Greenwood Furnace State Park


Nestled in the mountains of northeastern Huntingdon County, historic Greenwood Furnace State Park offers a unique recreational experience. The park is on the western edge of an area of Central Pennsylvania known as the Seven Mountains. It is an area of rugged beauty, abundant wildlife, breathtaking vistas and peaceful solitude.

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 covers 423 acres, including a six-acre lake, and is surrounded by an 80,000-acre block of Rothrock State Forest. The park office is open 8 a.m. to 4 p.m. Monday through Friday year-round, and daily during the summer season.
