Keystone State Park This is the official page of Keystone State Park in Pennsylvania. The park was opened to the public in 1945, although its recreational use started years before.

Keystone State Park boasts a 78-acre man-made lake and a 100 year old Stone Lodge, compliments of the Keystone Coal and Coke Company that mined here years ago. Located in Derry Township, this 1,200-acre park offers a wide variety of recreational and educational opportunities year round. Visitors enjoy the picnic areas of the park, pavilions, campgrounds, cottages, yurts, and modern cabins. Keystone Lake is ideal for swimming, boating (electric motor or non-powered boats), and fishing. Many hikers enjoy the beauty of the lake as they stroll along Lakeside Trail. Nature programs, as well as historical “Coal Mining Times” programs, are available year round. Stop in the James A. Kell Visitor Center for a tour of the Old Stone Lodge and to learn about upcoming programs and events. One way to explore the park is to hit the trails, for scenic and sometimes challenging hiking, cross-country skiing and snowshoeing. Biking (on park roads and Lakeside Trail), hunting, ice fishing, sledding, and wildlife watching are some other activities you can enjoy at Keystone State Park.

It's time for your Week 5 Fall Foliage Report! 🍁🍂

The continued pattern of warm days followed by cold nights and frosty mornings is continuing to transform southern Pennsylvania’s forests into a mosaic of fall color. With minimal winds helping to extend the peak in many counties, fantastic autumn shades are now visible from the middle and southern Appalachians to the southern Alleghenies and deep into the forests of southeastern PA.

As fall foliage season winds down, this weekend may be the last great opportunity to soak in the wonderful colors across a large portion of Penn’s Woods.

It's time for your Week 4 Fall Foliage Report! 🍁🍂

Recent cold nights have sparked dramatic color changes across Pennsylvania’s forests, and now vibrant hues are bursting statewide. From the Poconos to the Allegheny Plateau, across the full sweep of the Appalachians and into the southeastern corners of the state, the autumn cheer of Penn’s Woods is on full display.

It’s shaping up to be one of the most impressive fall foliage seasons in a few years, making right now the perfect time to get outside and enjoy Pennsylvania’s breathtaking autumn scenery!
