During the off-season, sep thru mid May (when the kids are in school) is the perfect time to stay at this state park. I do not stay during the high occupancy times since I don't like crowded camping, and this park is close to Sioux Falls and right off I90, which can make this place busy. There is a very nice sand beach, playgrounds, fishing, star gazing, and four campgrounds. I would not camp at the west side north area since it is very new and has very few trees. Great park if you're just passing through. Residents of South Dakota love their camping, so book a site as early as allowable. I would recommend the east campground. Very pretty. There are four very nice tent only sites in one area. I would give it five stars but to many people during the season.
