Rockcastle County is a rural, beauty-filled region of deep valleys and wide-open farmland situated in south-central Kentucky, and is traversed by I-75. The county is named for the Rockcastle River, in turn named for its majestic sandstone and limestone cliffs; a portion of the river has a well-deserved state-level Wild and Scenic designation.
The county seat, Mount Vernon, is a bustling center for government and health services, and is home to the Renfro Valley Entertainment Center and Kentucky Music Hall of Fame and Museum.
