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.
Boyd's Hole Trail is a 3.49 kilometer trail in Caledon State Park featuring a gentle elevation gain of 30.42 meters through pristine old growth forest. This protected natural area offers seasonal bald eagle viewing opportunities and leads to the scenic Potomac River, with access to interpretive exhibits at the visitor center during peak season.
