Sinnemahoning State Park
Sinnemahoning State Park, located near the center of the Pennsylvania Wilds’ scenic steep valleys region, encompasses 1,910 acres of beautiful scenery and outstanding wildlife habitat. Situated in Cameron and Potter counties, the park is nestled between the green-shouldered ridges of Pennsylvania’s Elk and Susquehannock State Forests. The park is long and narrow and includes lands on both sides of First Fork Sinnemahoning Creek, a major tributary to the Sinnemahoning Creek. At the southern end of the park, a 145-acre reservoir created by the George B. Stevenson dam provides excellent fishing and water recreation opportunities. The abundance of wildlife within the park provides visitors with opportunities to view bald eagles, coyotes, elk and bobcats. In addition, the park’s geographic location is excellent for visitors to explore the other treasures of the PA Wilds region.
Picnicking: The park contains two main picnic areas. The Eagle Watch Picnic Ground at the George B. Stevenson reservoir is located in an open grassy area, and includes picnic tables and charcoal grills. In addition, a pavilion with an adjoining checkers/chess table and grill is located at the Eagle Watch Area directly above the boat launch.
The 40 Maples Day Use Area includes two ADA accessible pavilions, along with numerous individual picnic tables scattered throughout the area. It also contains a volleyball net, horseshoe pits and a basketball half-court. Electricity is not available in this area
Pavilions can be reserved up to 11 months in advance and must be reserved at least two days in advance. Unreserved pavilions are free on a first-come, first-served basis

Fish Habitat Improvement: For several years, Sinnemahoning State Park has partnered with the Pennsylvania Fish and Boat Commission’s Cooperative Habitat Improvement Program (CHIP) to place fish and turtle habitat structures in the lake and ponds throughout the park. This program places habitat structures, primarily made of wood or rocks, in lakes or impoundments in the Commonwealth. The habitat structures mimic the aquatic environment in a natural lake and aid in the survival and reproduction of aquatic species.
Hunting and Firearms: About 1400 acres of the park are open to hunting, trapping and the training of dogs during the established seasons. Common game species are deer, grouse, squirrel, bear, turkey and waterfowl.
Hunting woodchucks, also known as groundhogs, is prohibited. Dog training is only permitted from the day following Labor Day through March 31 in designated hunting areas. The Department of Conservation and Natural Resources and the Pennsylvania Game Commission rules and regulations apply. Contact the park office for ADA accessible hunting information.
Use extreme caution with firearms at all times. Other visitors use the park during hunting seasons. Firearms and archery equipment used for hunting may be uncased and ready for use only in authorized hunting areas during hunting seasons. In areas not open to hunting or during non-hunting seasons, firearms and archery equipment shall be kept in the owner's car, trailer or leased campsite. Exceptions include: law enforcement officers and individuals with a valid Pennsylvania License to Carry Firearms are authorized to carry a firearm concealed on their person while they are within a state park.
Complete information on hunting rules and regulations in Pennsylvania is available from the Pennsylvania Game Commission Web site.
Hiking: 5 miles of trails
An ADA accessible wildlife viewing platform is located at the northern trailhead of the Lowlands Trail. This area is ideal habitat for deer, elk, woodcock, migratory songbirds and monarch butterflies. The trail from the wildlife viewing platform to the 40 Maples Day Use Area is ADA accessible.
A spur of the trail near the 40 Maples Day Use Area leads to a secluded viewing blind that overlooks an abandoned beaver pond. Quiet visitors may be able to see great blue herons wading in the pond or painted turtles basking on partially submerged logs. Osprey, green herons, belted kingfishers, bobcats and whitetail deer also frequent the area.
For a more primitive hiking experience, visitors can hike the Red Spruce Trail from the campground to the 40 Maples Day Use Area. This trail skirts an exceptional wetland area and passes under the dense canopy of mature mixed hardwood forest. This one-mile trail is marked with yellow blazes. Areas of rocks and roots make this trail surface more challenging than the Lowlands Trail.
