Five miles of the world-famous Appalachian Trail passes through Penn Township along the northern ridge of Cove Mountain just north of State Game Land #170. Notable points of interest are Hawk Rock Overlook and the Cove Mountain Shelter.
The Penn Township section of the Appalachian Trail starts south of Duncannon Borough where South Market and East Main streets meet by the Route 11/15 overpass. It continues south along Main Street, over the Sherman’s Creek bridge, along Inn Road and then turns right (west) heading up the end of Cove Mountain. Popular parking locations are near the end of Inn Road and near the end of Watershed Drive by the Recycling Center.
