Fort Worth, TX → Key West, FL

Your journey from Fort Worth to Key West spans nearly 1,429 miles of America's most diverse landscapes, taking you through the heart of Texas, across the Deep South, and ultimately down the length of Florida to the southernmost point of the continental United States. You'll depart Fort Worth heading east on Interstate 20, which carries you through central Texas and into Louisiana, passing through Shreveport before crossing into Mississippi. From there, you'll continue on I-20 toward Jackson, then transition to I-55 heading south toward the Gulf region. The final leg takes you through Alabama and Georgia before entering Florida, where you'll eventually pick up US Highway 1—the legendary highway that serves as your gateway to the Florida Keys and ultimately Key West itself.

The terrain and landscape shift dramatically throughout this odyssey. You'll start in the relatively flat to gently rolling plains of North Texas, then move into the swampy, heavily forested regions of Louisiana and Mississippi, where elevation remains minimal and the landscape becomes noticeably greener and more humid. As you push through Alabama and Georgia, you'll encounter the subtle rise of the Piedmont region before descending again into Florida's flat, subtropical terrain. The most dramatic landscape change occurs when you cross the Seven Mile Bridge—the engineering marvel connecting the Florida Keys—which offers your first breathtaking glimpse of turquoise waters and the unique ecosystem of the Keys.

Major cities punctuate your route with opportunities to rest and explore, including Jackson, Mississippi; Tuscaloosa, Alabama; and Jacksonville, Florida, each offering different character and amenities. In Florida, you'll pass through Miami and eventually the charming towns of the Keys like Marathon and Islamorada before reaching Key West itself.

This drive is most enjoyable during Florida's dry season from November through April, when temperatures are moderate and humidity is lower. Summer months bring intense heat and daily thunderstorms that can affect driving conditions, while the Atlantic hurricane season peaks from June through November, making late spring and early fall less ideal for this coastal journey.
