The Wiouwash State Trail is named for Winnebago, Outagamie, Waupaca and Shawano counties. This trail, built on a former rail corridor, is maintained and operated by the four counties the trail traverses. Two sections of the trail are now complete and are separated by a gap of about 30 miles.

In Shawano County, the northern segment of the trail travels 19 miles between Birnamwood and Split Rock. This segment of the trail connects with the Mountain-Bay State Trail in Eland. The southern segment of the trail is open for 22 miles from Hortonville to the city of Oshkosh. The southern segment skirts along the edge of Lake Butte des Morts and continues into the countryside through native tall grass prairies, farmlands and wildlife areas. This segment connects to the Friendship Trail at State Highway 10. The Friendship Trail travels between the Wiouwash State Trail and the city of Menasha.

The level grade and limestone surface make this trail suitable for bicyclists, walkers and joggers. Two segments of the trail corridor are open for horses. Cross country skiing and snowmobiles are permitted on the trail in the winter.
