Yellowstone National Park offers 11 campgrounds with over 2,000 established campsites, with options ranging from developed facilities with full hookups at Fishing Bridge RV Park to primitive sites at locations like Slough Creek and Lewis Lake.

All campsites must be reserved in advance (except Mammoth's first-come, first-served sites October 15-April 1), with reservations opening six months ahead; popular sites fill quickly during peak season (July-August).

Several campgrounds provide convenient access to fishing and paddling opportunities, with boat ramps available at Bridge Bay and Lewis Lake for water recreation.
