South Korea Transport

Get in

Air

South Korea has seven international airports, they are Busan(Gimhae Airport), Cheongju, Daegu, Jeju, Muan, Seoul(Gimpo Airport and Incheon International Airport), among of them, Incheon International Airport is the largest airport in Korea. There are also seven domestic airports, and a large number of heliports. South Korea is small enough that flying is more of a luxury than a necessity within the country, with the notable exception of connections to the island of Jeju. Korea’s own carriers are Korean Air and Asiana Airlines.

Train

Korail provides frequent train services to all major South Korean cities, two rail lines, Gyeongui and Donghae Bukbu Line. The Korean high-speed rail system, KTX, provides high-speed service along Gyeongbu and Honam Line. Major cities including Seoul, Busan, Incheon, Daegu, Daejeon and Gwangju have urban rapid transit systems. Tickets are much cheaper than in Japan but more expensive than other Asian countries. Buying tickets is fairly easy, self-service terminals accepting cash and credit cards are in multiple languages and are very simple to use.

Ferry

Korea has a very extensive network of ferries that connects hundreds of offshore islands to each other and to the mainland. The main ports include Incheon, Mokpo, Pohang, and Busan, the most popular destinations are Jeju-do and Ulleungdo. Busan Port International Passenger Terminal is the largest seaport in Korea and offers ferry rides mostly to and from Japan.
Get around

Bus

Buses remain the main mode of national transport, connecting all cities and towns, they're frequent, punctual and fast. There is a somewhat pointless division of long-distance buses into express buses and inter-city buses, which often use separate terminals to boot. In addition, local inner-city bus networks often connect directly neighbouring cities. In practical terms, express buses are marginally faster on long runs, but inter-city buses go to more places. For additional comfort, look for Udeung buses which have just three seats across instead of the usual four, but these cost about 50% extra.

Taxi

Taxis are a convenient, if somewhat pricey way of getting around the cities, and are sometimes the only practical way of reaching a place. Even in the major cities, you are extremely unlikely to get an English-speaking taxi driver, so it will be necessary to have the name of your destination written in Korean to show your taxi driver. Likewise, get your hotel's business card to show the taxi driver in case you get lost.
