Yellowstone National Park offers 11 campgrounds with over 2,000 established campsites, all requiring advance reservations (except Mammoth's first-come, first-served sites October 15-April 1).

Several campgrounds provide access to fishing and paddling opportunities, with Lewis Lake Campground featuring a boat ramp for canoes, kayaks, and motorboats (requiring permits and aquatic invasive species inspection), while others like Bridge Bay and Grant Village offer lake access near Yellowstone Lake.

Amenities vary by location but include flush toilets, dump stations, and ranger programs at developed sites, with nightly fees ranging from $20-$94.
