Taebaeksan Mountain (태백산) encompasses several peaks such as Yeongbong Peak, where in the past, people would conduct rites to venerate Heaven at Cheonjedan, Janggunbong Peak (1,567m) and Munsubong Peak (1,517m). The mountain is rather high but easy to hike since it is relatively smooth and has few cliffs. The higher plains are covered with alpine vegetation. The mountain becomes hot pink with mountain rhododendron and azalea in the spring; green with thick forest and pristine waters in the summer; rainbow colored with changing leaves in the fall; and white with snow in the winter.Taebaeksan Mountain is one of the three sacred mountains of Korea and the sunrise observed at Cheonjedan is simply breathtaking. There is a ritual site for Dangun in Danggol Valley, where people celebrate Gaecheonjeol (개천절) each year; and there are a number of Buddhist temples such as Manggyeong, Baekdan, Yuil and Cheongwon. Right below the mountaintop lies Yongjeong, the well that is said to boast the very best-quality water among the 100 good water sources in Korea. Near the park are located Geomryongso, the origin of the Han River, and Hwangji Pond, source of the Nakdonggang River. The Taebaek Coal Museum and Gumunso Natural Experience Field provide visitors with information on fossils, geology and the development of the coal industry.* Sunrise at Mt. TaebaeksanWeather permitting, you can watch the sun rising out of the East Sea from the top of Mt. Taebaeksan (Cheonjedan). It usually first appears breaking through the clouds or peeking between the mountaintops. In order to watch the first sunrise of the year at the top of Mt. Taebaeksan, you need to equip yourself with a wintertime hiking outfit and tools such as crampons and a headlamp. Since Mt. Taebaeksan is not far from downtown Taebaek, it is convenient for hikers to spend the night Taebaek and get to the mountain by land transportation.
