Overview
The Cossatot River is one of the most dramatic rivers in Arkansas and one of the few streams in the South that genuinely earns the word "wild." Its Class IV-V rapids through the Jackfork sandstone gorge have established the Cossatot as one of the top whitewater runs in the region, but the river's appeal extends beyond paddling: the river corridor trail offers hikers access to a geological and ecological landscape that is genuinely different from anything else in the Ouachita National Forest.
The 6-mile out-and-back begins in Cossatot River State Park Natural Area and follows the river corridor through a mix of state and federal land, with the river visible and audible throughout. The trail's 400 feet of elevation gain is spread across the full distance as the path climbs in and out of the river's cut banks and side drainages. The result is a continuous river-view walk with enough terrain variation to stay interesting.
Note: The Cossatot River trail is managed by Arkansas State Parks in the natural area section and by the USFS in the adjacent federal land section. The trail standards and facilities reflect the natural area designation: vault toilets at the trailhead, no developed amenities inside, and a primitive character throughout.
No permit required. Dogs welcome on leash. Vault toilets at the trailhead.
The Route
Miles 0 to 1.5: Trailhead to the upper rapids view. From the natural area parking lot, the trail drops toward the river on a series of steps cut into the sandstone hillside. The Jackfork sandstone that defines the river's geological character appears immediately: massive, rust-colored stone beds dipping at steep angles, the same rock layers that create the river's famous ledge drops and hydraulic features.
The trail reaches the river near the upper section of the Cossatot Falls complex. This is the most famous rapid on the river, a series of Class IV-V drops over sandstone ledges that have drowned several whitewater kayakers over the years. In high water (March through April), the falls are genuinely terrifying: a roar of white water pouring through a narrow sandstone chute. In low water (late summer), the bedrock structure of the falls becomes fully visible, and the geological layering is extraordinary. Stay on the trail above the water's edge; the sandstone near the falls is slick and the currents are dangerous.
Miles 1.5 to 3.0: The river corridor. The trail follows the left bank downstream from the falls, alternating between elevated riverside positions and creek-bottom sections that pass through riparian forest of sycamore, river birch, and cottonwood. This transition, from the upland pine-oak forest to the river edge sycamore grove, happens quickly and visibly as you walk.
River otter have been documented along the Cossatot corridor in recent years, and the river's clean, fast-moving water is excellent habitat. Osprey fish the longer pools below the rapids, and neotropical warblers in spring migration use the riparian corridor heavily in April and May. Louisiana waterthrush, one of the few warblers that breeds along fast-moving streams, nests here and is reliably present from late March through July.
Mile 3.0: Turnaround. The trail continues beyond mile 3.0 as an informal path, but the maintained trail effectively ends here. Return the way you came.
Return: The slight elevation gain on the return, approximately 200 feet over 3 miles, is gradual enough to not feel like a climb. The return walk with the falls sound receding behind you has a different, quieter quality than the outbound.
When to Hike
March through June: The best season for both river drama and wildflower display. Spring rains fill the Cossatot to impressive levels; the falls are at their most powerful from March through May. Check river levels before hiking after heavy rain (see below). Wildflowers in the riparian corridor, native phlox, trillium, and wild columbine, bloom in April and May.
September through November: Fall is the second-best window. Water levels drop to a more approachable visual display, the corridor hardwoods (sycamore, river birch, red maple) turn in October, and the absence of summer humidity makes the walk notably more comfortable. Osprey activity increases in fall as birds move through the corridor heading south.
July and August: Hot and humid. Midday temperatures in the river gorge can reach 95 or higher with full humidity. Early-morning visits (at the trailhead by 7 AM) are manageable. Copperheads and timber rattlesnakes are most active near the river margins in warm months; watch carefully near rocks and logs. Ticks and chiggers are at peak density in summer; treat clothing with permethrin before visiting.
December through February: Hikeable in dry weather. High winter rain events can flood the trail access areas; check conditions before visiting.
Flash Flood Awareness
The Cossatot's watershed is steep and rocky. Flash floods can raise the river 6 to 10 feet in a matter of hours after upstream rainfall. If thunderstorms are forecast for the watershed area, which extends into the Ouachita Mountains to the northeast of Wickes, defer your visit or stay well above the river on the trail's high-bank sections. Do not camp in the river bottom during any period of rain. Review our checking conditions guide for USGS river gauge and NOAA flash flood resources specific to the Cossatot watershed.
Trailhead Access
The Cossatot River State Park Natural Area trailhead is on AR-246 near Wickes, AR, in Polk County. From Mena (the closest town with services), take US-71 south to Wickes and then AR-246 east to the natural area entrance. Total drive from Mena is about 25 minutes.
From Hot Springs, take US-270 west to Mena, then US-71 south to Wickes. Total drive is about 2 hours. Cell service is absent throughout the Wickes and Cossatot area; download maps and weather information before leaving Mena or Hot Springs.
Nearby
The Athens-Big Fork Trail (11 miles, moderate) is accessible about 30 miles north near Glenwood and represents the full Caney Creek Wilderness experience as a complement to the Cossatot river character. The Little Missouri Falls Trail (2.5 miles, easy) near Albert Pike Recreation Area is another southern Ouachita waterfall option, with more accessible swimming. See our Leave No Trace principles guide for riparian corridor protection guidelines.
