There are plenty of hiking opportunities around Danyang, especially in the nearby Sobaeksan and Woraksan National Parks. The easiest option, though, is to head to Mount Daesong Daesongsan, 380m, located right behind the city and covered with easy, well-signposted in Korean hiking trails, the main one doing a loop around the base of the hill. There are several trailheads; to reach the most convenient one, walk up the hill from the bus terminal, then turn left after the police station. The "summit" is about 1 km away.
