Level spots, water & electric. There is a dump station on site. Great Verizon and T-Mobile speeds here.
You must register online, and it's not easy to find the link. Here it is: https://properties.camping.com/dakota-city-cottonwood-cove-campground/Reservations
There is another review which says you pay the camp host, but they told me it must be done online now. The price in 2025 is $30/night for 30A (not sure if 50A is more), which I think is a little high considering you can camp in some beautiful spots for $30.
There is some kind of bathroom or shower house on site, but it requires a code and when I registered online it did not give me the code. There is quite a bit of traffic coming in and out of the small campground. Almost every camper has at least two cars parked with it, and people keep coming and going.
