We camped here for 2 nights with our dogs. 

The campground has 4 loops. We were in the B loop. All the sites come with a stone bench and table and a fire pit with a cooking grate. The campsites provide a lot of shade, which is great in the summer month. They are not very private but spacious. Some sites have poor drainage after it rained. It makes it difficult to set up your tent. 

Just in case you forgot something, there is a camp store at the entrance. Do not buy the manufactured firewood product!! No one was able to get it to burn. 

If there was any disturbance, the rangers really took care of it right away. 

The bathrooms seemed fairly new and were very well maintained. Not so the showers, that were pretty run down and old. They were outside the campground, but within walking distance. In order to take a 4.5 min shower, you need $1.50. We thought it is ridiculous! 

Be cautious around the deer in the campground. They don't fear humans and therefore they could be dangerous. 

To get to the visitor center or the tour starting point, it's about a 10 min walk. The park also offers a lot of short trails and interesting history. It is definitely worth a trip. The cave was spectacular. They offer many different tours. It is the longest cave system in the world and there is a lot to explore.
