Frontier history and modern-day recreation merge at Davidsonville, once home to Arkansas’ first post office and one of the earliest courthouses. Little of Davidsonville’s existence is evident above ground; archeological excavations here are still uncovering streets, foundations, and artifacts. Fishing is a major activity here as the park borders the Black River and a fishing lake. Jon boats are available for rent. The visitor center features a replica 1820s hunter-trapper flatboat, audio tour, and a display of historic finds from archeological digs. Trails, picnic areas, and 24 campsites (11 Class AAA, eight Class A and five primitive Class D tent sites) add to the amenities.
