A National Natural Landmark known for its old growth forest and summer home to one of the largest concentrations of American bald eagles on the East Coast, Caledon attracts bird watchers of all ages. To protect the eagles, access to marshes and the Potomac River is limited. However, tours of the eagle habitat are offered seasonally. Forest trails are open year-round, including the Boyd's Hole Trail to the Potomac River. A visitor center with bald eagle exhibits, two picnic areas, a picnic shelter and restrooms also are available between May and September.
