Sproul State Forest was the first Pennsylvania State Forest. Located in northern Centre county and western Clinton county, this state forest encompasses over 300,000 acres of land. The west branch of the Susquehanna River bisects the state forest. There are a number of hiking trails found in Sproul State Forest, including two long distance hiking trails. The Chuck Keiper Trail and Donut Hole Trail are great trails for overnight backpacking. If dayhiking is more your speed, you’ll find plenty of opportunities around Kettle Creek State Park or Hyner Run State Park. To see what Sproul State Forest has to offer in regards to hiking, make sure to participate in “Prowl the Sproul”, hosted every summer by DCNR and the Keystone Trails Association.
