The main campground in Theodore Roosevelt’s more-visited South Unit, Cottonwood sits along the Little Missouri River, right along the park’s scenic loop road, with free-roaming bison and wild horses regularly seen from camp. Sites offer vault toilets and potable water, no hookups, and the campground’s location makes it the natural base for exploring the South Unit’s badlands overlooks and short trails without much driving. Given the South Unit’s popularity relative to the more remote North Unit, this campground sees steadier demand, though it rarely reaches the intense competition levels of more famous Western parks.
