St. Francis is a beautiful Missouri state park, not to mention campground.  It features many access points to its anchor, the BIg River, picnic areas, multiple pavilions and some fantastic trails.  I grew up here, and I am biased toward it, but we camped many places, and it remains one of my favorites then, and now.  The campground has more of a communal vibe, for better or worse, depending on your perspective.  If privacy is your main concern, you may be better served looking elsewhere, but I have always enjoyed the friends I have made there, both young and old due to the proximity of the campsites and the many programs offered there by the Conservation Department.
