Ozark Highlands Scenic Byway (AR-21)
Arkansas Highway 21 runs 99 miles north from I-40 at Clarksville to the Missouri state line, and its federally designated 35-mile scenic byway section — from US-64 in Clarksville to the Buffalo National River near Ponca — is the standout motorcycle stretch. The road climbs through the Boston Mountains of the Ozark National Forest with sweeping curves, open ridgeline views, and wooded hollows before descending into Boxley Valley, where AR-21 parallels the Buffalo River headwaters. A free-roaming elk herd of roughly 450 animals grazes the valley floor and occasionally crosses the highway. The byway was officially designated in 2005; the pavement is good and traffic stays light through Newton County.
