Gatlinburg to Natchez Road Trip: Deep South Journey

Did you know that the drive from Gatlinburg, TN to Natchez, MS roughly traces the path of the old Jackson Highway, a early 20th-century auto trail? This 540-mile route takes you from the highest peak in the Smokies (Clingmans Dome at 6,643 feet) down to the Mississippi River at 60 feet elevation. The journey spans about 8 hours and 45 minutes of pure driving, but you'll want at least three days to savor it.

The route follows US-441 south to I-40 west, then I-840 around Nashville, before dropping onto US-31 and finally the Natchez Trace Parkway. The Trace itself is a 444-mile scenic road that runs from Nashville to Natchez, but we'll join it near the Alabama border.
