Patuxent River State 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. (Source)
