I stayed for 3 nights on Loop 5. I would definitely stay again, but only during the week. I like to camp to find a bit of solitude and quiet. The first night I was there, the loop was fairly empty, only a few campers. It was very peaceful and we were able to see a ton of stars. I even heard a pack of coyotes running through the mountains that night. 

The next two nights were a Friday and Saturday, and all the site were booked for those nights. You could hear generators running in the distance and lots of dogs barking. The site right next to ours had people up playing music and singing until midnight. 

The bathrooms were clean and you had plenty of water pressure. The bathhouse on loop 5 had two stalls, one with a toilet and large shower and the other with just a toilet. Bathrooms in the other loops were all private, (separate area for toilet and your own shower room).
