Winnebago County, Illinois
Winnebago County sits in northern Illinois, right up against the Wisconsin border. Rockford, the county seat, is the state’s fifth-largest city. It’s a hub for manufacturing and healthcare in northern Illinois.
The Rock River cuts through the heart of the county, including through Rockford. This scenic waterway provides plenty of opportunities for fishing, boating, and riverside parks.
There’s more to do here than in most Illinois counties. Rockford has museums, parks, and a decent food scene. But step outside the city, and you’re in small-town America.
