The Saginaw Bay Birding Trail covers a total of 142 miles, including Michigan Highways M-25 and M-13, as well as 40 miles of the US-23 State Recreation Byway (Standish to Tawas). The Trail runs from Port Austin on the eastern end to Tawas Point State Park on the western end, and largely follows the shoreline of the entire Saginaw Bay. The distinct change in seasons, diverse habitats, sprawling miles of shoreline, plus extensive natural areas with public access make the Trail a birder’s paradise! (Courtesy SBBT’s Facebook page.)
Maps of four different trail areas can be found here.
