Yellowstone National Park offers 11 campgrounds with over 2,000 campsites for tent and RV camping, with most requiring advance reservations through either Yellowstone National Park Lodges or Recreation. gov.

Amenities vary by location but include options with flush toilets, showers, dump stations, and bear-proof food storage, with several campgrounds providing access to fishing and boating opportunities on Yellowstone Lake and nearby streams.

Mammoth Campground is the only year-round option and operates first-come, first-served during winter months, while other campgrounds typically open seasonally from May through September.
