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 nine-mile course encircling the 250-acre lake at St. Mary’s River State Park is a little known treasure. This course is also available for hiking.
