Heyburn State Park is the oldest state park in the Pacific Northwest, established in 1908 in Benewah County, Idaho’s panhandle, managed by Idaho Department of Parks and Recreation. The park encompasses three lakes — Chatcolet, Benewah, and Hidden, featuring camping with cabins and cottages on the shores of Chatcolet Lake, boating and water sports on all three lakes with marina and boat ramp facilities, the St. Joe River — widely considered the world’s highest navigable river — flowing through the park, fishing for largemouth bass, crappie, perch, and northern pike, hiking and mountain biking trails through old-growth western red cedar and ponderosa pine forest, a trail of the Coeur d’Alenes paved pathway for cycling, swimming beaches on Chatcolet Lake, and a 5,744-acre park that preserves one of the finest lake-and-forest landscapes in the Idaho panhandle.

The St. Joe River is a geographic marvel — classified as the world’s highest navigable river, it flows at 2,129 feet elevation through the park before entering Chatcolet Lake. Paddling this pristine mountain river through old-growth forest is one of Idaho’s most unforgettable water experiences.

Being the oldest state park in the Pacific Northwest gives Heyburn a storied history — President Theodore Roosevelt signed the legislation creating the park in 1908, recognizing the extraordinary beauty of these interconnected lakes and forested mountains deserved permanent protection.
