Ouachita National Forest, spanning 1.8 million acres across Oklahoma and Arkansas, is the oldest and largest National Forest in the South. It offers a diverse landscape of rolling hills, lush valleys, and crystal-clear streams. Towering pine and hardwood trees provide a haven for wildlife, including black bears and bald eagles. For thousands of years the Caddo, Quapaw, Osage and Choctaw Nations inhabited this region. Today it is a haven for hikers, with scenic trails like the Ouachita National Recreation Trail. Visitors can also camp, fish, and enjoy scenic drives.
