I've travelled all over the USA — almost nobody has been to this place where 'no roads lead'

The landscapes of the USA are remarkable. From the California deserts to the snowy mountains of the Rockies, and from the beaches of Florida to the flat and windswept plains of the midwest, the variety is astonishing and visiting each place can be like going to an altogether different country. The USA is the third most-visited country in the world, behind Spain and France, taking in around 67 million tourists each year.

And of these visitors, most head to New York, followed by Florida, California, Hawaii and Nevada (home, of course, to Las Vegas). Compared to those numbers, almost no one goes to the USA's least-visited state, Alaska. Alaska is both the biggest state and the least densely populated.

You could fit the entire UK into it seven times, yet its population is only around 730,000 (about the same as the wider Sheffield urban area) so there are vast parts of its mountain peaks, huge forests and glacial landscapes where you won't see another soul. But even within Alaska, there are different levels of remote. For example, around 290,000 people live in its largest city, Anchorage, where there's an international airport and pretty much any modern convenience and chain store brand you'd expect to find in any American city of comparable size.

The ocean waters around Alaska's southernmost coast, meanwhile, are popular cruise destinations, thanks to the stunning scenery and wildlife on show, from humpback whales to Orcas, and sea lions to otters. Further inland, Alaska is home .
