we camped here from June 12-15. The campground only takes limited reservations and the rest first come first served. We arrived around 8.30am and waited in line for around an hour but ended up getting a spot. Good location as is central to the rest of Yellowstone. $20 a night , no showers though so if you are staying more than a couple of days we drove to a campground nearby which had pay showers $4 had a couple of bison visit during our stay and all campsites have bear lockers
