BARABOO â No Wisconsin state park is more popular. With its towering bluffs, miles of hiking trails, hundreds of campsites and a clear, cold lake that attracts anglers, swimmers, paddlers and scuba divers, Devilâs Lake State Park is an amphitheater of outdoor recreation. Add in the fact that itâs just a 45-minute drive up Highway 12 from Madison and less than three hours from Chicagoâs western suburbs and itâs no surprise that the parkâs 1,300 day-use parking spots and 1,300 picnic tables are often all claimed by early afternoon between Memorial Day and Labor Day. Miles of trails traverse the West and East bluffs of Devil's Lake State Park, opening to breathtaking views such as this one of the Devil's Doorway rock formation at the southeast corner of the lake.Â
