Detour #21: Transfagarasan Highway, Romania
Jeremy Clarkson, Richard Hammond and James May have a lot to answer for. Before Top Gear visited Romania, the Transfagarasan Highway was near enough a secret.
Detour #20: Targa Tasmania, Australia
For the past 27 years, the island state of Tasmania has given itself over as playground to a rally quite unlike any other.
Detour #19: Nardo Ring, Italy
The are few places in the world where you can legally and safely exceed 200mph. Nardo is one of them.
Detour #18: Col de Turini, France
This is one of the greatest mountain roads in Europe, and whether you’re cranking your pedals or pressing them to the metal, it’s one for the bucket list.
Detour #17: Flüela Pass, Switzerland
When the winter sports crowd (and the economists) have gone then Davos becomes a destination for drivers.
Detour #16: Stelvio Pass, Italy
Top Gear once called the Stelvio Pass the world’s best road. So, if you’ve got a passion for four wheels or two, a pilgrimage is obligatory.
Detour #15: Kancamagus Highway, USA
If there’s a surefire way to fall for New England in the fall, it’s a drive down the Kancamagus Highway.
Detour #14: Black Mountain Pass, Wales, UK
There's a good reason Britain's car magazines and YouTubers head to Wales so often. The Black Mountain Pass over the Brecon Beacons ticks all the necessary boxes.
Detour #13: Grossglockner High Alpine Road, Austria
The engineers who blasted this road out of the Austrian mountainside clearly loved to drive.
Detour #12: Furka Pass, Switzerland
Bond fans will recognise this from the movie Goldfinger, where 007 runs Tilly Masterson off the road.
Detour #11: Britain's Bendiest Road
No sooner have you changed up to third than you have to brake again
Detour #10: Dades Gorge, Morocco
For telegenic twists and turns this road is hard to beat.
Detour #09: Route One, Iceland
Whether you take days or weeks to drive it Iceland’s Route One will be seared on your memory forever.
Detour #08: Atlantic Ocean Road, Norway
Eight bridges span a series of small islands, some so low that you feel you’re skimming the sea, while fishermen catch cod from the side. Others a roller coaster ride into the sky and down again.
Detour #07: California 33, USA
California 33 is a throwback to the 1950s. A time when roads had no guard rails. When the route flowed with the land rather than being blasted through it.
Detour #06: Jebel Hafeet Street, UAE
Few have any reason to visit, except for the pure thrill of the drive.
Detour #05: Col Tizi N’Tichka, Atlas Mountains, Morocco
Climbing to a mighty 2,200 metres the views are either epic or non-existent as the road can get completely engulfed in cloud.
Detour #04: The Rubicon Trail, USA
It’s a rock-crawling, axle-twisting grind through the High Sierras
Detour #03: Alaska Highway, USA
It was a monumental feat of engineering, employing 18,000 men over an astonishingly short eight months, in some of the most inhospitable terrain the world has to offer.
Detour #02: The World's Most Dangerous Road, Bolivia
There are more than a dozen memorials to those who have perished along the way.
