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. 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. 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 fires red glow lit the sky, probably allowing residents to walk about without lanterns. Greenwood Furnace was a village built around an inferno.

This is most likely the most educating state park in PA's system. A full schedule of educational and informative programs throughout the year, fun for all ages. A great beach and picnic area and pavillions to rent for special occasions. There are many trails to choose from, for the novice to the thru-hiker. Hikes from around the lake to spurs that connect to the Mid State Trail, (over 200 miles), or the Standing Stone Trail, (just over 70 miles). Camping is available for primitive or small campers or do as my wife and I did, Backpack to the Mid State trail, via the Fire Tower trail and camp out in Rothrock State Forest. The lake is stocked with trout throughout the year but let me give a word of advice. The feeder stream is some of the best native trout fishing in all of PA and for some reason not many people know it!
