Situated at the northern end of the St. Mary's River watershed, 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. This area has been improved by a modern comfort station, picnic tables, playground, boat launch ramps and a large gravel parking lot. Pets are allowed in the state park. Site 1 St. Mary's River State Park offers an accessible bathroom and seasonal boat launching facility. ​​Site 2 covers approximately 2,200 acres and is primarily undeveloped. It is a wildlands area and a managed hunting area. Parking is permitted in designated areas only. 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. The day use service charge is $3/vehicle year-round. Out-of-state residents add $2.
