From the great Smoky Mountains to the banks of the Mississippi, Tennessee has four distinct regions, each one culturally and geographically diverse. Knoxville, at the headwaters of the Tennessee River, is the anchor of the Northeast, home to emerging industries and the University of Tennessee. In the Southeast, the city of Chattanooga offers a beautiful downtown, as well as an extensive greenway system, including five miles of riverwalk meandering through the historic art district. Set in the heart of the state, Nashville is defined not just by music, but also by its three professional sports teams and thriving economy. To the west, Memphis has an irresistible soul that's drawn people to visit Graceland and to enjoy the rhythm of life in the cradle of the blues for decades. And just across the Mississippi into Arkansas, Little Rock offers down-home charm and cosmopolitan bustle.
