KORAIL PASS
There is a train pass sold by Korea Railroad Corporation (KORAIL) for foreign visitors or foreign residents of Korea. These special tickets will allow unlimited travel on KORAIL-managed trains for a certain time period. There are no limits on the number of times you can travel or where you can travel during the duration of your pass.
The KORAIL Pass (also known as KR Pass) is exclusively for the foreign travelers' use. Each pass may only be used within the designated period of time, as specified by each ticket type.
The KORAIL Pass holders can make use of all railroad service offered by KORAIL (including the high speed KTX trains), following the usage period. One can choose to have the days from a single day to maximum of seven days in total, though, frequency of travel or the travel areas are not restricted. Please however, do note that terms and conditions of use may be limited depending on traveling period, such as during national holidays and/or summer vacation seasons, and may also require additional charge when boarding.
