Clay County Park is located 4 miles outside of Vermillion South Dakota. It is secluded and peaceful. There were a few down falls. A lot of the sites were taken by either people who lived there full time or people who leave their camper there for the whole summer. Also the camp ground hosts weren’t friendly like all the other camp grounds we visit. But it was peaceful and pretty. The sites were very nice sized. You didn’t feel like you were right on top of each other. They are Electric only and there is drinking water and sewage dump close by. There was 2 nice restrooms and 1 vaulted toilet. There was a few trails, 1 leading to the Missouri River. Down the road (not far) is a nice shelter next to the river and a boat ramp.
