## Overview Devil’s Den State Park is a 2,200-acre state park located in Washington County, Arkansas, nestled in the Lee Creek Valley of the Boston Mountains, which form the southwestern edge of the Ozarks[1][4]. Established on October 13, 1933, it stands as one of the best-preserved Civilian Conservation Corps (CCC) park developments in the United States, recognized for its rustic-style wood and stone structures that seamlessly blend with the surrounding natural beauty[1][2]. The park’s amenities—ranging from cabins and campgrounds to a café and swimming pool—are complemented by over 60 miles of trails for hiking, mountain biking, and horseback riding, as well as unique geological features such as caves, crevices, and bluff overlooks[1][3]. ## History and Development Devil’s Den’s origins trace back to the Great Depression, when the federal government acquired the land from families unable to pay property taxes[1]. The CCC, established by President Franklin D. Roosevelt, began developing the park immediately, constructing roads, trails, a stone dam on Lee Creek (forming the 8-acre Lake Devil), and the park’s iconic cabins and facilities, many of which remain in use today[1][2]. The park’s development continued until the CCC disbanded in 1942, leaving a legacy of craftsmanship and conservation that endures[1]. ## Key Achievements and Notable Features Devil’s Den is renowned for housing the largest sandstone crevice cave area in the country, though most caves are now gated to protect bat populations from White Nose Syndrome[1][3]. The park’s trails, including the challenging 15-mile Butterfield Trail, attract outdoor enthusiasts year-round[3][5]. It is also a designated Natural Area by the Arkansas Natural Heritage Commission, underscoring its ecological significance[1]. The park’s dam, completed in 1937
