Kentucky is perhaps best known for its horses, bluegrass and bourbon, but beneath the rolling hills of the state's Green River valley lies a natural treasure unmatched in the world: Mammoth Cave. With 390 miles of passages, it's the world's longest cave, more than double the length of its closest competitor. And now, thanks to the nine-mile Mammoth Cave Railroad Bike & Hike Trail, this geologic wonder is accessible by rail-trail.
