The Lake Huron Circle Tour is one of four Great Lakes Circle Tours, each of which run through portions of Michigan. What sets the LHCT apart, though, is this route is the only one touching just two jurisdictions—Michigan and Ontario. The LHCT was officially designated soon after the debut of the Lake Michigan and Lake Superior Circle Tours. It joins the LMCT as one of the two which traverse both of Michigan's peninsulas as well as crossing the Mackinac Bridge.
