Wildlife Center/Park Office

The Wildlife Center offers opportunities to view wildlife and will house state-of-the-art exhibits and also houses the park office.


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.

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.

The ADA symbol indicates that this activity or structure is ADA accessible.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 Lowlands Trail follows the course of the First Fork through five miles of the park, passing through open fields, shrubby riparian zones and mature, towering forests. This scenic trail was originally part of the Baltimore and Ohio railroad bed. Interpretive panels along the way provide insights into the wildlife and ecology of the park.

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.
