Free camping with wildlife
Campground is basic. Only 2 (very clean) vault toilets, no water or electricity. I got there a little before 3pm on mother's day; it was full by 8. Only a handful of sites have sun covers over the picnic tables. You will be very close to other campers. Most are respectful. I would just recommend getting there before dark to keep from disturbing everyone. Prairie dogs galore in the center and on the periphery of the campground. My dog was fascinated by them. As noted by others, you will most likely be serenaded by coyotes and have morning visits from the bison. I also heard wild turkeys off in the woods.
