Please be aware that part of the public area loop has been closed until further notice as the park starts preparatory efforts for this summer's paving project on the Picnic Area Road.
Natural Features & Ecosystems
The mountainous terrain of the Allegheny Mountain section of the Appalachian Plateau posed a problem to the Pennsylvania Mainline Canal, leading to the creation and use of incline planes that came to be known as the Allegheny Portage Railroad. The terrain-influenced form of transit, once novel and innovative for its time, is the backbone of the park’s history.
Did You Know?
In 1834, a passenger on the Portage wrote that the engine houses appeared "like fairy castles seated on the tops of lofty hills, and shaded and surrounded by towering oaks and hemlocks". Today, a new generation of hemlock, Pennsylvania's state tree, survives in Allegheny Portage Railroad NHS.
