I like this campground. It is right on the Iowa river near a takeout, so you can put in upstream and paddle down, or do as I do and paddle upstream and then back down (works when the water flow is not too swift).

This campground is quiet at night, but I will point out that it is near a popular members-only rifle and pistol range. It is very safe as the range points away from the campground into some large dirt mounds, but you may hear the continuous sound of gun fire during the day.
