Boondocking, or camping without amenities in undeveloped areas, is not illegal in Pennsylvania as long as it is done on public lands that permit dispersed camping. In Pennsylvania, you can boondock on state forests and some national forests, such as the Allegheny National Forest, where dispersed camping is allowed. However, it is essential to follow the guidelines and regulations set by the respective land management agency. Boondocking is allowed in designated or non-designated areas, but make sure to practice Leave No Trace principles and adhere to any posted restrictions or rules. Boondocking on private property without permission is illegal. If you are looking for more secluded camping options in Pennsylvania, you can also check out Hipcamp for private land camping.
