Belle Fourche River Campground is the only government campground within Devils Tower National Monument, offering 46 first-come, first-served sites ($20/night) with water access, flush toilets, fire pits, and picnic tables from mid-May to mid-October.

Located on the banks of the Belle Fourche River, the campground provides direct views of Devils Tower and serves as a base for hiking trails and wildlife viewing, though it offers no RV hookups and accommodates vehicles up to 35 feet in length.
