Family Friendly Campground Near Red Wing

I want to take my wife and 3 year old camping near Red Wing, so we only have about an hour drive to the zoo, without having to haul the camper the extra hour. I want to find a campground with good playgrounds and bathrooms. Any help would be appreciated.

here ya go. Very nice and by Lake Pepin on the Mississippi.
