Occoquan Bay National Wildlife Refuge

Occoquan Bay National Wildlife Refuge spans 644 acres of wetlands, forests, and grasslands at the confluence of the Potomac and Occoquan Rivers. The refuge provides habitat for over 200 bird species and 79 butterfly species.

The land was used by the U.S. Army's Harry Diamond Laboratories for military research from the 1960s through the 1990s. In 1998, the site was converted and established as a national wildlife refuge.

The visitor center features artwork from the Federal Junior Duck Stamp program and displays mounted raptors and songbird collections that showcase regional bird diversity. These exhibits help visitors understand the importance of birds in this part of Virginia.

Three two-mile loop trails and a wildlife drive route allow visitors to observe waterfowl, deer, red foxes, and raptors throughout the refuge. The trails suit different fitness levels and provide access to various habitats within the protected area.

The refuge maintains one of Virginia's largest stands of eastern gamma grass, reflecting its commitment to preserving native plant species. This rare grass shapes the appearance of certain areas and supports local biodiversity.
