The Sproul State Forest was named in memory of William C. Sproul, Governor of Pennsylvania from 1919 to 1923.^[1] Sproul State Forest was formed as a direct result of the depletion of the forests of Pennsylvania that took place during the mid-to-late 19th century. Conservationists like Dr. Joseph Rothrock became concerned that the forests would not regrow if they were not managed properly. Lumber and iron companies had harvested the old-growth forests for various reasons. They clear cut the forests and left behind nothing but dried tree tops and rotting stumps. The sparks of passing steam locomotives ignited wildfires that prevented the formation of second growth forests. The conservationists feared that the forest would never regrow if there was not a change in the philosophy of forest management. They called for the state to purchase land from the lumber and iron companies and the lumber and iron companies were more than willing to sell their land since that had depleted the natural resources of the forests.^[2] The changes began to take place in 1895 when Dr. Rothrock was appointed the first commissioner of the Pennsylvania Department of Forests and Waters, the forerunner of today's Pennsylvania Department of Conservation and Natural Resources. The Pennsylvania General Assembly passed a piece of legislation in 1897 that authorized the purchase of "unseated lands for forest reservations." This was the beginning of the State Forest system.^[2]

Hiking -- Two hiking trails systems designated as State Forest Trails are located within the Sproul State Forest. The Chuck Keiper Trail is a 50-mile (80 km) double looped system which includes trails in the Fish Dam Wild Area and Burns Run Wild Area. The Chuck Keiper Trail is marked with orange paint blazes.

The Donut Hole Trail is approximately 90 miles (140 km) in length and connects with the Susquehannock Trail System. The trail traverses Kettle Creek Park and terminates at Hyner Run State Park. The Donut Hole Trail is marked with orange paint blazes.

The Eagleton Mine Camp Trail, EMCT, is around a 20-mile loop that has an inter connector. The trail is marked in red. The map is found here ^[3]

There are numerous other foot trails which were originally built for fire access which provide good hiking into most parts of the Sproul State Forest. These trails are not marked or maintained. When hiking in the Sproul State forest persons should dress for the weather and use map and compass

Equestrian Use -- An Equestrian Trail located near Kettle Creek State Park is a 15-mile (24 km) loop. The Eagleton Mine Camp Trail, a multi-use trail, offers a 20-mile (32 km) loop through several historical locations in the area. Additionally with the exception of designated hiking trails and municipal watersheds, horseback riders may utilized the old woods roads and State Forest Road system. Trail maps are available by contacting the Sproul district office.

Mountain Biking -- All trails within the Sproul State Forest are open to mountain biking, with the exception of the Donut Hole Trail and the Chuck Keiper Trail. Most trails are kept clear over the summer, but some do become overgrown. It is recommended you contact the district office to find out which trails are better for riding. The Eagleton Mine Camp Trail offers excellent biking. Many sections are narrow, steep and rocky. The northern section is not as technical as the southern loop.

Cross-country Skiing -- Hiking Bear Ski Trail is located on Hyner Mountain and traverses 14 miles (23 km). The trail covers diverse terrain providing opportunities for both novice and experienced skiers.

All Terrain Vehicles -- There is one area in the Sproul State Forest open to All Terrain Vehicles use. The area is located near the Huling Branch of Two Mile Run and consists of old woods roads, old coal mining roads, and unreclaimed surface mining areas. All the rest of Sproul State Forest is closed to All Terrain Vehicle use.
