Yellowstone National Park offers 11 campgrounds with over 2,000 established campsites, with options ranging from developed facilities with full hookups (Fishing Bridge RV Park) to primitive sites with vault toilets.

All campsites must be reserved in advance, with reservations opening six months ahead on a rolling basis; sites fill quickly during peak season (early July-late August).

Several campgrounds provide access to fishing and boating opportunities, including Lewis Lake Campground near a boat ramp and Bridge Bay Campground adjacent to Bridge Bay Marina.
