Unmunsan National Recreational Forest in Cheongdo, Gyeongsangbuk-do is located at the foot of Unmunsan Mountain (1,188 meters), which is also called Hogeosan Mountain. It is a great place to spend time in summer for hiking and camping, surrounded by taller mountains (more than 1,000 meters above sea level) such as Munboksan Mountain (1,014 meters) and Gajisan Mountain (1,240 meters).

Yongmipokpo Falls (20 meters) and Byeokgyesu Valley, in which the waters flow across the sandless rock bed, are famous locales in the forest. Located in a thick broadleaf forest, inhabited by many diverse species such as Korean mountain camellia, Unmunsan National Recreational Forest offers lush greenery in summer, beautiful foliage in autumn, and cozy, splendid snowscapes along with the Yongmi Ice Wall in winter. In Unmunryeong, located 2.5 kilometers to the east, visitors can watch the spectacular sunrise above the East Sea.
