Ya gotta stop one exit back at horse cave and visit Kentucky down under.
It is a Austrailan theme zoo with a tour by boat thru horse cave. The twins will go wild in the wallabe petting zoo.
Onyx cave campground has it's very own cave tour. There were some archilogical finds made there in the 60's. So it has a history. This on has interested me every time I go to Glasgow to visit my mom. I think this would be my choise for a private campgrounds.
Barren River is almost 40 miles south of Mammoth caves but Vic and I have driven thru and it is a horse nut and boaters dream. Riding paths and rental livery for guided riding tours. I am guessing pony rides too.I think they have to pipe in sunlight to the heavily shaded campgrounds. It was chained off for the winter when we were down so we couldn't actually enter the camping area. And did I say boats these are knock your eyes out gorgeious 53' yachts
Mom house backs up to highway 31 not even 6 miles from the barren river park entrance.
