Seoraksan is the highest mountain in the Taebaek mountain range in the Gangwon Province in eastern South Korea. It is located in a national park near the city of Sokcho. After the Hallasan volcano on Jeju Island and Jirisan in the south, Seoraksan is the third highest mountain in South Korea.The national park attracts many national and international tourists all year round, but the main season for Seoraksan national park is autumn. The autumn colours in the area are considered amongst the most beautiful in Korea. The red and yellow forest is interrupted by rocks and small mountain streams flow amidst this.Perhaps the most visited part of the mountain is the main entrance valley to the National Park, a fifteen-minute drive from Sokcho city. The valley runs west to east with a paved road leading up to the park’s entrance gate. This valley contains many beautiful sites and is well worth a day visit.At the end of the main valley is Biseondae, a rock platform in a stream. Above the stream is a difficult to reach cave, which offers clear views of the surrounding rock formations.A bit farther from the entrance is the Valley of a Thousand Buddhas, the primary valley of Seorak Mountain, also sometimes referred to as Seorak Valley. The valley was so named because the rock formations that line its sides resemble a line-up of Buddha statues.
