For $17 a night, try and get a site right on Tensleep Creek. Sites are pretty, and private-ish with lots of trees (some good for hammocking, some not). Everything was really well maintained to the point of everything looking new. All the usual amenities of picnic tables and fire pits and grills, PLUS there are pretty awesome prep tables for cooking and a lantern pole at each site, with super clean vault toilets where the camphosts have set pots of flowers to improve the setting. I suggest getting a site on the backside of the loop away from the road. The campground hosts were great, checking on campers a couple of times in the early evening and again in the morning. They rolled around in their golf cart stocked with firewood for sale so you didn’t have to hike back to the top of the hill to get your wood. There are some great family activities areas in the campground with horseshoes, cornhole, and other games set up in a central activities area.
