.

Price: From ₩131,000
Covers: KTX + ITX + Mugunghwa (all Korail trains) + nationwide subway + bus
How it works: Purchase KORAIL PASS, then add the transit card function for an additional ₩8,000. Load prepaid credit for subway and bus use.
Best for: Visitors planning to travel between multiple cities and also use public transport within each city

This is a significant upgrade for multi-city travelers — previously you needed a T-money card for subways and a separate KORAIL PASS for trains.

After You Arrive: Getting from the Station to the City

Arriving at a station is one thing — getting where you're actually going is another. Here's how it works at the main destinations.

City	Station	How to Get to the Center
Busan	Busan Station	Subway Line 1 (Seomyeon, Nampo, Haeundae)
Jeonju	Jeonju Station	Bus or taxi to Hanok Village (~15 min, ₩8,000~)
Gyeongju	Singyeongju Station	Bus or taxi to the historic center (~20 min)
Gwangju	Gwangju Songjeong Station	Subway Line 1 or taxi
Gangneung	Gangneung Station	Bus to Gyeongpo Beach or taxi
Chuncheon	Chuncheon Station	Bus or taxi to Nami Island ferry pier (~15 min)

Note: Jeonju, Gyeongju, and Chuncheon train stations are not in the city center — a bus or taxi connection is needed. Budget an extra ₩5,000–₩10,000 and 15–20 minutes for these.

Practical Tips

Book KTX at least a few days in advance on weekends. Popular routes sell out, especially Friday evenings and Sunday afternoons.

During Chuseok (추석) and Seollal (설날), book at least one month early.

⚠️ Holiday Warning: Korean national holidays are the busiest travel period in the country. Tickets release exactly one month before departure and sell out within hours. If your travel dates overlap with Chuseok or Seollal, set a reminder and book the moment tickets open.

Left luggage at major stations. Coin-operated lockers are available at Seoul Station, Busan Station, and most major KTX stations. Sizes range from small (₩2,000–₩3,000) to large (₩5,000–₩7,000) for a set period. Useful if you want to explore a city before checking into accommodation.

Missed your train? KTX tickets can be changed before departure for a small fee. After departure, a cancellation fee applies (increasing the closer to departure time). Speak to staff at the ticket window or use the app to rebook.

Seat selection tip. On KTX, seats A and D are window seats; B and C are aisle. If you're traveling solo and want a window, look for an A or D seat when booking.

FAQ

Q: Can I use a foreign credit card to book KTX? Yes. Korail Talk and the Korail website accept foreign Visa and Mastercard. Visa tends to work more reliably. If a card doesn't go through, try a different one or use Klook as an alternative booking platform.

Q: Is the KORAIL PASS worth buying? It depends on your itinerary. If you're visiting 3 or more cities by train in a week, the KORAIL PASS usually saves money compared to buying individual tickets. For 1–2 trips, individual tickets are often comparable or cheaper. Use the fare table in this guide to calculate your expected costs before deciding.

Q: Should I take KTX or SRT? If you're staying in central or northern Seoul, KTX from Seoul Station is more convenient. If you're in Gangnam, Jamsil, or near Suseo, SRT is faster to reach. Both trains have similar speeds and fares on overlapping routes. Note that KORAIL PASS works on KTX but not SRT.

Q: I need to transfer trains mid-route. How does that work? The booking app handles it automatically — you'll see both legs of your journey on one itinerary. Allow enough time at the transfer station (the app factors this in). The platform number for your connecting train will be displayed at the transfer station.

Q: Can I take large luggage on the train? Yes. There are overhead racks and end-of-carriage luggage areas on KTX. Very large bags (bigger than standard carry-on) can be stored at the ends of the carriage. There's no formal size limit, but being considerate of other passengers in a busy carriage is appreciated.

Q: Do I need to print my ticket? No. Mobile tickets work at all KTX gates. Show the QR code on your phone screen at the barrier. Keep your phone charged before boarding.

Q: Is the express bus terminal really three separate buildings? Effectively, yes. The Gyeongbu, Honam, and Central City (Jungang) terminals are in the same complex and connected, but they serve completely different destinations. If you go to the wrong one, you won't find your bus. Check which terminal serves your destination before you arrive.
