Yes, boondocking, also known as dispersed camping, is legal in Michigan on public lands, such as national forests and some state forests. In Michigan, you can boondock in areas like the Huron-Manistee National Forests and the Hiawatha National Forest. There are also private properties available for boondocking through Hipcamp.
