KTX routes and stations

• Main routes: KTX runs across the country, including the Gyeongbu Line (Seoul-Busan), Honam Line (Seoul-Mokpo), Jeolla Line (Iksan-Yeosu), and Gangneung Line (Seoul-Gangneung).
• Major stops: Seoul Station, Yongsan Station, Gwangmyeong Station, and Gwangju Station. In the provinces, Busan Station, Dongdaegu Station, and Gwangju Songjeong Station are the main stations. Check the stops on the Korail website.
• Transfer station information: Seoul Station and Yongsan Station are connected to the metropolitan train for easy transfers, Busan Station is connected to Subway Line 1, Dongdaegu Station is connected to Lines 1 and 2, and Iksan Station is convenient for bus transfers.

Top tips for travelling on KTX

• Advance seat selection: You can only select your seat at the station until 15 days after the train opens. If you have a preferred seat, such as a window or inside, book it at the station.
• Arrive at the station: KTX departs on time, so arrive at the station with plenty of time to spare. At larger stations, it can take a while to get to the platform, so try to be there at least 20 minutes before departure.
• Baggage policy: Each passenger is usually allowed up to the amount of luggage they can carry themselves. You can bring up to two suitcases.

Foreigner Bus, Take a leisurely ride on an inexpensive intercity/express bus

Reservations and fares for foreign express buses and intercity buses

• Tickets in person at the terminal: For intercity and express buses, tickets can be purchased at the bus terminal ticket window on the day of departure. English-speaking agents are available, just ask.
• Online/mobile booking: You can book on the Kobus website and app. Search for “kobus” in the Google Play Store.
• Fare information: Bus fares are based on distance: Seoul-Busan is in the $30-40,000 range, Seoul-Gwangju is in the $20,000 range, and late night and peak periods are surcharged. The more luxurious limousine buses(Woodeong Bus) cost a bit more. However, if you want to travel conveniently, I recommend using the limousine bus rather than a regular bus.

Intercity/highway bus terminal information nationwide

• Seoul terminals: Seoul Express Bus Terminal (Gyeongbu Line), Dong Seoul Bus Terminal (Yeongdong Line), and Sangbong Terminal (Gyeongui-Jungang Line), which are connected to the subway.
• Major city terminals: Busan Bus Terminal, Daegu Express Bus Terminal, Gwangju Bus Terminal, etc. You can board at the intercity bus terminal in each city.
• Smaller city terminals: In smaller cities without terminals, there are intercity bus stops. Check the location of the stop in advance and check the frequency of the bus.

Things to keep in mind when travelling by bus

• Check your boarding time: Make sure to check your boarding time when booking. Unlike domestic flights, buses don’t have reserved seats, so it’s best to board at least 20 minutes before your departure time.
• Stop at rest stops: Long-distance buses stop at rest stops for 15-20 minutes. Allow enough time for your arrival to rest, and you can buy some snacks.
• Luggage note: You can carry your luggage in the boot of the bus, but leave valuables on your seat as they are at risk of breakage and you can’t see them.

Foreigner Airlines, take a convenient domestic flight to Jeju Island

Book a domestic flight

• Choose an airline: Asiana, Korean Air, Jeju Air, Air Busan, Jin Air, and T’Way all fly domestic flights. Look out for low-cost airline deals.
