Pros:

Water, sewer, electricity

Level sites

Center point of Yellowstone

Convenience store nearby

Friendly staff

Clean well taken care of campground

Cons:

The site we stayed in was $100 a night

No wood fires allowed

We stayed in loop E for 3 nights while exploring Yellowstone. The campground was very nice and I would say worth $100 a night. It was a good place to leave from each morning to see the sites, we typically would beat the crowds coming from the gates by about an hour to our first destination of the day. As of June '23 loop E is mostly pull through sites for larger rigs. The other two loops are a little tighter but have more tree cover.
