Duncannon is one of the few official Appalachian Trail Communities and they are eager to share the pride and enthusiasm of being part of a national treasure. Join the community for a family-friendly festival while learning about the Appalachian Trail and other outdoor opportunities in Central PA.  There will be hikes and outdoor activities in the morning. In the afternoon there will be entertainment, exhibits, presentations, and vendors near the town square on High Street between Cumberland and Ann streets.
