Pennyrile Forest Trail Kentucky

The Pennyroyal Plateau or Pennyroyal Region, often spelled Pennyrile, is a large physiographic region of Kentucky that features rolling hills, caves, and karst topography in general. It is named for Hedeoma pulegioides, a wild mint that grows in the area. It is also called the "Mississippian Plateau," for the Mississippian geologic age in which it was formed.
