Great Dismal Swamp National Wildlife Refuge


Comprised of nearly 113,000 acres of forested wetlands, canals, ponds, lakes, sphagnum bogs, evergreen shrubs, and marshy borders, the Great Dismal Swamp National Wildlife Refuge is the largest site on the Coastal section of the Virginia Birding and Wildlife Trail. The refuge may be explored via 40 miles of nearly level trails and roads, many of which parallel drainage ditches surveyed by George Washington during the mid-1700s. Multiple entrances are available. It’s recommended to obtain a map from the Refuge website or visitor center.

Three-mile wide Lake Drummond, located in the heart of the Swamp, is one of only two natural lakes in Virginia. This tannin-stained, cypress-lined, isolated lake may be visited from the east by small paddled craft, or from the west by road and hiking/ biking trails. A self-guided driving tour, the “Lake Drummond Wildlife Drive,” can be accessed from the Railroad Ditch trailhead. The tour is a 6-mile trail on a one-way gravel road, and features three boardwalks to stop at along the way.

The Great Dismal Swamp is a naturalist’s dream. Over 200 species of birds, including 35 kinds of warblers, attract birders, most of whom visit the Swamp during spring migration in mid-April to mid-May. Even after the frenzy of spring migration subsides, wildlife watching in the Swamp can still be very rewarding. The Swamp remains alive with the summer songs of breeding prothonotary, prairie, Swainson’s, pine, black-and-white, yellow-throated, yellow, hooded, Kentucky, and black-throated green warblers, northern parula, and dozens of other birds.

While searching for the refuge’s many birds, even the most casual observer will encounter some of the Refuge’s 87 species of reptiles and amphibians. Small mammals are abundant, and large species such as black bear, bobcat, and river otter are encountered with unusual frequency. In fact, the Refuge may currently provide the best opportunity to see black bears in the entire state. The Swamp is an excellent locale for studying butterflies of the southeastern United States, including cane-specialists such as lace-winged roadside-skipper and creole pearlyeye.

Note: Mosquitoes are also present in large numbers, so bug spray is highly recommended.
