Swatara State Park is a 3,515-acre (1,422 ha) Pennsylvania state park in Bethel, Swatara and Union Townships, Lebanon and Pine Grove Township, Schuylkill Counties in Pennsylvania in the United States. 8 miles (13 km) of Swatara Creek lie within the park's boundaries, which are roughly formed by Pennsylvania Route 443 to the north and Interstate 81 to the south. The park is in a valley in the Ridge and valley region of Pennsylvania between Second Mountain (north) and Blue Mountain (south).
Swatara State Park is a fairly new park for the Commonwealth of Pennsylvania. It was opened in 1987 and is still largely undeveloped. The Pennsylvania Department of Conservation and Natural Resources is working on plans to further develop the lands of Swatara State Park. The original plans called for the building of a dam and reservoir for recreational fishing and boating as well as to provide drinking water for the City of Lebanon. The PADCNR is also exploring plans for developing the park without the recreational lake/reservoir.Forests are overtaking the land formerly used by farmers, miners, canalmen and railroadmen. Woodlands are plentiful at Swatara State Park. Visitors can observe the slow process in which nature reclaims the land previously used by man. Fossil hunters can find ancient marine fossils at a site along Old State Route 443.
