Olsan Mountain towers in the center of the deep mountains, north of Olsan-ri, Daegang-myeon.

Olsan Mountain(858m) is a ranching area with many native plants and a large summit, so it looks like a foreign winter landscape in winter, and the mountain terrain is deep and has abundant water.

There are many peaks, including Ttoek Rock, OB-GYN Rock, and Rainbow Rock, and various species of plants, including wild greens and medicinal herbs, grow on the mountain. The mountain is easy to climb, with many oddly shaped rocks that will give you a sense of delight as soon as you enter the trail.
