Belle Fourche River Campground is the only government campground within Devils Tower National Monument, offering 46 first-come, first-served sites (mid-May to mid-October) with water access, flush toilets, fire pits, and picnic tables along the Belle Fourche River.

The campground accommodates RVs up to 35 feet and provides direct views of Devils Tower, making it an ideal base for hiking and exploring the monument's 3. 7-mile loop trails.

Sites cost $20-30 per night and typically fill by early evening during peak summer season, so arriving early is recommended.
