The Tri County Corridor is an old railroad grade between Ashland and Superior, Wisconsin. While it is not a Forest Srevice trail, it provides an important link to towns around US Highway 2. This trail is paved with crushed limestone. The rest of the ATV trails are on gently rolling to hilly terrain forested with aspen, jack pine, red pine and oak. A majority of the trail tread is sandy. These trails are designated dual use routes for both ATV's and snowmobiles. These trails are a good place to ride in wetter weather. Dog sleds and horses are prohibited from using these trails.
