Hiking the Seorak mountain - 2 The highest peak of Seorak Mt. is called 'Daechungbong'. It is a high peak as third in South Korea and 1,708m above the sea level. Usually there are three trails leading to the top of this mountian. The first course is named 'Osek' which is the shortest distance, 9km but the most hardest among the other courses. This course starts to the hiking information center of south Seorak Mt. The second course is named 'Hangaeryung' and starts to the Hangaeryung rest area. It is the relatively easy way because it is located at an altitude 1.004m. The total distance is 14km. The last course is called 'Bekdamsa' which is located in the north of mountain. The total distance is 24km and the longest in the three ways. But I think that this way is the most easiest way to the peak because it is a ridge way following the vally.
