Full hookups and nice sites.  A bit close but workable. (Really typical for a private RV park)

Spent four days the end of August.  Weather was pleasant and campground was very clean.  Spacing not too bad, but I like State Parks as you get privacy.  You are very close to town and entrance to Yellowstone National Park.  Has full hookups to include cable TV.

Drove to the upper area with 35 foot 5th wheel and you need 4-wheel drive.  A bit dicey in one area but worth the trip.  (There is a sign coming off the main road for any RV longer then 30 foot to got the the next site up the road another mile.)  Host at site did not say anything about our stay (3 nights).  A bit smoky due to forest fires in CA, but great sights/views early in the morning.  We stayed two nights three weeks later as we headed back south.  Stayed in lower area and it was also just as great, although views not as nice.
