Yellowstone National Park offers 11 campgrounds with over 2,000 campsites, with several located near Yellowstone Lake providing access to boating and fishing opportunities.

Bridge Bay Campground, situated directly on Yellowstone Lake, features a marina and boat launch, making it ideal for paddlers and anglers; Lewis Lake Campground also provides boat ramp access for canoes, kayaks, and motorboats with required aquatic invasive species inspections.

All campsites require advance reservations (except Mammoth's first-come, first-served sites October-April), with amenities varying by location but typically including flush toilets, dump stations, and food storage lockers for bear safety.
