Bigeum Valley is also known as “Mulgolan” (literally meaning inside water valley), as clean water flows abundantly in this area. The region is surrounded by the mountains of Seorisan, Chungnyeongsan, Jugeumsan, and Cheonmasan, and has several valleys. Bigeum Valley is located at the upper most region of Sudong National Tourist Park, and stretches for about 2 km. It is a popular vacation site, as thick forests provide cool shade and fresh, clean water runs through the scenic valley.
