This park preserves the site of historic Davidsonville. Established in 1815, the town included the Arkansas Territory's first post office, courthouse and land office. Bypassed by the Southwest Trail, an overland route from St. Louis to the border of Mexico, the town faded by the 1830s. Today, archeologists are uncovering remarkable finds of streets, foundations and objects that tell a fascinating story of life on the Arkansas frontier following the Louisiana Purchase. Park exhibits and interpretive tours provide information about this important frontier town. Fishing is a major activity here today. The park borders the Black River (boat launch ramp) and a 12-acre fishing lake (no launch ramp) offering a barrier-free fishing pier, fishing boats (trolling motors only), pedal boats and canoes. Anglers may also choose from the nearby Spring and Eleven Point rivers. Facilities include 49 campsites (one Class A, 23 Class B and 25 Tent sites), picnic areas, two standard pavilions (screened), playgrounds, four hiking trails including a self-guided walking trail though the old town site, and a visitor center with exhibits and a gift shop.
