The centerpiece of the Fort Frederick State Park is a unique stone fort that served as Maryland’s frontier defense during the French and Indian War. Built in 1756, the Fort’s stone wall and two barracks have been restored to their 1758 appearance. Historic exhibits are in the Fort, barracks, Civilian Conservation Corps (CCC) Museum and Visitor Center. The fort barracks are open seven days a week from Memorial Day to Labor Day and on the weekends in the spring and fall, when staff and volunteers dress in period clothing and occupy the fort, demonstrating daily life in the 18th century. The 585-acre park borders the Potomac River and The Chesapeake and Ohio Canal passes through the park. The park also features a boat launch, campsites, camp store, fishing, flat water canoeing, hiking trails, a playground, a picnic area and large pavilion. Group tours are available seasonally.
