Established in 1959 to protect the Gunpowder River and the Big and Little Gunpowder River valleys, Gunpowder Falls State Park is now one of Maryland’s largest state parks. Comprised of about 15,000 acres in Harford and Baltimore Counties, with six distinct areas, Gunpowder State Park forms a narrow corridor along the river valley, yet hosts varied topography ranging from tidal wetlands to steep and rugged slopes. Gunpowder State Park features more than 120 miles of trails; protected State Wildlands; historic sites; fishing, canoeing, kayaking, and other boating opportunities; a swimming beach, and a marina. The Hammerman Area of the park and the adjacent Dundee Creek Marina comprise about 800 acres and are located in the southeast portion of Baltimore County, near where the Gunpowder River empties into the Chesapeake Bay.

Habitat at the Hammerman Area and Dundee Creek Marina includes beach front, tidal wetlands, open fields, and deciduous/pine forests. Several short hiking trails through both wetlands and forest are available. The Hammerman Area is developed for beachfront recreation and features a swimming beach, picnic pavilions, food concessions, playgrounds, canoe/kayak and sailboat rentals, fishing, short hiking trails and two short water trails. During the winter season, the beachfront provides a great vantage point from which to scope the Gunpowder River for waterfowl. For those who wish to bird the area by boat, canoe or kayak, rentals are available at the nearby Dundee Creek Marina.  There is a lot to explore in this relatively compact area of Gunpowder Falls State Park.


There are two eBird hotspots that cover these two areas of Gunpowder Falls State Park:

The park attracts a variety of seasonal migrants (warblers and vireos) and waterfowl in the winter. This area hosts nesting Bald Eagles, present year-round, and nesting Osprey are also present during the summer months. Winter brings scaup, mergansers, Ring-necked Duck, Bufflehead, Common Goldeneye, and Ruddy Ducks to the open waters of the Gunpowder River. Along with other gulls, Bonaparte’s Gulls can be seen in late March/early April. Least, Caspian, and Forster’s Terns may be found in spring and in fall migration (August-September). A good selection of sparrows, including Dark-eyed Junco, Eastern Towhee, American Tree, Chipping, Field, Fox, White-throated, Savannah, Song, and Swamp Sparrows, can be found in late fall through early spring.


There are multiple parking areas located around the park’s central loop road. Parking is also available at Dundee Creek Marina.
