The Camp Ouachita Girl Scout Camp Historic District encompasses a campground area built by crews of the Civilian Conservation Corps in the 1930s on the northern shore of Lake Sylvia, a man-made lake in the eastern part of Ouachita National Forest. The center of the campground, including its Great Hall and administration buildings, is located at the northern tip of Lake Sylvia, with cabins, comfort facilities, and other infrastructure arrayed around the northern and western sides of the lake. It was the first Girl Scout camp in the state, and is a well-preserved example of the Rustic style of architecture for which the CCC is known.
The district was listed on the National Register of Historic Places in 1992.
