Sobaeksan National Park in South Korea is a branch of what could be called the backbone of Korea, Taebaeksan Mountain. In 1987, Sobaeksan Mountain was designated as National Park No.18. Its covers an area of 320.50 square km. The features of Sobaeksan National Park include wild flowers and royal azaleas on Birobong Peak, and the largest yew tree community is found on the northwest slope (1,200-1,350 m above sea level) between Yeonhwabong Peak and Birobong Peak. The west of Mt. Sobaeksan is steep, and streams from Nakdonggang River flow to Jukgyaecheon River, which is often used as a hiking course. Following down from Birobong Peak along Jukgyaecheon River is Seokryun Mine and Choamsa Temple. If you proceed even further, you will get to Seokcheonpokpo Falls and Seonghyeolsa Temple. Many trout live in this valley. A 4-km flat path to the southwest of Birobong Peak leads to Yeonhwabong Peak. There is Sobaeksan Optical Astronomy Observatory (SOAO) on the way to the second Yeonhwabong Peak, and a ridge called Jukryeong is on the south side of the mountain. To the east of the second Yeonhwabong Peak, there is Huibangsa Temple and Birosa Temple, both built during the time of the Silla Kingdom. Huibangpokpo Falls is considered the most beautiful waterfall of Gyeongsangnam-do Province, and is at the entrance of Huibangsa Temple. Featuring beautiful valleys and ridgelines, Sobaeksan National Park is known for its abundant wildlife and breathtaking nature.
