The Red Cedar Bike Trail. This trail shadows the steep walls of the Red Cedar Valley for 14.5 miles from Menomonie to its connection with the Chippewa River State Trail. Along its route, the Red Cedar trail passes through the communities of Irvington and Downsville and the Dunnville State Wildlife Area.
Depending on how you link up the trails, the rim-to-rim (R2R) hike is about 24 miles (38 kilometers). The R2R hike is divided roughly into three parts. On each end is the steep hike out of the canyon and the middle third is a more moderate and smoother hike through a side canyon that is spectacular in it's own right.
