Fort Frederick State Park / Big Pool

(301) 842-2155

Fort Frederick State Park, with 585 acres, is also known among birders as Big Pool on account of one of its prominent features. The park includes open mowed areas, the Potomac River, a portion of the C&O Canal, a small beaver pond, and Big Pool itself, a natural depression that was filled with water when the C&O Canal was created. Fort Frederick offers many different types of bird habitat and is the #1 eBird hotspot in Washington County in terms of number of species reported.

Fort Frederick also has significant historical interest, the fort having played a role in the French and Indian War (1754-1763) and in the American Revolution. During the summer months, there are tours of the restored fort, military reenactments, and other special events. Nearby, an abandoned railroad bed has been converted to a paved hiker-biker path, part of the Rails to Trails system. Fishing and boating are permitted on Big Pool as well as on the Potomac River.  A boat ramp (no gasoline motors) is located on Big Pool. The park features a visitor center, campsites, a camp store, a hiking trail, interpretive and educational programs, picnicking, a playground, and a shelter.

Also nearby is the Woodmont Natural Resource Management Area (NRMA).  This former rod and gun club , with overt 3,400 acres of land, is managed through a cooperative agreement between the Maryland Department of Natural Resources (DNR) and the Woodmont Chapter of the Izaak Walton League of America. The property is open to hiking and birding, but a portion of the property is off-limits to public use for part of the year. The limited use section is shown on the Woodmont NRMA trail map at The habitat diversity at Woodmont provides birders with a mix of mature and young growth forests and fields and includes frontage on the Potomac River. To reach Woodmont NRMA from I-68, take exit 77. Turn left onto US Route 40, then turn right onto Woodmont Road. Follow Woodmont Road approximately 6 miles. Signs mark the entrance.​​​

Louisiana Waterthrush, Cerulean Warbler, Kentucky Warbler, and American Redstart can be found here. Many Eastern Bluebirds can be seen in the open areas of the park. Big Pool and the Potomac River offer a good place to observe migrating and overwintering ducks , including Common Merganser, Wood Duck, and Lesser Scaup.

Wheelchair Access:

Paved parking areas have handicapped spaces. Some restrooms are handicapped-accessible – see the trail map link at left and look for the blue restroom icons. Foot-trails are not wheelchair-accessible, but some birding is possible from the car using the paved road system within the park, including the road to and within the campground. The C&O Canal Towpath runs past the Beaver Pond and Big Pool and has a crushed gravel surface that may accommodate wheelchairs, but may be bumpy or have puddles. There is a short paved walkway around the Visitor Center and to the fort.
