National parks in Pennsylvania

Pennsylvania's National Park Service sites combine history and natural landscapes. Many units focus on the American founding era and the Civil War. Gettysburg National Military Park and Valley Forge National Historical Park, both in the southeast, feature battlefields and encampment trails that also serve as hiking paths. Further north, the atmosphere shifts. The Upper Delaware Scenic and Recreational River and Delaware Water Gap National Recreation Area provide river corridors and forested ridgelines, offering a sense of wilderness. Long-distance walkers can find quiet miles on the Appalachian and North Country National Scenic Trails, which cross the state. Hopewell Furnace represents an industrial-era site.
