Key West, FL → Nashville, TN

Your journey from Key West to Nashville stretches across nearly 1,112 miles of remarkably diverse American terrain, beginning at the southernmost point of the continental United States and ending in the heart of Tennessee's rolling highlands. From Key West, you'll head north on the iconic Overseas Highway (US-1), a breathtaking coastal drive that connects the Florida Keys via a series of bridges and causeways before reaching the mainland near Homestead. Once you rejoin the mainland, you'll transition to Florida's Turnpike heading northbound, then connect to I-75 near Ocala—a crucial interstate that becomes your primary route for much of the journey through Florida, Georgia, and into Tennessee. This combination of highways eventually feeds into I-24 near Chattanooga, which carries you the final stretch into Nashville.

The landscape transformations along this route are striking and worth noting as you drive. The initial Overseas Highway segment offers unparalleled water views and low-lying coastal elevation before you climb gradually into Florida's interior, where pine forests and swampland characterize the terrain around central Florida. As you press northward through Georgia on I-75, you'll notice the landscape becoming increasingly hilly and forested, with the Appalachian foothills becoming more pronounced as you approach Chattanooga. The final leg on I-24 takes you through genuine mountain terrain with notable elevation changes, particularly as you wind through the Tennessee valley toward Nashville's elevated plateau setting.

Key stops and notable cities punctuate this drive, with Miami serving as a major urban center shortly after leaving the Keys, followed by the sprawling Tampa Bay area. Georgia offers the bustling Atlanta metropolitan region—which you'll skirt on I-75—while Chattanooga provides your gateway into the Tennessee mountains with its dramatic riverside setting. Nashville awaits as your final destination, a vibrant city known for its music heritage and increasingly cosmopolitan appeal. The drive combines stretches of monotonous interstate driving through central Florida with genuinely scenic sections, particularly once you enter Georgia and Tennessee's more rugged topography.

The best time to undertake this drive is November through March, when Florida's oppressive summer heat and humidity have subsided, and the northern portions remain relatively mild. Summer months bring intense heat throughout Florida and afternoon thunderstorms that can develop rapidly, while the mountain sections occasionally experience
