A forested Ouachita Mountain wilderness of sandstone ridges, shady streams, and long-distance trails in central Arkansas.
Flatside Wilderness
Flatside Wilderness is a 9,507-acre federally protected wilderness area in central Arkansas, located within the eastern Ouachita National Forest. It spans southern Perry County and northwestern Saline County, with most of its acreage falling in Saline County. The wilderness is recognized for its rugged sandstone ridges, broad forested summits, clear mountain streams, and a notable segment of the Ouachita National Recreation Trail.
The area lies within the Ouachita Mountains, a regionally distinct range characterized by east-west oriented ridges and valleys rather than the more familiar north-south Appalachian structure. Several named summits and pinnacles rise above 1,000 feet, with White Oak Mountain forming the highest ridge in the wilderness. Flatside Wilderness is one of six designated wilderness areas in the Ouachita National Forest and its easternmost, making it a key component of Arkansas's wilderness system.
Ecologically and scenically, the wilderness offers a combination of high-relief forested terrain, perennial streams, and panoramic overlooks. It is valued as a relatively undisturbed backcountry experience within driving distance of central Arkansas, and it plays a meaningful role in protecting representative Ouachita forest ecosystems.
