Could’ve Been So Much More
This could have been a much better park. Very new and modern looking. Our site was very far from the bathrooms and I asked to be moved closer. They said that they weren’t allowed to move us. The place was 30% booked. My site was very unlevel. The sewer was at the extreme uphill side of the site. Had to block traffic to dump before I could park. Poop won’t run uphill. Will not stay here again. The bathrooms were nice.

Great Place With Lots To Do
This was just a one night stop on the way to Mount Rushmore but it was beautiful. Lots to do with kids. Even a water park down the street. Campground was clean and quiet. Playground, lake with beach and a dog park. The only thing is the trees are young on and near the sites there is not much shade. Great place overall.

Clean Park
Nice, clean park with its own store and gas station. Sites are a mix of paved and gravel but roads are paved and sites are spaced a good distance apart.

Nice Spacious Park
Nice park with some paved sites, water views and friendly staff. Store is also a gas station and believe it or not they do not jack up the price on anything. Water park next door and "Field of Dreams" movie site is around a hour away. We enjoyed our stay.

Nice Place
Friendly staff. Clean campsites and lots of things to do. Clean beach and clean playground. Quiet time at 10pm was enforced and much appreciated! We enjoy peace and quiet when it's dark. Clean shower houses. Nice conscience store and fuel station on site. Close to water park. Will most likely come again.
