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

Several campgrounds provide access to fishing and boating opportunities, including Lewis Lake Campground which features a nearby boat ramp for canoes, kayaks, and motorboats (requiring permits and aquatic invasive species inspections).

Amenities vary by location but include flush toilets, dump stations, and pay showers at larger campgrounds, though primitive options with vault toilets are also available for those seeking quieter experiences.
