"Island-hopping to land's end, this one-of-a-kind highway offers the promise of radiant seascapes, exotic underwater worlds, and animals found nowhere else in America." Such praise for Florida's famed Overseas Highways––in Reader's Digest coffee table book The Most Scenic Drives in America, no less––inspired me to rent a car in Miami and drive to the Florida Keys this May. I am grateful I did.
The drive from North Key Largo to Key West, the southernmost tip of the continental U.S., spans 42 bridges, hundreds of hotels and restaurants, and countless options for ocean-fun under the sun.

As someone who has sought out the world's most scenic drives––from Scotland's Isle of Skye to British Columbia's Sea-to-Sky Drive, from Ireland's Ring of Kerry to Italy's Amalfi Coast––I would definitely recommend the Overseas Highway, with the following two caveats.
One, don't expect a feeling of remote isolation. Two, embrace the island lifestyle. You won't be alone on Overseas Highway, and you shouldn't be in a rush. The one-lane highway (several stretches do include passing lanes) runs from island to island––or key to key––and is surrounded by countless bars and restaurants, terrific watersports, arguably the best fishing in North America, and a contagious vibe of island fun specific to the laid-back, friendly Florida Keys.
Key Largo
Roughly 30 miles long and just two miles in width, Key Largo is the largest of the Florida Keys. For a cool view of its geologic underpinnings, stop at mile marker 103 on Rte 1, where an expanse of coral has been exposed on the bank of a man-made channel. An outstanding spot for snorkeling and scuba diving is John Pennekmamp Coral Reef State Park, an undersea wildlife preserve.
