Situated at the northern end of the St. Mary's River Kayaking at St. Mary's River lakewatershed, the park shows a wide range of habitats, from wooded acres and fields to swamps and small streams. With such a diversity, you can also find many different types of plant and animal species. Check out a map of the area.
St. Mary's River State Park is separated into two areas, Sites 1 and 2. The Site 1 area holds the 250 acre St. Mary's Lake. Located along Maryland Route 5, between Leonardtown and Great Mills, at the end of Camp Cosoma Road, the area has become a popular freshwater fishing spot. Several species of fish are common to the lake including largemouth bass, chain pickerel, crappie, bluegill and sunfish. The lake has been designated a trophy bass lake and as such, special fishing regulations may be in effect. Fishermen should check bulletin boards or contact park personnel for details. Please note that electric motors only are allowed on the lake.
A 7.5 mile trail circles the lake, allowing the area to be fished from shore or by boat (electric motor only). The trail is regularly used for hiking, biking and horseback riding. The Maryland Park Service does not rent horses, and only provides the trails as a means of recreation. There is waterfowl hunting at designated sites only (accessible by boat). Permit (free) and reservation are required. You can make reservations by calling 301-743-5161 between 8 a.m. and 12 p.m. The Site 1 area has been improved by a modern comfort station, picnic tables, playground, boat launch ramps and a large, gravel parking lot. Picnicking is permitted but tables are limited. Pets are allowed in the state park.
Site 2 covers approximately 2,200 acres and is primarily undeveloped. It is a wildlands area and a managed hunting area. Small game such as rabbit and squirrel, as well as white-tailed deer are found here. Hunting with a firearm is permitted. You may hunt with bow and arrow during the regular archery season for deer. For specific regulations and seasons, check the Guide to Hunting and Trapping in Maryland. Parking is permitted in designated areas only.
