In the early years, there were some wonderful Marlborough Hunt Club fixtures held mostly at lovely old estates in Prince George's County, such as "Beechwood," “Keokuk,” “His Lordship’s Kindness,” “Oakland,” "Montpelier," and “Blythewood,” which extended down along the Patuxent River.

Today, the Marlborough hunt country covers about 25 miles square and takes in parts of Prince George’s, Anne Arundel, Calvert, and Charles counties.  It is bounded on the north approximately by U.S. Highway 50; on the east by the Chesapeake Bay; on the west by the District of Columbia and the Potomac River; and on the south by a line drawn approximately from the town of Indian Head in Charles county, easterly to the town of Dares Beach in Calvert county.

Marlborough’s country consists of rolling fields and pastures and woodland coverts with a number of trappy crossings. Fences are mostly coops with some board, natural, and post and rail fences.

The Kennels and turn-of-the-century Clubhouse are situated on Hunt Club property along the western shore of the Patuxent River near Hill’s Bridge, east of Upper Marlboro in Prince George’s County.
