Circumnavigation route of Lake Michigan.
Lake Michigan is the third largest lake in the United States and borders four states: Illinois, Wisconsin, Michigan, and Indiana. Lake Michigan is also the only Great Lake located entirely in the United States.
Note that the route is up to you, and you just need to circumnavigate the lake, and start and end at the same spot. The route on our map shows one option that generally stays close to the lake, but clearly is not the shortest route.
Steve Cannon wrote a book about his 40-day run around Lake Michigan in 2012.
