The 1,125-acre Caledonia State Park is in Adams and Franklin counties, midway between Chambersburg and Gettysburg along the Lincoln Highway, US 30.

The park is nestled within South Mountain, the northern terminus of the well-known Blue Ridge Mountain of Maryland and Virginia. Within South Mountain there are four state parks and 84,000 acres of state forest land waiting to be explored and enjoyed. The soils on either side of South Mountain are ideal for fruit production, proven by the abundance of orchards in the surrounding area.

Modern campground host site amenities include 30-amp electric service. A two-week minimum stay is required. Hosts are required to assist park personnel for 40 hours per week. Contact the park office for additional information and availability.
