The History of Keystone State Park

The Keystone Coal and Coke Company purchased the land in 1909 in order to build a lake to use as a water source. Coke is needed to make steel. In coke production, coal is burned and then must be extinguished quickly, necessitating large amounts of water. The company built a structure there for executives to use as a hunting lodge. By 1945, the local coal veins had run dry. The land, lake, and lodge was then purchased by the Pennsylvania Bureau of State Parks, who named it Keystone State Park, after the company from which it had come.

There are five hiking trails snaking throughout Keystone State Park. Only the Lakeside trail is intended for bicycles. The other four trails are intended for foot traffic only, whether it be hiking, cross-country skiing, or snowshoeing. Out of the five trails, four are listed as easy- a rare find in mountainous western Pennsylvania. Avid walkers can view a plethora of wildlife and flora scattered throughout the park in all seasons. As hunting is indeed permitted in the correct time-frames, be sure to wear a blaze orange vest if you plan to sightsee during hunting seasons.

The Water

The man-made lake sees visitors in all seasons and for a variety of activities. For the fisherman, both warm and cold-water fish varieties are found, including: northern pike, black crappie, largemouth bass, yellow perch, and carp. Trout are stocked at regular intervals throughout the year. In winter, ice fishing is permitted. However, it is important to note that the ice thickness is not monitored and it is the guest’s responsibility to ensure their own safety. There is an ADA-accessible fishing site located near the spillway.

For pleasure boaters, Keystone Lake is a serene body of water to navigate. Only hand-powered vessels or those outfitted with electrical engines are permitted on the lake. Gas and diesel engines are strictly prohibited from this delicate ecosystem. All boats must of course bear the proper licensing stickers and carry sufficient life vests for the passengers aboard.

For swimmers and sunbathers, a sand beach is open from late May until the middle of September with daily hours of eight in the morning until seven in the evening. No lifeguards are stationed. No food, beverages, or pets are permitted on the beach to ensure cleanliness and safety for all guests.
