Belle Fourche River Campground is the only government campground within Devils Tower National Monument, offering 46 sites (including 3 tent-only sites) on a first-come, first-served basis from mid-May to mid-October.

The campground features flush toilets, potable water, fire rings, and picnic tables at each site, with several sites offering views of Devils Tower itself; RVs up to 35 feet are accommodated, though there are no hookups or dump stations.

Located just 1 mile from the monument's main road, the campground sits among cottonwood trees along the Belle Fourche River and typically has available sites until early evening during peak season (June-September).
