Maintained by the Kentucky Department of Parks, Kentucky's system of 49 state parks has been referred to as "the nation's finest" and experiences more repeat business annually than those of any other U.S. state. The state's diverse geography provides a variety of environments to experience. From mountain lakes to expansive caves to forests teeming with wildlife, park-goers have their choice of attractions, and they are all within a day's drive of each other. Unless otherwise specified, data in the following lists are taken from Kentucky State Parks by Bill Bailey.
