The valley originates from the slopes of Mount Gongjisan, which stands at an elevation of 889 meters in Hongcheon County.
Sutasa Temple, located at the head of the valley, was originally founded in the year 708 during the Silla Dynasty by Monk Wonhyo under the name Ilgapsa.
The temple housing the valley was later renamed Sutasa in the Joseon Dynasty, translating literally to 'Wash Head Temple', derived from a local legend about washing impurities.
The stream flowing through Sutasa Valley is a designated habitat for several protected freshwater fish species native to Korea's Gangwon region.
The walking trail along the valley connects to a larger ecological path network managed by Hongcheon County for low-impact eco-tourism.
Sutasa Valley is a scenic natural canyon located in Deokchi-ri, Yeonggwimi-myeon, Hongcheon-gun, Gangwon-do, South Korea, renowned for its crystal-clear water and dramatic rock formations. The valley stretches outward from the historic Sutasa Temple, offering visitors a blend of pristine natural scenery and centuries-old Buddhist heritage. Smooth granite boulders, carved by rushing mountain streams, create numerous natural pools along the riverbed. A well-maintained walking trail, known as the 'Walking Path of Thousand Years', runs alongside the stream, making it accessible for casual hikers. The surrounding forest features dense growths of pine and deciduous trees that undergo dramatic transformations across all four seasons. During peak autumn foliage, the valley floor and surrounding slopes become vibrant with red and gold hues. In the summer months, the shaded canopy and cold valley water attract travelers seeking relief from seasonal heat. The area also serves as the starting point for trekking routes leading up toward the nearby Gongjisan mountain. Preservation efforts keep the natural habitat largely undisturbed, allowing native freshwater fish and plant species to thrive in the stream.

Wear sturdy walking shoes with good grip, as the granite rocks near the stream can be slippery when wet.
Bring insect repellent and drinking water, as facilities are concentrated near the temple entrance rather than deep in the valley.
Visit early in the morning during autumn weekends to secure parking and experience the trail without heavy crowds.
Swimming in unauthorized or restricted sections of the stream where water currents are strong or conservation rules apply. Leaving trash behind; visitors must carry out all personal waste as public bins are limited along the trail.
Respect the surrounding Buddhist temple grounds by dressing modestly and keeping noise levels low near the valley trail.
