Yellowstone National Park offers 11 campgrounds with over 2,000 established campsites, all requiring advance reservations (except Mammoth, which offers first-come, first-served sites October 15 - April 1).

Several campgrounds provide access to fishing and paddling opportunities, with amenities ranging from basic vault toilets to full facilities with flush toilets, showers, and dump stations; Bridge Bay and Grant Village campgrounds are particularly well-suited for boating on Yellowstone Lake.

Reservations open six months in advance on a rolling basis, and sites book quickly, so early planning is essential for summer visits.
