The Mammoth Cave NP campground is clean, full of trees, and has campsites adequately spaced between one another. We camp in a small RV, and we go out in the woods for the peace and quiet of nature. This park allows generator use from early morning till late evening (10:00, I seem to remember). To be blasted by generator noise almost constantly is not necessary. I truly feel sorry for the many tent campers who use the park. This problem could so easily be eliminated by greatly limiting generator use hours or by having a camping loop dedicated to those who wish to use generators. Other than that, the campground is a perfect choice for easy walking to the Mammoth Cave visitor center, plus a nice camp store and a post office. The price is, as with all national parks, a bargain. No hookups-- but there is a showering facility for public use at a small fee.
