Ricketts Glen State Park is a Pennsylvania state park on 13,050 acres (5,280 ha) in Columbia, Luzerne, and Sullivan counties in Pennsylvania in the United States. Ricketts Glen is a National Natural Landmark known for its old-growth forest and 24 named waterfalls along Kitchen Creek, which flows down the Allegheny Front escarpment from the Allegheny Plateau to the Ridge-and-Valley Appalachians. The park is near the borough of Benton on Pennsylvania Route 118 and Pennsylvania Route 487, and is in five townships: Sugarloaf in Columbia County, Fairmount and Ross in Luzerne County, and Colley and Davidson in Sullivan County.
The park offers hiking, ten cabins, camping (one of the two camping areas is on a peninsula in the lake), horseback riding, and hunting. Lake Jean is used for swimming, fishing, canoeing and kayaking. In winter there is cross-country skiing, ice fishing on the lake, and ice climbing on the frozen falls. The Glens Natural Area has eight named waterfalls in Glen Leigh and ten in Ganoga Glen, these come together at Waters Meet; downstream in Ricketts Glen there are four to six named waterfalls. The park has four rock formations from the Devonian and Carboniferous periods, and is home to a wide variety of plants and animals. It was named an Important Bird Area by the Pennsylvania Audubon Society and is an Important Mammal Area too. Ricketts Glen State Park was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of State Parks as one of "Twenty Must-See Pennsylvania State Parks".
