Seowongyegok Valley is fed by the Samgacheon Stream, which originates from Songnisan Mountain and flows through Samga Reservoir in an S-shaped curve. It is relatively gentle in slope, and the stream is quite wide. The area is home to the 600-year-old Seowon-ri Pine Tree. Aside from enjoying the beautiful view of the area, one can also swim in the valley in summer.
