Petit Jean State Park - Arkansas One of Arkansas' finest state park facilities, Petit Jean State Park lies in a unique area between the Ozark and Ouachita Mountain ranges in west-central Arkansas. Situated upon beautiful Petit Jean Mountain, the park encompasses 3,471 acres of rare natural beauty. In this lovely mountain setting are an abundance of unmarred woods, ravines, streams, springs, spectacular views and interesting geological formations preserved almost as French explorers found them 300 years ago.
