Notable for its large size and unique construction, the stone wall and two barracks of this circa 1756 frontier fort have been restored to their original appearance. The site of Maryland's frontier defense during the French and Indian War (1754-1763), park lands adjoin the Potomac River and the historic Chesapeake and Ohio Canal passes through park acreage as well.
The fort's past is interpreted through living history programs, costumed narration, and exhibits throughout the fort building, barracks, and Visitor Center; tours available by request. The park annually sponsors military reenactments and other special events; daily living history programming is offered Memorial Day through Labor Day.
Recreation at the site includes a boat launch and boat rentals, hiking trails, cross country skiing, camp fire programs, campsites, camp store with food and beverage, fishing, flat water canoeing, picnicking and shelters, and playground equipment; boats can be used on Big Pool only.
