The Cossatot River is a premier whitewater destination in western Arkansas, originating in the Ouachita National Forest in Polk County and flowing southward for approximately 89 miles before joining the Little River. This National Wild and Scenic River cuts through the rugged Ouachita Mountains, creating a series of challenging rapids and scenic canyons. Paddling opportunities on the Cossatot range from calm flatwater sections to intense Class IV whitewater.

The river is divided into several distinct sections, each offering unique challenges. The Upper Cossatot, from County Road 31 to Highway 246, provides a 3.4-mile Class II+ run suitable for intermediate paddlers. The next section, from Highway 246 to Ed Banks Road, continues the Class II+ difficulty for 3.1 miles. The crown jewel of the Cossatot is the Falls Section, a 6.25-mile stretch from Ed Banks Road to Highway 278/4. This section features the famous Cossatot Falls, where the river drops 33 feet in elevation over just 1/3 of a mile through a series of six distinct ledges. The Falls offer Class II-IV rapids, with the first drop, known as Cossatosser, requiring particular caution due to a sneaky hole at the entrance. For a more relaxed experience, the Lower Cossatot from Gilliam Lake to County Road 70 offers a 9-mile Class I-II float suitable for beginners and families.

The Cossatot's flow is highly dependent on rainfall, with spring typically offering the most reliable water levels. However, summer thunderstorms can quickly raise water levels, creating exciting paddling opportunities for experienced kayakers and canoeists. The river corridor is home to diverse flora and fauna, including stands of hardwood forests and numerous bird species. Paddlers may spot white-tailed deer, wild turkeys, and even the occasional black bear.

Key access points include the Brushy Creek Recreation Area near Vandervoort, Ed Banks Road, and the Highway 278/4 bridge. The nearby towns of Mena and De Queen offer services for visitors.

Safety is paramount on the Cossatot. Paddlers should always check current water levels, wear appropriate safety gear, and possess solid whitewater skills before attempting the more challenging sections. The Falls area, in particular, requires careful scouting and the ability to execute precise maneuvers.

For those seeking a multi-day adventure, it's possible to combine several sections of the Cossatot, camping at designated sites along the river. However, paddlers should be aware of private property boundaries and obtain necessary permissions. The Cossatot River State Park-Natural Area protects much of the river corridor, offering additional hiking trails, interpretive programs, and camping facilities that complement the paddling experience on this wild Arkansas gem.
