Loved this place. Less than 10 minute walk to the Visitor Center, restaurant, ice cream shop and camp store. US Post Office on site will stamp your mail with the Mammoth Cave cancellation stamp. Many sites are drive through, no electric or water at site, lots of trees so little solar power collection. Large sites with space between. The caves are not fully open with COVID but the self guided tour was great. Rangers around to answer questions. Hiking paths are of every type, easy paved to high rugged. Wild life is mostly white tail deer, squirrels, chipmunks and birds. Easily could spend a week here.
