Baemsagol is the signature valley of Mt. Jirisan's northern face, running roughly 14 kilometers from Banseon Village in San-nae-myeon, Namwon, up toward the base of Banyabong Peak. Counted as one of Jirisan's three major valleys, it's known year-round for its scenery, its legends, and its trekking routes. The valley is made up of broad flat rocks — some wide enough to seat over a hundred people — along with dozens of waterfalls of every size and clear pools throughout, giving it the feel of a landscape painting brought to life.
The name "Baemsagol" carries an unsettling legend. According to local folklore, a giant serpent-like creature that had been devouring Buddhist monks died in this valley, and the blood it shed is said to be the origin of the valley's name. In spring, azaleas color the slopes; in summer, dense greenery and cool mountain air offer relief from the heat; in autumn, the cliffs turn a brilliant red; and in winter, snow adds yet another kind of beauty. Jirisan National Park generally restricts entry into its valleys, but during the peak summer season (through August 31), the section from Banseon Bridge to Seonindae is opened to visitors. Where legend once placed a monster that preyed on people, visitors now wade in to cool off from the summer heat.
