Belle Fourche River Campground is Devils Tower National Monument's only in-park campground, offering 46 first-come, first-served sites along the Belle Fourche River with water access, flush toilets, fire pits, and picnic tables.

The campground operates mid-May through mid-October and accommodates RVs up to 35 feet, though it has no hookups or dump station.

Located directly adjacent to the river with scenic tower views, it provides a base for accessing hiking trails and wildlife viewing in the monument area.
