We have been to the caverns several years ago did not know about the campground.  The camp sites are spready well apart which is nice, they are all paved and well set up and maintained.  The facilities were all great.  The hiking trails in the park were awesome providing adventures and scenery for all levels.  We used the park as a base while we toured the caverns and hiked in the park as well as to visit other nearby sites such as Sierra Vista, Bisbee, Tombstone and Benson.
