Key West, FL → Savannah, GA

Your journey from the tropical southernmost tip of Key West to the historic riverfront of Savannah spans approximately 678 miles and takes around eleven and a half hours of driving time. You'll begin by taking US Route 1 north from Key West through the stunning Florida Keys, a unique stretch of highway that connects a chain of islands via bridge after bridge, offering ocean views on both sides before you reach the mainland at Florida City. From there, you'll merge onto the Florida Turnpike heading north toward Miami, then transition to Interstate 95, which becomes your primary corridor for most of this drive as you cut through Florida's eastern seaboard. This interstate passage through Florida gives way to Georgia, where I-95 continues northward through mostly rural, tree-lined sections before delivering you to Savannah's historic downtown area.

The landscape transformation along this route is dramatic and worth noting. You'll depart from the flat, subtropical islands and mangrove wetlands of the Keys and Keys-to-mainland transition, traveling through Florida's gentle coastal plains with minimal elevation change throughout the entire state. As you push into Georgia on I-95, the terrain remains relatively flat, though you'll begin noticing the transition toward the coastal Low Country, with increasingly frequent marshlands and swampy areas visible from the interstate, particularly as you approach Savannah.

Your drive takes you through or near several significant cities and regions that offer strategic break points. After leaving the Keys, you'll pass through the greater Miami metropolitan area—a major urban stretch requiring patience during peak traffic hours—before entering more rural central Florida. Further north, you'll skirt past Daytona Beach and the Space Coast region, then continue through Jacksonville, another substantial city where I-95 tends to congest.

The best time to undertake this drive is during Florida's dry season from November through April, when temperatures are mild and afternoon thunderstorms are less frequent. Summer months bring intense heat, humidity, and daily afternoon storms that can reduce visibility and make the journey less enjoyable, while hurricane season from June through November adds an element of unpredictability to your travel plans.
