The Little Missouri River curves past 76 sites spread across two loops at this established campground within Theodore Roosevelt National Park. Cottonwood fills almost daily during summer months, with odd-numbered sites available for reservation while even-numbered sites operate first-come, first-served. Lee D. notes "the campground fills up almost every day in the summer, even during the week."
Sites range from spacious pull-throughs accommodating RVs up to 65 feet to walk-in tent spots numbered 55-66. The north loop stays open year-round while the south loop operates mid-May through September. Many sites sit among cottonwood trees providing partial shade, though some locations offer little protection from sun and heat. Several sites directly overlook the river, with muddy brown water flowing past campsites. Wild horses frequently graze within view of the campground, and bison regularly wander through, sometimes leaving hoofprints on roads and near facilities.
The campground provides flush toilets, potable water spigots, and a dishwashing station, but no showers or soap in restrooms. Each site includes a picnic table and charcoal grill that doubles as a fire ring—traditional fire pits are not provided. Firewood collection within the park is prohibited; campers must purchase supplies in camping near Medora or bring their own. Cell service reaches most sites with varying signal strength.
Access involves a 20-minute drive from the highway entrance, with some reviewers mentioning rough road conditions. The campground serves as a central base for exploring park trails including the Wind Canyon Trail and Petrified Forest Loop. dallas H. recommends the petrified forest hike as "a must." Summer temperatures regularly exceed 90 degrees with limited shade relief. Arrive before 10:30 AM during peak season for the best site selection.

Natural Features
The Little Missouri River is the central, unifying feature of this wild and broken land where, as a young man, Theodore Roosevelt ranched and hunted in the 1880s. The park is part of both the Northern Great Plains and the West, blending a rich natural beauty with diverse human history. The rugged topography, with its flora and fauna, also provides an opportunity to discover the badlands environment as Roosevelt once did. It is a place to experience a land and way of life that helped shape Theodore Roosevelt's attitudes and philosophy regarding conservation. Cottonwood trees surrounding the campsite turn golden in the fall. Although the campground is moderately forested, most of the campsites are in partial to full sun but visitors can cool off in the cold river when temperatures peak during summer.
