The Rock River Water Trail is a water trail of the Upper Mississippi River Region and runs from its headwaters
above the Horicon National Wildlife Refuge in south central Wisconsin 330 miles to the confluence with the Mississippi River at the Quad Cities of Illinois and Iowa. The Rock River Water Trail crosses five counties in Wisconsin, six counties in Illinois and 37 municipalities, meandering down a gentle gradient to safely carry the water traveler and recreational enthusiast alike past picturesque rural and scenic landscapes, natural wilderness areas and vibrant urban riverfronts.
The Rock River Water Trail begins at two trailheads in the Wisconsin headwaters: Waupun County Park on the South Branch of the river in Waupun and Rivers Edge Park on the East Branch in Theresa. The water trail is known for its diversity and choice of landscape, vista and recreational experience and for its ease of accessibility. There are 32 signed access sites to the water trail in Dodge County.
In March 2013 the Rock River Water Trail was designated into the National Water Trails System by the Secretary of the US Department of the Interior. It is the first National Water Trail in Wisconsin and Illinois.
