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.

In the late 1920s, entrepreneur Henry Woodhouse reassembled the parcels, purchasing 1,500 acres (610 ha) from 10 landowners.

He dreamed of transforming Hybla Valley's dairy farms into the George Washington Air Junction, which he claimed would be the largest airport in the world.

In 1992 the Fairfax County Park Authority, with financial assistance from Ducks Unlimited, purchased an additional 165 acres (67 ha) of adjacent wetland and upland.

Biodiversity in what is now referred to as the Central Wetland rapidly increased and a boardwalk was opened in 1982 to allow visitors the opportunity to closely observe the largest habitat of its kind in the region.

The staffed visitor center offers many exhibits on the park's human and natural history as well as educational programs for all ages.

In addition to its dedication to the protection of park resources, the organization also helps provides funding for programs, internships, and equipment.

Various naturalist talks, school education programs, self-guided tours and even artistic performances are part of the park.

The park has undertaken initiatives, such as boot cleaning sites at trailheads to limit seeds being spread,[7] to attempt to combat it.
