Sunbury, originally home to the Susquehannock, Delaware, Shawnee, and Muncy tribes, was incorporated in 1772 and is the seat of Northumberland County. The town is the birthplace of office lighting - Thomas Edison illuminated a Sunbury commercial building with his three-wire electrical system in 1883. Visitors to Sunbury today leave the office behind for the amenities of Shikellamy State Park, which boasts paved trails, picnic areas, and a marina on Lake Augusta. Blue Hill, across from the marina, provides panoramic views of the Susquehanna River. Covered bridges, fishing, camping, and a yearly Riverfest make Sunbury a great place to visit.
