About Seoraksan
Seoraksan, rivalling Geumgangsan for its cliffs, valleys, springs and hot springs, is called the second Diamond Mountains and is the third highest mountain in South Korea. It became a national park in 1970, a UNESCO biosphere reserve in 1982 and an IUCN Category II protected area in 2005.
Its highest peak, Daecheongbong, divides the range: east of the line through Madeungnyeong, Misiryeong and Hangyeryeong lies Outer Seorak, toward the sea; west lies Inner Seorak.
Huge rock walls, deep gorges and old temples make it one of Korea’s great mountain landscapes.
