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.
Attention: Patuxent River State Park has many unmarked “social” trails that have been created by trail users, wildlife, and volunteers over the years. These trails are not maintained by park staff and should be used at your own risk. Plans are underway to grow an 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.
