Where to Camp
Pennsylvania has 2.2 million acres of state forest land with 2,500 miles of trails and 5,132 miles of
rivers and streams winding through it. Hiking, biking and multi-use trails traverse most state forest
districts and six districts have designated water trails that transect state forest land.
<span style="font-weight: bold">State parks are not open to primitive camping.</span> However, with the exception of William Penn
State Forest, all state forest districts are open to this activity. Camping is not permitted in designated
natural areas or at vistas, trail heads, picnic areas and areas that are posted closed to camping.
Contact a forest district office for specific information, maps and Camping Permits (if needed).
