Close to the park, but in the boonies. We had a friend working at Pahaska, so it was convenient to visit him. Quiet.

This is a nice, quiet campground, close to Yellowstone NP. We enjoyed the wildlife and the site size was generous. There is no cell coverage but that is tolerable for a few days.

The campground was quiet and our site was nice and shaded. It was a back in site but very easy to back into. We were next to the out house and the camp hosts kept them very clean. The sites had a table, bear box, and fire ring. The campground was on the river too. It is located 3 mi from the entrance to Yellowstone.
