Huntley Meadows Park, the largest park operated by the Fairfax County Park Authority (1,452 acres (588 ha)), is located in the Hybla Valley area of Fairfax County, Virginia, south of the city of Alexandria. The park features a visitor center, a beaver-created wetland with boardwalk, wildlife observation platforms, and an interpretative trail system. The park is home to abundant wildlife and is known for attracting many birds, amphibians, and plants that are considered less common in the region. Secondary-growth forest, sprinkled with several small, native-grass and wildflower meadows surround much of the wetland habitat.
