This 85-acre state park is dominated by Mt. Pisgah, an 885-foot high ridge separating Kreutz Creek Valley and East Prospect Valley. The overlook offers a spectacular view of the Susquehanna River Valley. The park landscape consists of mowed grass fields on the northern and eastern park slopes, pine plantations in the southern area and mature woods on the western section of the park.

Samuel S. Lewis State Park was named to honor the Secretary of the Pennsylvania Department of Forest and Waters from 1951-1954. Samuel S. Lewis donated 35 acres of his farm to the Commonwealth in 1954. Lewis convinced Walter Stine to sell his arboretum to the Commonwealth for a reasonable price. The Commonwealth then purchased an additional 35 acres of the adjacent Almoney Farm to complete the initial park tract. The park opened to the public on July 4, 1954. The Department of Conservation and Natural Resources purchased an additional 14 acres of land in 1999.

There are no entrance fees or day use fees for any state park in Pennsylvania.
