About This Access Site
Located just outside Johnson Creek in Jefferson County, Rock River County Park provides a convenient public access point to the Rock River. The facility features a concrete boat/canoe ramp approximately 10-15 feet wide, making it suitable for kayaks, canoes, and small motorboats. The 4-acre park includes ample parking for vehicles and boat trailers, ADA-accessible restrooms and shelter, picnic tables, grills, and a flowing spring with cold water.

The Rock River shoreline at this access point has been stabilized with riprap, providing stable launch conditions. This quiet, family-friendly park is an ideal starting point for paddlers looking to explore the Rock River, whether for a short day trip or longer paddle. The combination of practical amenities—parking, restrooms, and picnic facilities—makes it a comfortable spot to prepare for your outing and enjoy the surrounding natural area.
