Located in Odaesan National Park, Sambong Recreational Forest (삼봉자연휴양림) is filled with large acicular trees like fir and broad-leaved trees like birch. Lenoks, a species of fresh-water fish that are considered a Korean natural treasure, found only in the cleanest water, thrive in the waters of the deep valley running through the park. The park is surrounded by three peaks – Gachilbong (1,240m), Mt. Eungboksan (1,155m), and Sasambong (1,107m). In the middle of the area surrounded by the three peaks, rests the Sambong Mineral Spring (삼봉약수), whose waters attract many visitors. The spring’s waters are said to ease stomach complaints. The park is also popular since visitors can go leaf peeking in autumn while enjoying the mountains and sea at the same time in summer.
