When you travel in Seoul, you will take subway. Subway in Korean is 지하철(Ji ha cheol). The subway system in Seoul is very complicated and big. So If you don’t have a map, you will get lost! To be honest, I got lost several times at Chungmuro station. 😦
Here is some information about the subway system in Seoul. You can download those maps and bring them to Seoul.
