Jefferson County, Wisconsin

Jefferson County is halfway between Milwaukee and Madison. The Rock and Crawfish Rivers wind through the landscape. Lake Mills is known for its quaint downtown and popular state park.
Fort Atkinson draws historians with its reconstructed 19th-century fort. The Glacial Drumlin State Trail is a hit with cyclists and hikers. Dairy farms fill the countryside, a reminder of Wisconsin’s agricultural roots.
While fall brings pumpkin patches and corn mazes, winters can be harsh. But that doesn’t stop locals from ice fishing on Lake Koshkonong. It’s a place that offers a little bit of everything.
