Yellowstone National Park offers 11 campgrounds with over 2,000 campsites, with five major campgrounds (Bridge Bay, Canyon, Fishing Bridge RV Park, Grant Village, and Madison) providing amenities like flush toilets, showers, laundry facilities, and dump stations.

Bridge Bay and Lewis Lake campgrounds provide direct access to Yellowstone Lake for boating and fishing, with boat ramps and permits available.

All campsites must be reserved in advance (except Mammoth's first-come, first-served sites October 15-April 1), and reservations open six months ahead on a rolling basis.
