Keystone State Park (Pennsylvania)

Keystone State Park is a 1200 acre Pennsylvania state park in Derry Township, Westmoreland County, Pennsylvania in the United States. Located off U.S. Route 22 near New Alexandria, the park opened in 1945. Its main attraction is the man-made 78 acre Keystone Lake. The park also has extensive picnic areas and several miles of hiking trails.

History
Keystone Coal and Coke Company constructed Keystone Lake in the early 1900s for use in washing coal extracted from a nearby coal mine known as Salem #1 and quenching its coke ovens. A second mine, Salem #2, was in operation by the 1910s. Both mines had ceased operations by 1945. Abandoned mine tunnels lie beneath Hillside Campground and the cabin area. A mine entrance, now sealed, is located east of Pavilion #2 and north of the cabin entrance road.

Recreation
Keystone State Park is open to camping and also has several cabins that are available to rent year round.

Keystone State Park has two campgrounds. Lakeside campground is on the shores of Keystone Lake. It has 40 campsites for tents or campers. Hillside campground is in a more remote part of the park. It has 60 campsites, also for tents or campers. Each campground has some sites with an electric hook-up, a modern bathhouse and a sanitary dump station.
