Worth a stop for sure, but don't plan on spending more than a few hours here! It can get pretty hot or windy.
Definitely in the middle of nowhere... we got lost about three times! But a beautiful campground. It is smallish, but the view of the water is great! No showers or water though.
Slept here for a night while driving through South Dakota. Excellent location, make sure you stop at the Corn Palace! Overall a good campground (safe, clean, etc.) PS. Great showers!
