Before last summer for first time i used bus for going out to Boryeong Mud Festival and this year i used bus again for another festival HAHAAHA maybe before you read this http://hanachrisantyjioe.blogspot.com/2015/07/korea-express-bus-terminal.html but now i used another bus terminal.
Located in East side of Seoul that's why this called as DONG ( EAST) SEOUL TERMINAL. So from here you can also go to many destination and also if you lazy using train to Nami island you can go from here but more expensive.
This terminal i guess it old terminal because it's not too big and clean compared with express bus terminal whichis very fancy.
How to go here :
Get off GANGBYEON MRT STATION ( line 2) exit 4
Bus ticket price :
