The valley serves as the headwaters of the Geumgang River, one of South Korea's major waterways.
The name 'Mulhan' translates to 'water becomes cold,' referencing the year-round low temperature of the stream.
The surrounding Minjujisan Mountain is part of the Sobaek mountain range and reaches elevations over 1,200 meters.
The valley is officially designated as part of a forest recreation area aimed at protecting the local ecosystem.
It is a popular location for observing the transition of forest colors during the autumn season due to the variety of deciduous trees.
Mulhan Valley is a pristine natural valley located at the base of Minjujisan Mountain in Yeongdong, South Korea. The valley stretches approximately 20 kilometers, beginning from Mulhan-ri and extending upward toward the mountain peaks. It is characterized by its clear, cold water, dense forests, and rocky riverbeds that remain cool even during the peak of summer. The area is a key starting point for hikers trekking toward the summits of Minjujisan, Gaksibong, and Seokgibong. The valley floor features numerous natural rock pools and flat boulders suitable for wading and resting. Because of its location in a mountainous basin, the air temperature is significantly lower than in nearby urban centers. The site is a managed natural recreation area with designated zones for ecological preservation. It serves as a habitat for diverse flora and fauna, including rare mountain plants.
