4 meters high and 20 meters long, there are no marked routes. This wall is part of a neighborhood park that includes skateboarding ramps. While technically in Osong in Chungbuk, it's just minutes walking from Chungnam. I rode my bike here from Jochiwon. Routes are limited by you imagination and skill. Most of the holds are pretty solid, with a few spinners (so next time I'll bring a wrench).
