About the Park


Located in Howard and Montgomery counties, along the upper 12 miles of the Patuxent River, the park is comprised of 6,700 acres of natural areas and farmlands. A portion of the park is a state wildlands area.

Recreational use is primarily hunting, fishing, hiking and horseback riding. The park includes a catch and release trout stream, designated hunting areas and unmarked hiking and equestrian trails. Note: The Maryland Park Service does not rent horses, and only provides the trails as a means of recreation.

The park is located Howard/Montgomery County line between Maryland Routes 27 and 97. Paths lead from parking areas at Long Corner, Mullinix Mill, Route 94, Hipsley Mill, Howard Chapel and Route 97 road crossings over the river.

Patuxent River State Park has mapped, blazed and maintained public trails in two areas: three miles of trails in the Southern Area between Route 97/Georgia Avenue and Howard Chapel Road, and six miles of trails in the Central Area between Annapolis Rock Road and Mullinix Mill Road. Detailed trail maps for the Southern Area and the Central Area are available in the links above.

​Other areas of Patuxent River State Park have many unmarked “social” trails that have been created by hikers, hunters, and equestrians over the years. These paths are not maintained by park staff and should be used at your own risk. Plans are underway to continue to grow the official trail system that will replace the network of social trails. If venturing along social trails, bring a cell phone and note our Duty Ranger number (443-962-0216). GPS technology is recommended when utilizing social trails.

​Large issues or hazards within the park can be communicated via text or call to the Duty Ranger.
