 Oil Creek State Park was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of Parks as one of "25 Must-See Pennsylvania State Parks".The history of Oil Creek State Park is tied to the rise and fall of the oil industry in northwestern Pennsylvania.What is now a wild second growth forest with several cold water fishery creeks flowing through it, was once the site of the vast oil industry that changed the landscape and water quality of the Oil Creek Valley.
