Fort Atkinson and Jefferson Professional Review and Guide
"Jefferson County is an hour's drive from Milwaukee, proudly proclaiming that it lies along Wisconsin's Main Street: I-94. The county emphasizes that it is a year-round outdoor-lover's paradise, with fishing, hiking, cross-country skiing, and snowmobiling opportunities. One prime vacation draw is Lake Koshkonong, Wisconsin's second-largest lake, which covers 10,089 acres in south-western Jefferson County. The lake has long been a draw for day-trippers seeking some exciting water action.
The Rock River, which also flows through the county, provides additional recreational opportunities for those who enjoy canoeing. This eTrail from the DayTrips series describes many fascinating, exciting, (and many free of charge) things to do, most within a two-hour drive of Milwaukee. Each Day Trip includes destination highlights, places to visit along the way, choice restaurants and lodging, and shopping."
