Visit St. Mary's County Maryland

Where the Potomac & the Chesapeake meet

St. Mary’s River State Park

Situated at the north end of the St. Mary's River watershed in the center of the county, the park consists of approximately 2,000 acres of land with a 250-acre fishing lake. The relatively flat landscape of St. Mary's County is not usually thought of as mountain biking terrain; however, the 7.5-mile course encircling the lake at St. Mary's River State Park is a little-known treasure. This course is also available for hiking. Park open daily dawn to dusk April - October. Call for extended hours and dates.

St. Mary's River State Park is divided into two areas, Site 1 and Site 2. Site 1 included St. Mary's Lake and has an entrance and parking off Camp Cosoma Road. Site 2 is a wildlands and managed hunting area.

Hunting information: 2,200 acres of public hunting lands. Firearm and bow and arrow hunting are allowed in-season. Reservations required. Call 301-872-5688 or visit the DNR website for more information. For reservations call 301-743-5161.

Birding

Take Rt. 4 south from the intersection of Rts. 4 and 235, then turn left onto Indian Bridge Rd. Drive east on Indian Bridge Road past the power lines, then turn left at the brown and white "hunter" sign. Park in the small parking area at the end of the gravel drive. Follow the gravel drive from the parking area into the woodlands area. St. Mary's Lake is accessible from Route 5 via Camp Cosoma Road near Callaway, and has a boat launch for canoes and kayaks. Both areas are good for forest birds, and freshwater shoreline birds, via foot trails and the canoe/kayak launch. This area makes for pleasant birding, and you often get Red-headed Woodpecker, Tree Swallow, Hooded and Kentucky Warblers and other forest interior dwelling species such as thrushes during migration.
