Key West, FL → Memphis, TN

Your journey from Key West to Memphis traces an ambitious path northward through some of America's most diverse landscapes, covering approximately 1,148 miles in roughly 19 hours and 15 minutes of driving time. Beginning at the southernmost point of the continental United States, you'll head north on US Route 1 through the Florida Keys, a stunning 113-mile stretch that serves as the scenic gateway to this epic road trip. Once you reach the mainland near Miami, you'll transition onto the Florida Turnpike and then connect to I-75 North, which becomes your primary corridor for the next several hundred miles as it carries you through central Florida and into Georgia.

As you progress northward on I-75, you'll experience a gradual but noticeable shift in landscape and elevation. The flat, subtropical terrain of Florida gradually gives way to the rolling hills and forests of Georgia, and later the Appalachian foothills of Tennessee. You'll pass through or near several significant cities including Atlanta, Georgia, where urban driving requires focused attention before you break back into more rural stretches. The drive through Tennessee offers increasingly elevated terrain, with subtle mountain views becoming more pronounced as you approach Memphis. Most of this route follows major interstates, minimizing navigation complexity, though you should be prepared for congested urban areas around Atlanta and the various interchange systems that characterize I-75.

The best time to undertake this lengthy drive is during the mild months of late fall or early spring, roughly October through November or March through April, when Florida's heat isn't oppressive and northern Tennessee weather remains manageable. Summer months bring intense heat and afternoon thunderstorms throughout the South, potentially slowing your progress, while winter rarely presents serious obstacles but occasional ice in Tennessee requires caution. Plan for at least one overnight stop if you want to drive safely, perhaps breaking the journey in Georgia or northern Florida, allowing you to arrive in Memphis refreshed and ready to explore this vibrant river city.
