The second growth forests in Promised Land State Park are made up of beech, maple, oak and hemlock trees.

Their land was part of the Province of Pennsylvania, established by King Charles II of England and under the leadership of William Penn.

[2] Many of the park facilities in use today were constructed during the Great Depression of the 1930s by the young men of the Civilian Conservation Corps.

[4] Since the forests have been allowed to regrow at Promised Land State Park it has become a center of diverse wildlife and ecosystems.

The land on which it sits has largely very rocky and shallow soil with nutrient-poor bogs and dark evergreen forests.

[2] The evergreen trees attract a variety of birds including, the red breasted nuthatch, Blackburnian warbler and northern waterthrush.

For this reason all visitors are asked to firmly secure all food products brought into the park and never to leave them out in the open overnight.

[2] In addition to the bears, Promised Land State Park is also home to variety of other large woodland creatures.

A wildlife observation deck is located on Lower Lake, from here visitors may see a variety of waterfowl species and even some bald eagles that have nested in the area within the last few years.

The feeding of Canada geese in the swimming area is discouraged due to the increased quantities of odorus fecal matter.

[2] Promised Land State Park is open year-round for recreational opportunities that include hiking, birding, fishing, swimming, boating, horseback riding, trail biking, camping, and ice skating.

The common game fish are smallmouth and largemouth bass, catfish, crappie, pickerel, muskellunge, and yellow perch.

The facilities include a sandy beach, boat launch, parking area, fresh water, picnic tables, reservable pavilions, garbage disposal containers, charcoal grills, a concession stand, a boat rental, a sand volleyball court, and restrooms with pay showers.
