The Chesapeake and Ohio (C&O) Canal National Historic Park, administered by the National Park Service, is 184.5 miles long, extending from Georgetown in Washington, D.C. to Cumberland, Maryland. The canal runs parallel to the Potomac River, which forms the border between Maryland and Virginia or West Virginia. The gravel towpath alongside the canal is open to foot traffic and bicycles, and is a gateway to great birding in the Potomac River Valley. Mile markers along the towpath make it easy to keep track of your location; the markers run from Mile 0 in Georgetown to Mile 184.5 at the Terminus in Cumberland. The Recreational Guide by Milepost, available through a link at https://www.nps.gov/choh/planyourvisit/maps.htm, contains a handy list of access points and mileposts, with icons indicating the amenities available at each access point. See http://www.candocanal.org/access.html for another version of access points and parking areas.
The Frederick County portion of the C&O Canal includes access points (from south to north) at the Mouth of the Monocacy River, Noland’s Ferry, Point of Rocks, Lander and Brunswick. The riparian habitat along the Potomac River and the old C&O Canal bed provide for an abundance of species throughout the year. The path is wide, level and well-maintained, making access to birding in this area very easy.
The eBird lists for points along the Frederick portion of the C&O Canal range from 150 to 175 species or more.
The relevant eBird hotspots , from south to north, are:
- C&O Canal–Mouth of the Monocacy (Fred. Co.) – 168+ species
- C&O Canal–Nolands Ferry – 180+ species
- C&O Canal–Point of Rocks – 141+ species
- C&O Canal–Lander – 156+ species
- Brunswick Riverside Park – 118+ species
- C&O Canal–Brunswick – 94 + species
A variety of water birds are possible on the Potomac, primarily in winter and early spring. Most notable are Common Goldeneye, Common Merganser, Wood Duck, Horned Grebe, Bonaparte’s Gull, and Forster’s and Caspian Terns. Other species regularly observed in appropriate seasons include Great Blue Heron, Bald Eagle, Red-shouldered Hawk, Wild Turkey, Barred Owl, Common Raven, both Yellow-billed and Black-billed Cuckoos, all the Maryland woodpeckers except Red-headed, flycatchers, vireos, swallows, orioles, Prothonotary Warbler, Louisiana Waterthrush, and Scarlet Tanager.
Each C&O Canal access point has a level paved or gravel parking area. See maps at Trail Map link at left.
The Canal Trust has produced a mobile app, the C&O Canal Explorer, with over 600 points of interest mapped in a searchable format, allowing you to find hiking trails, campgrounds, history, trailheads, parking, and more at a glance, along the entire length of the Canal. The app is available to download for 99 cents and runs on Android and IOS devices. ◾ Wake up with the birds along the Canal: through the Canal Quarters Program, visitors may arrange for overnight stays at seven historic lockhouses along the Canal: five in Montgomery County, one in Frederick County, and one in Washington County. See https://www.canaltrust.org/programs/canal-quarters/canal-quarters-lockhouses-overview/ for details. ◾ Sections of the Canal are included in the Lower C&O Canal Important Bird Area (IBA), as designated by the National Audubon Society. ◾ Two restored, historic aqueducts are along this stretch of the C&O Canal: Monocacy Aqueduct at the Mouth of the Monocacy and the Catoctin Creek Aqueduct accessible from Lander. ◾ The Brunswick Visitor Center for the C&O National Historic Park is at 40 West Potomac Street, Brunswick, MD 21716 [(301) 834-7100].
