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 require advance reservations (except Mammoth's first-come, first-served winter sites), and visitors should book early as sites fill quickly, especially during peak season (July-August).
