The drive down the Overseas Highway
Key West sits about 160 miles south of Miami, and the journey along US-1 is half the adventure. The Overseas Highway leaps island to island across the Seven Mile Bridge, with the Atlantic on one side and the Gulf on the other. Most visitors book a round-trip day trip with comfortable coach transport, which handles the roughly 3.5-hour drive each way and leaves you free to soak up the views. Departures leave Miami early to maximise time on the island.
