Hanna Mountain is a famous mountain in South Korea. You must climb once to Jeju Island. There are several paths for mountaineering, and there are difficulties. It is recommended to do your homework before coming, reserve enough time, bring dry food and water, and sell nothing on the mountain! We went up the mountain from Lingshi, Yuli Mu went down the mountain, the whole climbing process was smooth, most of the roads were better to walk, that is, there were more stone roads down the mountain. There was no car at the bus station that day. Fortunately, there was a Korean brother who sent us a trip. Thank you Korean brother!
