Also referred to as Seolsan and Seolbongsan, the mountain was named Seorak (‘Seol’ meaning ‘snow’ and ‘Ak’ meaning ‘big mountain’) because the snow would not melt for a long time keeping the rocks in a permanent state of white. In November 1965, the Seorak Mountain district was designated as a Natural Monument preservation area. Afterwards in December 1973, it was designated as a park preservation area, and in August 1982, as a Biosphere Preservation District by UNESCO.
The park is spread across 4 cities and counties: Sokcho, Inje, Goseong and Yangyang. The highest peak is Daecheongbong; to the east is OeSeorak and to the west is NaeSeorak, which is divided again into North NaeSeorak and South NaeSeorak. North NaeSeorak is composed of Bukcheon, which flows to Ingyecheon and Baekdamcheon streams. There are numerous valleys in NaeSeorak. Follow the Baekdamcheon Valley where all the streams meet and you will reach Baekdamsa Temple, which is known for its beautiful scenery. Upstream there is Gayadong Valley and Suryeomdong Valley, and past Yeongsiam and Mangyeongdae there is Madeungryeong Ridge (1,327m) that leads to Seorakdong.
Follow Suryeomdong Valley and you will reach Waryong and Ssangpok waterfalls . Further up is Bongjeongam (1,224m sea level). Once you arrive at Daecheong Peak you can view the magnificent mountain range. The sunrise viewed from here is spectacular and should not be missed. South NaeSeorak directs the valley from Oknyeotang area to Hangyeryeong. Daeseung Waterfall north of Jangsudae is the most beautiful site of NaeSeorak, which is 88m high. South of Yongdaeri Valley is the Twelve Fairy Bathing Spring, Oktang Falls, and Yongtang Falls, along with several other traditional relics.
