Yellowstone National Park offers 11 campgrounds with over 2,000 campsites, all requiring advance reservations (except Mammoth's first-come, first-served sites October-April).

Campgrounds range from developed facilities with flush toilets and showers to primitive sites with vault toilets, accommodating both tent and RV camping with various size restrictions.

Key amenities include dump stations at most locations, food storage lockers for bear safety, and access to fishing, hiking, and boating opportunities throughout the park.
