We stayed in Prairie Dog State Park for one night on our way back home from Colorado and were pleasantly surprised with what a nice park this was. We stayed in a primitive site. The sites were spacious and had a wonderful shelter! The vault toilet, however didnt look like it had been swept in awhile as it had a LOT of bug carcasses. But otherwise a nice place to stay. Something for everyone, tents, RVs, campers. Beautiful views!
