Tongyeong is a coastal town in the south part of south Korea.  It is to the west of Busan by about 1hr 30m drive.  We took two trips there.  One a day trip just to climb and another to climb and be tourists.  There is really good rock there by the routes are very run out and scary.  A big mental battle has to be fought each route.  I found myself cheating a lot and pulling on gear to get to the top which is never a good thing.
