Odaesan National Park (오대산국립공원) was designated as a national park in 1975. Its name was derived from the the following 5 plateaus: Manwoldae, Jangryeondae, Girindae, Sangsamdae and Jigongdae.
Featuring the 1563m high Birobong Peak, Odaesan spreads southwest with Mt. Sodaesan, Horyeong Peak and Mt. Sogyebangsan. The east side is connected with Sangwang peak and Duro Peak, which are over 1,000m high. The representative temple of Odaesan, Woljeongsa Temple, was named after the bright, full moon that rises above Manwoldae (Mt. Dongdaesan). At this temple the famous Octagon shaped 9-story pagoda (National Treasure No.48) and the Stone Seated Buddha Figure (National Treasure No.139) is preserved. Also, Jeokmyeolbogung of Woljeongsa is where Monk Ja Jang preserved the Sakyamuni's noble relics. Inside Woljeongsa Temple, follow the fir trees 5 km east, and you will reach Sagoji where Yeonggamsa Temple stands. Odaesan has the largest natural woods of Korea. Many wild animals and plants are known to exist here. The area of Birobong is famous for its Nuncheunkbaek and Yew tree forests. The royal azelea and Geumgang Chorong from Duro peak to Sangwang Peak are famous and there are animals such as boars, musk deer, turtledoves and colorful woodpeckers living here.
