Boondocking, or camping without amenities on public lands, is not illegal in Tennessee as long as the land allows for dispersed camping. However, it's important to follow the specific rules and regulations of the area you're camping in. Some public lands, like national forests, may permit boondocking in designated areas, while others may not. Always check with the land management agency responsible for the area you plan to camp in to ensure you're following the rules. Private landowners may also offer boondocking opportunities, such as Bryson's Boondocking on Hipcamp. In these cases, you'll need to obtain permission from the landowner and follow their guidelines for camping on their property.
