The Cossatot River is an outstanding example of an upland river in the Ouachita Mountains. As it flows southward, the river cuts through a series of east-west oriented ridges, producing magnificent rapids and waterfalls. The natural area supports at least two fish species endemic to the Little River system and numerous special plant species, including Browne’s waterleaf. The area is managed cooperatively with Arkansas State Parks (ASP). Portions of the site have been developed to enhance public visitation and environmental education opportunities. These developments include a visitor information center, a canoe launching area, solar restrooms, picnic areas, primitive camp sites, a hiking/nature trail, and a barrier-free pedestrian river walkway.
