Transportation
Public transporation in Korea is cheap, comprehensive, convenient and efficient.
Bus
There are two types of bus, express and intercity - the former go direct and the latter stop. Seats are reserved on the express buses (if you miss your bus, you must buy a new ticket), and unreserved on the intercity services.
The cost of an intercity bus ride is about 1000 won ($1). Buses can be a more direct way of travel and with the exception of rush hour periods more efficient as well.

Subway
South Korea has one of the most efficient and easy to use subway systems in the world. All signs are in English as well as in Korean and subway maps are posted in the stations. Standard subway fare is 800-1000 won (roughly $1) to go anywhere in the city or suburbs.

Train
Trains are clean, safe, punctual and inexpensive, and just about every station has signage in Korean and English. There are two different types of trains in Korea that will take you virtually anywhere in the country. The new world class KTX / Express Train travels at a speed of 300km/hr and will take you anywhere in the country within three hours. The average price of a regular train ticket to travel 2hrs is roughly 6 000 won ($6).

Car
Driving in South Korea can be difficult: it's expensive and traffic jams are a common problem. If that doesn't put you off, make sure you take an International Driving Permit.
