The gently rolling B.A.T.S. – Crystal Lake Trail (Boulder Junction Area Trail System) lets bicyclists enjoy all the scenic beauty without any of the traffic hassles on the county highways. It starts in Boulder Junction and is 13 miles one way, passing by Trout Lake and Crystal Lake. Free parking and a beautiful trail.
This 18-mile railbed trail offers a packed granite gravel surface for biking. Excellent birding as the trail transects varied habitats, hardwoods, bogs, old-field, marsh and springs, and trout stream. The south end of the trail is especially productive. Numerous trestles and boardwalks provide viewing stops and fascinating interpretive signage. The trail begins right outside of downtown Mincoqua. There is plenty of parking and many retail stores and restaurants near by.
