Tailwater is a 49-site campground in Mammoth Cave National Park. It accommodates RVs, tents, and trailers, with sites for RVs up to 115 ft. 48 of the 49 sites have hookups. Around 48 sites are shaded. Pets are welcome at some sites, most sites have a fire pit, and 2 sites are ADA-accessible. Maximum party size is 50. Some dates carry a multi-night minimum stay. Like most popular Recreation.gov campgrounds, Tailwater books up months ahead, but cancellations open regularly. Campsite Sniper watches the targets you choose and alerts you when one frees up. We never book, hold, or pay for reservations; you book directly on Recreation.gov.
