With divisions varying depending on the source and purpose of the division, there is no absolute official definition of Kentucky's regions. For instance, Kentucky's department of Travel and Tourism divides the state into four large regions with additional subregions, whereas the University of Kentucky divides the state into six physiographic regions.
The Kentucky Department of Travel and Tourism divides the state into nine regions, named according to the attractions in the area and organized into four sections. Eastern Kentucky has two regions: Kentucky's Appalachians and Daniel Boone Country. Northern Kentucky has three regions: Northern Kentucky River region, the Bluegrass region and Bourbon, Horses and History. Southern Kentucky has two regions: Kentucky's Southern Shorelines and Caves, Lake and Corvettes. Finally, Western Kentucky has two regions: Western Wetlands and Bluegrass, Blues and BBQ.
The University of Kentucky's geography department, on the other hand, divides Kentucky along geographic grounds and describes six major regions. The Bluegrass region in Eastern Kentucky has rolling hills and fertile soil over a limestone base. The Eastern Kentucky Coal Field covers the Appalachian area of Kentucky in the East of the sate. The Knobs region covers a thin band of cone-shaped hills bordering the Bluegrass region and separating it from the Mississippian Plateau region, which extends to the Mississippi Embayment and Western Kentucky Coal Field.
