Smallwood State Park

2750 Sweden Point Road, Marbury, MD 20658
(301) 743-7613

The 628-acre Smallwood State Park, managed by the Maryland Department of Natural Resources, is located on the Mattawoman Creek in northern Charles County. (Do not confuse Smallwood State Park with Fort Smallwood Park, a county park in Anne Arundel County.) Smallwood State Park offers a trail system that leads through deciduous woods and past stands of pine. There are both tidal and non-tidal wetlands within the park, and there is an excellent view of Mattawoman Creek, quite broad at this point, from a number of vantage points. A field near the park entrance is managed for pollinators, and there are also scattered lawn areas. The varied habitats within the park provide for a good diversity of bird species, and the road and trail system enables all the park areas to be thoroughly explored.

Smallwood State Park takes its name from General William Smallwood, a native of Charles County whose family property is now the state park. He was the highest ranked Marylander who served in the American Revolutionary War. He later became the State’s fourth governor and oversaw Maryland’s ratification of the federal Constitution. His home, known as Smallwood’s Retreat, was built around 1760 as the heart of his tobacco plantation. The house has been restored and is open to visitors seasonally.

The trail map for Smallwood State Park (link at left) is geolocator-enabled, which means that you can load it into a GPS app on your Smartphone (such as the free Avenza app), and you will be able to see where you are within the park, and track your movements along the trails, using the map within the app.

Smallwood State Park has two trails that are especially good for birding. The General’s Walk Trail is a loop that runs between headquarters, Smallwood’s Retreat (the historic home), and the campground. This trail features a variety of ecosystems, including hardwood forests and tidal wetlands. This loop is nearly two miles long and includes several exit points if you wish to shorten your hike. While some portions of this trail are easy, the entire hike should be considered moderate due to several uphill and downhill portions.

The Birdwatchers/Bluebird Trail is a short trail that can be done as a loop from the Mattawoman Creek Art Center, located on Mattawoman Creek within the park. This loop is about 3/4 of a mile, and is a flat easy hike. The trail leads through a wooded area and skirts the edge of a large meadow.

In addition to walking the trails, be sure to check the Mattawoman Creek, viewable from the Sweden Point Marina area, the fishing pier, and near the Arts Center. There is also a tidal marsh near the fishing pier, and a pedestrian bridge over the mouth of the marsh makes for good viewing.


Over 170 species have been reported at the  eBird hotspot for Smallwood State Park. Waterfowl are a specialty of the park in winter, with 19 species reported. Canada Goose, Mallard, and Wood Duck breed here and may be found year-round. Pied-billed and Horned Grebes may be present in winter and spring, and Red-necked Grebes join them in spring. The usual three gulls (Ring-billed, Herring, and Great Black-backed) are present fall through spring, joined in late summer and early fall by Laughing Gulls. Terns include Caspian, Common, Forster’s and Royal. Ospreys (spring through early fall) and Bald Eagles (year-round) are abundant.

All of the locally breeding woodpeckers are present year-round, including Red-headed, and Yellow-bellied Sapsuckers join them in winter. This is a good spot to look for migrant thrushes in spring. Wood Thrush are present in spring and summer, and Hermit in winter. Other songbirds found seasonally include the usual swallows, flycatchers, vireos, sparrows, and warblers (19 species reported).

Wheelchair Access:

For those who are mobility-impaired, good birding is possible from the car, either on the road system within the park or at the parking areas and marina.

Pet Policy:

Pets are permitted and must bed kept on a leash. You must pick up after you pet and take the waste with you when you leave: Maryland State Parks are trash-free.

Special Designations:

Smallwood State Park is a part of the Chesapeake Bay Gateways Network of the National Park Service.

Special Features:

The Sweden Point Discovery Center in the park provides indoor and outdoor activities for children. ◾ Part of the Potomac Heritage National Scenic Trail goes through the park. ◾ The Mattawoman Creek Water Trail uses the marina in the park as one of its access points. The Water Trail goes into prime wetland habitat in the Mattawoman Natural Environmental Area. The Water Trail is depicted on the interactive map of the Maryland Public Water Access Atlas. ◾ The historic home, Smallwood’s Retreat, is open to visitors seasonally. ◾ The park has a full-service marina, boat launching ramps, fishing pier, picnic area, camping area, pavilions, and playground. A concession store at the marina is open seasonally. ◾ The Mattawoman Creek Art Center is located in the park. ◾ The Friends of Smallwood State Park help to support the park with local fund-raising and volunteer activities. ◾ There is no chapter of the Maryland Ornithological Society in Charles County, but many birders participate in MOS through the Anne Arundel Bird Club or the Patuxent Bird Club; both of these MOS chapters offer field trips and meetings with informative programs, all free and open to the public. ◾ In addition, the Southern MD Audubon Society serves birders in Charles, Calvert, St. Mary’s, and Prince George’s Counties.


Osprey Cam:  Thanks to a generous donation from the Southern Maryland Audubon Society, MD DNR is providing a live-stream feed of an Osprey nest at the park. Osprey are generally most active on this nest site between mid March and early July, however, it is not uncommon to have other birds such as Bald Eagles stop to rest on the platform at other times of the year.
