This is the only campground in Pawnee National Grasslands, though you can also camp almost anywhere along public land (get a free map from the ranger office or online). This is the beginning and end of the Pawnee birding driving tour and less than an hour from the Buttes themselves. The campground is fairly open but shady. It was empty when I went in late spring (peak birding season). There are bathrooms & water, large cooking pavilions, short hiking trails, a stream, a baseball diamond, and a “museum” showing some historic farm equipment (it’s outdoors and there isn’t too much info, still neat though). There are no stores in this area at all so make sure you have what you need before venturing out.
