I went with Kok Yong on the 5th day of the trip, its the 3rd highest mountain in Korea, with main activities hiking, camping and climbing. There's a short cable car trip available to the top as well, tho it wasnt included in our tour package
We had to climb a trip up the mountain which involves walking and stepping on snow, a new experience for me.
Here are some pics i took, the fountain was taken when we finally reached the end of the hike, hope you guys like them :)
