John Muir Trails

High-quality single-track mountain bike trail system within an hour Madison and Milwaukee and two hours of Chicago make these trails the most popular in the state. Add top-notch trailhead facilities, ample rider services in area communities, plus the attractions and hospitality of the region and you've got an unbeatable riding destination. A big part of the attraction is one-way trails in the challenging terrain of the beautiful Kettle Moraine State Forest. The one-way trails make the experience seem almost private. You may pass or be passed by a few people, but you won't believe you're sharing the trails with a thousand other riders. The rugged terrain, hills and kettle-like depressions make for some tough riding, and may not be for everyone. But for riders looking for challenging, technical riding - this is the place. These trails are not suited for road or touring bikes, or bikes with trailers. During the winter, these trails are open to hikers and snowshoers. Fat-tire bikes do use this trail in the winter as well. A state park vehicle sticker is required.  Anyone 16 years and older riding a mountain bike will require a state trail pass as well.
