Little Sahara State Park in Waynoka in Woodward County, northwest Oklahoma, covers more than 1,600 acres of sand dunes on the edge of the Great Plains — a surprise in the Oklahoma landscape where the flat agricultural plains of Woodward County transition into a wind-deposited dune system that reaches 75 feet in height and provides the closest thing to genuine dune OHV riding available to Oklahoma, Texas Panhandle, and southern Kansas riders without a multi-state haul. The park's position in the Great Plains means the surrounding context is flat, open ranch country: the dunes appear at the crest of a low ridge and reveal themselves gradually as the flat horizon transforms into a dune field. Oklahoma's climate at this latitude gives Little Sahara a year-round operational window with relatively mild winters and hot summers — the spring and fall seasons (March through May, September through November) offer optimal temperatures for riding. ATVs, dirt bikes, and dune buggies are the primary permitted vehicle classes on the designated dune area. The park maintains a developed campground with RV hookups and tent sites, a concession stand, a vehicle wash area, and ATV rentals for visitors who arrive without machines — a full-amenity configuration that makes Little Sahara a practical day-destination for the Oklahoma City, Wichita, and Amarillo markets. Day-use fees and camping fees apply through the Oklahoma State Parks system. Woodward, 35 miles southeast, provides full services for multi-day stays.

The Ouachita National Forest ATV Trail system in the Choctaw Ranger District occupies the Kiamichi Mountains of southeastern Oklahoma near Big Cedar — the wildest and most topographically rugged corner of Oklahoma, where the Ouachita Range pushes north into the state from Arkansas in a series of parallel sandstone ridges and shale valleys that are unlike anything in the flat-plains interior of the state. The system runs within the Winding Stair Mountain National Recreation Area corridor, which encompasses some of the most heavily forested public land in Oklahoma and provides the mixed pine-hardwood terrain that gives Ouachita riding its distinctive southern mountain character: shortleaf pine and oak-hickory forest on the ridge faces, bottomland hardwood and cedar along the creek drainages, and the sandstone outcroppings that define the Ouachita Range at every elevation. Trail routes wind through this terrain and cross the creek drainages that form the headwaters of the Mountain Fork, Kiamichi, and Glover rivers — streams that carve the steep V-shaped valleys characteristic of the folded Ouachita geology. ATVs, UTVs, and motorcycles are permitted on designated routes. No day-use fee; Oklahoma does not require OHV registration for national forest use. Wet weather frequently causes temporary closures on sections of the system — always call the Choctaw Ranger District in Heavener before making a trip (918-653-2991). Daylight hours year-round on open routes.
