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

Campgrounds vary in amenities and accessibility, with options ranging from primitive sites with vault toilets to developed facilities with flush toilets and showers; most are seasonal, opening spring through fall.

Anglers and paddlers should note that several campgrounds provide access to fishing and boating opportunities, particularly Bridge Bay and Grant Village near Yellowstone Lake, though reservations typically book months in advance.
