We pulled in the evening and just stayed for one night but it was a nice little spot.  Small campground but seems like you could easily pull off and camp nearby if it were full.  Pit toilets were clean.  No water on site and no stores nearby so make sure to bring your water with you.  Recommend following the signs and not google maps - google was telling us to drive down a rough road but the signs took us to a road that was much easier... still gravel and washboard in spots but no major potholes. Our main issue was the lack of phone service - according to this listing there is service and we had some service driving through the wildlife refuge but did not have service at the actual campground (we have AT&T).
