Caledon State Park is a 2579 acre state park located in King George, Virginia. As of 2010, the yearly visitation was 49,328. The property was initially owned by the Alexander brothers, founders of the city of Alexandria, and was established in 1659 as Caledon Plantation. Ownership passed, in 1974, to the Commonwealth of Virginia. A 302 acre portion of the park known as the Caledon Natural Area was designated a National Natural Landmark in 1974 for its old-growth oak-tulip poplar forest. The park also provides a habitat for bald eagles along the Potomac River. Adjacent to the park is the Chotank Creek Natural Area Preserve, a state-designated private conservation area that further protects bald eagle habitat, in addition to wetlands and other significant communities.
