If you are wondering how to get from seoul to busan, you have more options than almost any other intercity route in Korea — and choosing the right one depends entirely on your priorities: speed, cost, convenience, or flexibility.
Busan is approximately 400km south of Seoul, and Korea’s excellent transport infrastructure means you can make the journey in as little as 2 hours and 20 minutes — or take your time and enjoy the scenery along the way. Here’s a complete breakdown of every option.
Whether you arrive by train or bus, you’ll need a T-money card at both ends for getting around the city. If you’re an iPhone user, don’t miss our T-money on iPhone guide before you head out.

| Express Bus | ~4–5 hrs | ₩34,000–₩50,000 | Budget travelers |

Option 1: KTX — Fastest and Most Convenient
Travel time: Approximately 2 hours 40 minutes Departure: Seoul Station or Yongsan Station Arrival: Busan Station Cost: Around ₩60,000 (standard class)
The KTX is the most popular choice for travelers heading from Seoul to Busan — and for good reason. It’s fast, comfortable, reliable, and drops you right in the center of Busan, just a short walk or subway ride from most major attractions.
Seoul Station is well-connected to virtually every part of the city via subway, making it easy to reach no matter where you’re staying. On board, seats are spacious, the ride is smooth, and there’s no traffic to worry about.
How to Book KTX Tickets
- Korail Talk app (available in English) — recommended for advance booking
- Ticket vending machines at Seoul Station — support multiple languages including English and accept international credit cards
- Station ticket counters — English-speaking staff available at major stations
- QR code kiosks at major stations — scan to access English-language booking without an app
💡 Tip: Book at least a few days in advance, especially for weekend travel or Korean national holidays. If you plan to visit other cities like Gyeongju or Jeonju along the way, the Korail Pass Plus offers much better value than buying individual tickets for each journey.
Option 2: SRT — Slightly Faster, Slightly Cheaper
Travel time: Approximately 2 hours 20 minutes Departure: Suseo Station (southern Seoul, near Gangnam) Arrival: Busan Station Cost: From around ₩50,000+
The SRT departs from Suseo Station near Gangnam — making it the natural choice if you’re staying in the Gangnam, Seocho, or Songpa districts. It’s marginally faster and slightly cheaper than KTX.
If you’re staying near central Seoul or northern areas like Hongdae or Jongno, the journey to Suseo Station may cancel out the savings. In that case, KTX from Seoul Station is more practical.
How to Book SRT Tickets
- SRT app or SRT website
- Ticket counters and vending machines at Suseo Station

Traveler’s Note: The SRT mobile app may occasionally encounter errors with international credit card payments. If you experience issues during checkout, we highly recommend using the SRT Official Website (English) via a web browser, as it is generally more stable for foreign cards.
Option 3: Express Bus — The Budget-Friendly Choice
Travel time: Approximately 4–5 hours Departure options:
- Seoul Express Bus Terminal (Gangnam)
- Dong Seoul Terminal
- Central City Terminal (Banpo)
Arrival: Busan Central Bus Terminal (near Nopo Station) Cost: Standard ₩34,000–₩40,000 / Premium (우등) ₩40,000–₩50,000
If you’re traveling on a budget or don’t mind a longer journey, the express bus is a perfectly comfortable option. Premium class buses (우등) offer wider, fully reclining seats — making the 4–5 hour ride surprisingly pleasant.
For finding bus terminals and routes, Naver Maps is essential. Check our Essential Korea Travel Apps guide for the full list of must-have navigation tools.

Option 4: Flight — Fast in the Air, But Factor in Airport Time
Flight time: Approximately 55 minutes Departure: Gimpo International Airport (Seoul) Arrival: Gimhae International Airport (Busan) Cost: ₩30,000–₩70,000 (varies by season and timing)
On paper, flying sounds like the fastest option. In practice, once you factor in getting to Gimpo Airport, check-in, security, boarding, and then traveling from Gimhae Airport into central Busan, the total door-to-door time is often comparable to — or longer than — the KTX.
That said, flights can be a great option when you find a cheap fare or are already near Gimpo Airport. Airlines on this route include Korean Air, Asiana, and several budget carriers.
Option 5: Rental Car — Maximum Freedom and Flexibility
Distance: Approximately 400km Travel time: Approximately 4–5 hours (including rest stops) Recommended routes:
- Gyeongbu Expressway (Route 1) — most direct, well-signposted
- Jungbu → Yeongdong → Gyeongbu Expressway — slightly longer but scenic
Toll fees: Approximately ₩25,000 (standard passenger vehicle)
Renting a car gives you the ultimate flexibility — stop wherever you like, detour through scenic countryside, and arrive in Busan with a vehicle ready to explore. It’s especially good for families or groups traveling together.
Things to Know Before Renting a Car in Korea
International Driving Permit (IDP) required: Foreign tourists must carry both their home country driver’s license and a valid IDP. Obtain yours before leaving home.
Major rental companies:
- Lotte Rent-a-Car
- SK Rent-a-Car
- AJ Rent-a-Car
- Hertz Korea / Avis Korea
Navigation: Use Naver Maps or Kakao Maps — both are far more accurate than Google Maps for Korean roads. Most rental cars include a built-in GPS system.
Toll payments: Most rental cars support Hi-Pass (electronic toll payment) for driving through toll booths without stopping. If yours doesn’t, you’ll pay cash.
Local Tip: Korean highway rest areas (휴게소) are a culture in themselves — don’t just stop to use the restroom! Try local snacks like Walnut Cakes (Hodu-gwaja) or Grilled Squid during the drive. Also, parking in Busan can be challenging in tourist areas, so check whether your hotel offers free parking before you arrive.
