Has decent access to the more trafficked entrance to Yellowstone.
We camped in a van, and had plenty of rooms. It has the expected water, sewage and power, and comes with a metal fire pit, which isn't as much of a sure thing as you might expect for these campsites.
The area is decently wooded and green, but will likely be packed during peak months. Plenty of room to walk a dog.
Warning; if you are camping in a tent, be aware that if the game Warden issues a bear advisory, your reservation may be cancelled out of an abundance of caution.
Showers and bathrooms are clean and spacious.
