Are there any other options for travelling from Seoul to Busan?

You can fly or drive between Seoul and Busan, but we wouldn’t recommend either. Flying is expensive, and travel times to and from airports plus minimum check-in times means it’s not much quicker than a bus or a traditional train. Driving is expensive and a major hassle.

Getting from Seoul to Busan by plane

Frequent flights between Seoul’s nearby Gimpo International Airport (GMP) and Gimhae International Airport (PUS) in Busan take about one hour. There are also flights from Incheon International Airport (ICN), Seoul’s main international airport, which is more than an hour from the city, but these are mainly connecting flights from other countries.

The cheapest way is to get the subway to GMP airport and then a bus into Busan at the other end (route details below). Otherwise you can easily catch a taxi on either side of the flight.

From central Seoul to GMP by subway
GMP airport is on Seoul’s comprehensive subway system. From central Seoul, trains are frequent and take about 20 minutes on the Arex (airport express) fast train.

From GMP to PUS by plane 
Airlines flying the route include the big international airlines Asiana and Korean Air plus budget carriers Air Busan and Eastar Jet. Flight time is about one hour.

PUS to central Busan by bus or subway
Several buses link the airport to central Busan; service is frequent although the trip can take up to one hour at rush hour. The English-speaking information desk in the airport’s arrivals area can help you decide which bus to take. Note: you can also take the light rail to Sasang station in the city, for further subway connections.

Getting from Seoul to Busan by car

South Korea has a well-deserved reputation for being a challenging place to drive. Drivers only selectively obey road laws, while signage and the road layout in and around cities can be deeply confusing.

  • One-day car hire starts at about US$80 per day through major car rental firms when the car is returned to the place of rental
  • One-way car rental from Seoul to Busan costs from US$250 per day
  • Driving takes about 4.5 hours, if you don’t get lost

The island also offers beautiful beaches, stunning waterfalls and some breathtaking hiking trails.

Getting from Busan to Jeju Island

Flying is by far the quickest option. The flight time from Busan to Jeju Island is just under an hour with Jeju Air and Air Busan both offering frequent daily flights. However, if you already have a hire car in Busan and intend on using it to explore Jeju island then taking the overnight ferry from Busan to Jeju can be a good option. The ENA CarFerry takes around 12 hours, offers comfortable cabins and has approximately three sailings a week.
