Occoquan Bay is a coastal bay on the Potomac River in Virginia, forming part of the Potomac River Wildlife Refuge Complex. The Occoquan Bay National Wildlife Refuge protects diverse upland and wetland habitats, supporting over 200 species of birds, 79 species of butterflies, and 77 species of dragonflies and damselflies. A primary access point for paddlers is Occoquan Regional Park in Woodbridge, Virginia, which offers a car-top boat launch suitable for kayaks and canoes. This launch point features amenities including paid and free parking, year-round and seasonal bathrooms, drinking water, and picnic facilities. The park provides picnicking and hiking trails overlooking the Potomac River and Occoquan Bay. Paddlers should be aware of restricted areas within the bay, as indicated on the Occoquan Water Trail map. The area is also used for paddling events, such as the Occoquan Bay Race held at Occoquan Harbour Marina. As a tidal saltwater bay, paddlers must plan for tidal currents and wind exposure on the open Potomac River. The refuge has a visitor information center open Thursday through Saturday, and management focuses on protecting habitat for migratory birds and endangered species.
