Trans-Siberian Highway

Far less easy going than the Trans-Siberian Railway, this is one of the longest and toughest roads on the planet. It’s no surprise a road stretching from the gates of Europe to the Pacific Ocean will give you some difficulties either, only the heartiest vehicles and their drivers can survive along the road which winds along the southern borders of Russia. It traverses several mountain ranges, and passes through desert, marshland, and forests, crossing the length of Asia in the process before finally arriving in Vladivostok, merely a few hundred miles from the border with North Korea and Japan.
