Ouachita National Recreation Trail
Most of the 192-mile Ouachita National Recreation Trail is in Arkansas, but Oklahomans will tell you that the best part of the path is the 50-mile section in their state. Beginning at Talimena State Park, the trail follows the roller-coaster spine of the Ouachita Mountains, the rare range in the United States running east to west rather than north to south. Most of the miles tour the aptly named Winding Stair Mountain National Recreation Area and Upper Kiamichi River Wilderness.

Wichita Mountains National Wildlife Refuge
Eastern hardwood forests give way to the Great Plains in this refuge, where one of the largest buffalo herds in the United States roams mixed-grass prairies beside elk and the endangered black-capped vireo. A prime spot for cross-country backpacking is the Charons Garden Wilderness Unit, where you can walk among jumbled boulders in utter solitude.

Beavers Bend State Park
If you don't know what "hogbacks" and "hollers" are before you hike in Beavers Bend, you'll be well acquainted with these southern colloquialisms by journey's end. That's because hilltops and hardwood bottomlands, respectively, dominate the 30 miles of trail in this Ouachita Mountain park. Connect to trails in the adjoining Ouachita National Forest for longer journeys.
