Hells Gate State Park

Hells Gate State Park is a public recreation area located on the southern edge of Lewiston, Idaho, at the Snake River's downstream entrance to Hells Canyon, the deepest canyon in North America. The state park was created by the U.S. Army Corps of Engineers to mitigate the construction of the Lower Granite Dam; the Idaho Department of Parks and Recreation began leasing the site in 1973. The park's 960 acres offer trails for hiking, mountain biking, and horseback riding as well as opportunities for camping, picnicking, fishing, boating, swimming, and taking jet boat trips into the canyon. The park sits at the lowest elevation of any Idaho state park, at 733 ft above sea level.
