They has some fancies when I was in a pinch to get a site for the next few nights. They were able to accommodate my needs. They have continued to be friendly & helpful throughout my stay.
There are very few trees or shady areas. The tent sites seem to be shadier than the RV sites, who often have air conditioning. The tent sites are also closer to the bathrooms.
There is a pool & other family activities.
This KOA is out among some very small towns. There are few amenities outside of the campground. But I enjoyed a day trip through the Badlands.
