Northern Michigan, and especially the western side are absolutely beautiful.
Make sure to hit up the Traverse City area. Some unbelievable scenery, great restaurants, and wineries.
In fact, if you’re into wineries, there’s some great winery tours up there. As you’re coming down the state try to hit up the sleeping bear sand dunes. Spectacular.
Not sure if you are into either golf or fishing, but that part of the country has some of the best fishing in the world and some of the most beautiful golf courses you will ever see.
