Yunsan is a 317m peak near Busandae Station in Busan. A trail runs from Bugokam through a loop path to the summit, with views over Busan from Hoedong Reservoir out to Gwangandaegyo. The round trip takes about 1 hour 30 minutes, starting from the Bugokam parking lot or from Exit 4 of Busandae Station along the alley by Bugok Middle School. Benches and rest areas sit along the route, and the many stairs and steep uphill sections make parts of the climb demanding.
