and the warm shallows of the Gulf of Mexico,

the Florida Keys are strung together by the Overseas Highway,

an engineering marvel which arcs across 44 of the archipelago's 17 hundred keys.

There's a saying in The Keys,

that for every mile travelled down the Overseas Highway,

the real world gets left further behind.

After the one-hour drive from Miami,

celebrate your arrival at the Upper Keys by kicking back at Caribbean Club,

the setting for the Bogart and Bacall movie classic, Key Largo.

From Key Largo, follow the mile markers south to Plantation Key,

the sleepy gateway to Islamorada,

a 20-mile stretch of six keys known as the sportfishing capital of the world.

At Windley Key Fossil Reef Geological State Park,

follow the hammock trails to quarries where a century ago,

laborers cut great blocks of coral for Henry Flagler's overseas railroad.

Nearby, at the Keys History and Discovery Center

learn more about this incredible railway, which ran all the way to Key West

until it was forever derailed by the 1935 Storm of the Century.

Hurricanes have played a recurring role in the Keys' history.

Pride of place at the Discovery Center are incredible artifacts

salvaged from the ill-fated Spanish Fleet of 1733,

whose treasures were blown across an 80-mile stretch of Keys' coastline.

Clear waters, rich marine life,

and the lure of sunken gold have long made the Keys a magnet for divers.

While you're in Islamorada, be sure to drop into the History of Diving Museum,

which celebrates humankind's never-ending quest

to explore a world that's even less well-mapped than the moon.

Islamorada offers treasure far more accessible

than the Spanish galleons which line the coast.

You'll find it in the liquid gold creations of Florida Keys Brewing Co.

And in the golden flame of the artisan's torch at Rain Barrel Village.

It's in the sun-kissed salsa which graces the catch of the day.

And in the silver flashes of hungry Tarpon at Robbie's Marina.

But most of all,

it's in the stiffening breeze which shapes the evening clouds

and carries the promise of even more adventures.

From Islamorada,

leave the Upper Keys behind and begin your Middle Key wanderings

amid the gumbo-limbo, crabwood and mangroves of Long Key State Park.

A few miles south in Marathon, top up your tank with a Lobster Rueben.

Then make tracks to Crane Point Hammock,

where you'll find 64 acres of trails, historic sites, and a nature center

that helps the Keys' injured birds find their wild wings again.

The spirit of conservation continues just down the highway,

at Marathon's Turtle Hospital, which specializes in the rescue,

rehabilitation and release of some of the keys' most chilled-out visitors.

When you're ready to continue your migration south,

cross the breathtaking Seven Mile Bridge, to the Lower Keys.

Pull over at Bahia Honda State Park,

where a five-minute rest stop can easily melt into five hours of bliss.

After drying off, head to the end of the Overseas Highway to Key West.

Known to fun-lovin' locals as the capital of the Conch Republic,

Key West is more than just a stunning destination, it's another state of mind.

Key West's 7-square miles are flat,

so swap out the rental car for flip flops and head for Duval Street,

which runs right through the heart of the Old Town.

Start at the street's Northern end,

at Mallory Square, where cruise-ship day-trippers

fan out into the city with margaritas on their minds.

Follow Duval south, along a pastel streetscape

where the architectural styles of the Bahamas and Spain

rub shoulders above the passing parade of souvenir shoppers and bar hoppers.

At Duval Street's southern end, wade into the waters of South Beach,

where Tennessee Williams took his morning swims during his 34-year stay.

Storytellers have long been lured by Key West's freewheeling spirit,

and no writer embraced that spirit more than Ernest Hemingway.

Just a block off Duval Street,

call into Hemingway House where the Pulitzer and Noble prize-winning author

spent some of his happiest and most productive years.

Right across the street, climb the stairs of the Key West lighthouse,

which often guided the writer home after a long night of carousing.

Key West has also been a favorite with Presidents.

Down by the waterfront look for the pearly walls of the Little White House,

the winter headquarters of President Harry S Truman.

Just up the street, be dazzled by Spanish gold, silver and emeralds

in the Mel Fisher Maritime Museum,

named after the treasure hunter who scoured the seafloor

for 16 long years before finding the wreck of the legendary galleon, the Atocha.

You could spend days exploring Key West's architectural,

historic, and creative treasures, but as often happens in the Keys,

it's Mother Nature who steals the show.

Dive into the Key West Eco-Discovery Museum

and learn the secrets of Florida's rich undersea and intertidal worlds.

Then head to the Historic Seaport, raise the mainsail,

and head off for an afternoon of snorkelling on North America's only living reef.

The road may end in Key West, but the keys continue for a further 70-miles,

to Dry Tortugas National Park.

Take the 2-hour cruise, or treat yourself to a 40-minute seaplane flight,

and step ashore at one of the USA's most spectacular national parks.

Spend the day exploring the casements and parade grounds of Fort Jefferson,

whose 16 million bricks were all shipped from the mainland.

Then pull on your facemask and snorkel in some of the clearest,

most pristine waters on the planet.

All that sun and sea spray can make a person thirsty.

So after a day on the high seas, tie up back at Key West,

and whet your whistle on a rum-tasting tour or in a Mojito-making class.

If free-flowing cerveza is more your thing,

just follow the sounds of good music and laughter to

iconic watering holes like the Green Parrot,

a favourite with locals and blow-ins for over 125 years.

But there's no greater show in Key West, no better time to be had,

than at Mallory Square at dusk.

This is where it all comes together,

the characters…the music…the flavors of the Keys.

As the sun hangs above the horizon like a molten Spanish doubloon,

bathing every face with its golden glow, a spirit is shared by all.

It's a spirit which says, “look at us, we've made it,

we escaped the Real World, and found paradise”.
