In Michigan, you can often camp for free in designated areas or dispersed camping zones within its national forests, such as the Hiawatha National Forest and the Huron-Manistee National Forest. However, some areas may require fees or permits. These forests offer dispersed, primitive camping with no facilities. You'll need to come prepared and follow Leave No Trace principles. Additionally, some state forest lands also allow free dispersed camping, but it's essential to check the specific regulations for each area before setting up camp.
