Key West, FL → Louisville, KY

Your journey from Key West to Louisville covers approximately 1,267 miles and requires roughly 21 hours of driving time, making it a substantial road trip best tackled over two to three days. You'll begin by heading north out of the Keys on the iconic Overseas Highway (US-1), which connects the island chain through a series of bridges and causeways before meeting the mainland near Florida City. From there, you'll merge onto the Florida Turnpike heading northeast toward the Orlando area, where you'll transition to Interstate 75 northbound—the primary artery you'll follow for much of this journey.

As you progress northward on I-75, you'll experience significant landscape transitions that mark Florida's diverse geography. The drive through central Florida features relatively flat terrain with marshlands and subtropical vegetation, but once you cross into Georgia and Tennessee, you'll begin ascending into Appalachian foothills. You'll pass through or near major cities including Ocala, the Orlando metropolitan area, Atlanta, and Knoxville, each adding an urban stretch that breaks up the highway driving. The elevation gradually increases as you approach Tennessee and Kentucky, with the landscape shifting from pine forests to rolling hills dotted with limestone outcroppings.

Kentucky's landscape offers a pleasant visual transition during the final stretch as you drive through the state's bluegrass region toward Louisville. You'll spend your last few hours on I-75 heading northwest before taking I-64 westbound into Louisville, passing through areas known for horse farms and pastoral countryside. This final leg approaches Louisville through some of the state's most picturesque regions, with gentler rolling terrain replacing the steeper grades you've conquered further south.

For the most pleasant driving experience, plan this trip during spring or fall when temperatures are moderate and visibility is excellent throughout the entire route. Avoid the summer months when heat and afternoon thunderstorms are common across the Southeast, particularly in Florida and Georgia. The winter months bring occasional icy conditions to Tennessee and Kentucky, making roads potentially treacherous, so if you must drive during winter, exercise extra caution and monitor road conditions ahead of time.
