Kettle Moraine State Forest isn’t the best for road cycling, but it's worth locking up your bike and exploring on foot. This vast area, covering over 22,000 acres, boasts glacial hills, kettle lakes, and prairies. It offers more than 100 miles of trails for hiking, mountain biking, horseback riding, and nature walks. Enjoy paddling, boating, swimming, fishing, and hunting, as well as winter activities.
