we arrived at this campsite around 4:30 on a Friday in June. There are three large loops, each with plenty of sites of pretty good size. Loop A was mostly reserved, while Loops B and C were practically empty. The sites are well maintained, bathrooms are clean and all are close to water for some awesome fishing. There is a free campsite maybe a mile towards the West Yellowstone entrance on the opposite side of the road on Beaver Creek Road. This site does charge a fee.
