The path over Yongmunbong is sparsely populated and has a series of dangerous ridges with sharp and steep slopes, but there are no safety measures such as markers or ropes.
Avoid when the rocks are wet or snowy.
Fortunately, I went on a clear day to see the famous pine trees on the summit of Yongmunbong, but it seems like you have to risk your life to see the snow-covered pine trees.
