A favorite tour for motorcyclist is the State Highway M-25. It’s a 147 mile road running from Port Huron to Bay City Michigan. With waters of Lake Huron or Saginaw Bay on one side and rolling pasture and farmland on the other it’s one of the more interesting drives in southern Michigan.
Officially M-25 is a state trunk line highway in the US state of Michigan. M-25 is part of the Lake Huron Circle Tour for its entire length. Starting at a junction with Business Loop I-69/Business Loop I-94 in Port Huron running north along the coast the highway passes through Lexington, Port Sanilac, Harbor Beach and Port Hope. At Port Austin is the northern most point of M-25. From here the road turns west and south running through Caseville, Bay Port, Bay, Unionville and ending in Bay City. The section of M-25 in Bay City was named what is now called a Pure Michigan Historic Byway by the Michigan Department of Transportation (MDOT). Originally called the Bay City Historic Heritage Route you can see historical neighborhoods and large Victorian homes constructed by the lumber barons of the 1800s.
