Lynn Hollow

Lynn Hollow offers free public access to the Upper Mississippi River in the Upper Mississippi River National Wildlife and Fish Refuge near McCartney, WI. This is a well-maintained facility with free parking, outhouses, and typically light traffic—making it a good choice for paddlers and boaters seeking a less crowded launch. However, note that the access road passes under a low railroad bridge (7' 3" clearance), which may restrict vehicles with boats mounted on top.

The Mississippi River at this location is a major waterway with substantial current and flow. Expect swift water with an average velocity of 11.24 feet/second and significant downstream current, which is typical for the upper Mississippi. Paddlers should be prepared for strong flows and plan accordingly. The river is well-marked with mile markers and left/right designations to help with navigation and communication.

Before visiting, download the free Recreation.gov mobile app to access current conditions and facility information, particularly important given that periodic flooding can cause temporary closures. Cell service may be limited in remote areas, so downloading maps and information beforehand is recommended.
