Stayed for 3 nights. Very shady, but does not have sewer or water hookup. 30 amp electric service. Grounds are well maintained and the restroom and shower facilities are very up to date but heavily used. Sites are closer than I like. Park has nice trails and bluffs. Bison are within the park but did not see. Rangers and staff very friendly. Would be great for overnighter. The most irritating thing about the park were the next door neighbors who let their five dogs use our campsite as an area for deification. People with pets need to be respectful of others. I have come to the conclusion that all pets should be banned from public lands.
