Kinnickinnic River State Natural Area Adventures

Kinnickinnic River State Natural Area (SNA) is located in northwestern Wisconsin, following a 22-mile stretch of the Kinnickinnic River, one of the state's premier cold-water trout streams. The area preserves critical habitat for native brook trout and brown trout, supported by the river’s exceptionally clear, cold water sourced from groundwater springs. The landscape is characterized by forested riverbanks, rocky rapids, and a mosaic of hardwoods including oak, maple, and pine. Historically, the Kinnickinnic River valley has been inhabited and used by Native American peoples, and later by European settlers for agriculture and milling. The SNA designation ensures the protection of this vital riparian corridor, maintaining high water quality and diverse biological communities. Outdoor enthusiasts often seek the area for fly fishing—considered some of the best in the region—along with kayaking and canoeing in the calmer stretches of the river. Hiking and nature observation are popular along limited trails and the riverbanks, where visitors can spot native wildlife such as herons, kingfishers, and beavers. The natural area’s appeal lies in its unspoiled riverine environment, providing a quiet and immersive wilderness experience close to the small communities nearby. The Kinnickinnic River SNA complements adjacent county parks and preserves, creating a broader landscape for conservation and quiet outdoor recreation.
