Cannon River Wilderness Area is an 850 acre park in Rice County. It stretches 4.4 miles along both sides of the Cannon River. Forested hills and ravines, riverbottom forest, steep bluffs, and sheer cliffs are found within its boundaries. There is a picnic area with toilet facilities, five miles of trails, four primitive campsites, and a wooden pedestrian bridge over the Cannon River. Until recently, a 20-acre section of this park was owned by The Nature Conservancy and managed as Cannon Wilderness Woods Preserve.
