Yellowstone National Park offers 11 campgrounds with over 2,000 campsites, with reservations required well in advance as sites fill quickly, especially July-August.

Campgrounds vary from developed facilities with flush toilets and showers (Bridge Bay, Canyon, Grant Village) to more primitive options with vault toilets, accommodating everything from tent camping to large RVs up to 95 feet.

Several campgrounds provide direct access to fishing and paddling opportunities, with boat ramps available at Bridge Bay and Lewis Lake, though all visitors must obtain required permits and pass aquatic invasive species inspections before launching watercraft.
