The Florida Keys Self Guided Driving Tour is one of the most scenic road trips in the United States. Stretching over a chain of coral islands, the drive follows the Overseas Highway as it floats above clear blue water, connecting the mainland to the southernmost point of the continental US.

This journey is not about speed. It is about slowing down, stopping often, and letting the rhythm of the islands guide your experience.

History

The Florida Keys have been shaped by the sea for thousands of years, originally inhabited by indigenous peoples who relied on fishing and navigation between islands. European explorers later charted the chain as a strategic maritime route.

In the early twentieth century, Henry Flagler extended his Overseas Railroad across the Keys, a monumental engineering achievement that transformed travel and trade. After hurricane damage, the railway bridges were converted into roadways, forming the foundation of today’s Overseas Highway.

Now recognized as one of the most scenic drives in the world, the Florida Keys Self Guided Driving Tour represents both human ingenuity and the enduring beauty of island landscapes.
