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

Several campgrounds provide access to fishing and boating opportunities, including Lewis Lake Campground (near a boat ramp for canoes, kayaks, and motorboats) and Bridge Bay Campground (adjacent to Bridge Bay Marina).

Amenities vary by location but include dump stations, showers, laundry facilities, and stores at select campgrounds; generators are permitted at RV sites only (8am-8pm), and a 14-day stay limit applies June 15-Labor Day.
