Yellowstone National Park offers 11 campgrounds with over 2,000 campsites, with most requiring advance reservations through Recreation. gov or Yellowstone National Park Lodges.

Campgrounds range from basic vault toilet sites to developed facilities with flush toilets and showers, with several providing access to fishing and paddling opportunities on park waters including Yellowstone Lake and various rivers.

Key amenities vary by location but include bear-proof food storage (mandatory), picnic tables, fire rings, and dump stations at select campgrounds, though most are seasonal (May-October) with Mammoth being the only year-round option.
