Heyburn State Park is the oldest park in the Pacific Northwest. Created in 1908, it is comprised of approximately 5,500 acres of land and 2,300 acres of water. The park includes three lakes; Chatcolet, Benewah, and Hidden Lakes, with the shadowy St. Joe River meandering along the eastern boundary of the park.

Fish for pike, bass, or pan fish in the lakes. Bird watching is terrific at Heyburn, with osprey and blue heron as common as sparrows back home. Boating, water skiing, sailing and canoeing are also popular pursuits. Trails for hikers or horseback riders are shaded by 400-year-old ponderosa pines. The Rocky Point Marina offers a public boat ramp, store, fuel dock, restroom and parking.
