Greenwood Furnace State Park
The park is on the western edge of the Seven Mountains in northeastern Huntingdon County, an area of rugged beauty, abundant wildlife, breathtaking vistas, and peaceful solitude. Greenwood Furnace State Park covers 423 acres, including a six-acre lake, campground, hiking trails, and a historic district. The park provides access to backpacking, hiking, mountain biking, hunting, and fishing in the surrounding 80,000-acre Rothrock State Forest.
A walk through historic Greenwood Furnace evokes images of the community that flourished here from 1834 to 1904. Greenwood Furnace was a busy industrial complex, with all the noise and dirt of a 19th century ironmaking community. The village throbbed with life: the roaring of furnace stacks, the shouts of the workmen, the hissing of the steam engine, the creaking of wagons loaded with charcoal, and the cast house whistle signaling another pour of molten iron. The furnaces were hot (3,000 degrees Fahrenheit) and cast clouds of smoke and cinders into the air, which rained down on grass, people, livestock, and buildings, rendering everything sooty and gray. At night, the fire’s red glow lit the sky, probably allowing residents to walk about without lanterns. Greenwood Furnace was a village built around an inferno.
The park office is open 8:00 AM to 4:00 PM Monday through Friday year round, and daily during the summer.
Picnicking: Picnic tables, eight reservable picnic pavilions, and modern restrooms are in a spruce and pine grove close to the beach. Unreserved pavilions are free on a first-come, first-served basis. A playground, snack bar, horseshoe pits, volleyball courts, and a ball field make this area popular for picnics and reunions.
Snack Bar: A food and refreshment concession near the beach serves visitors in the summer from Memorial Day to Labor Day weekend.
