Michigan's Thumb area river flowing through agricultural country, the Cass is a family-friendly paddle with gentle current and easy access. A pleasant introduction to paddling in the eastern Lower Peninsula. Its 95-mile course runs from gentle farmland meanders between Cass City and Caro down to wider, slower water reaching Saginaw Bay.
