Cottonwood Campground forms a loop near the Little Missouri River. It's a short convenient drive from the visitor's center, and near the beginning of the larger loops that bring you to all parts of the south unit of the park. Bison wander in and around the campground, which offers 76 shady sites . Wild horses can also be found within the park, along the circular drives that take you around the colorful buttes. Sunrises and sunsets are quite beautiful.
