This epic Himalayan highway – the highest motorable highway in the world – is 300 miles long, and takes you from the awe-inspiring monasteries of Leh to the extremist’s paradise of Manali. In this case it is very much about the journey, however; the hairpin bends, streams of icy water from glaciers and hundred-metre sheer drops make it an adrenaline-fuelled ride for motorists and cyclists alike. Lush greenery gives way to arid brown moonscapes and majestic white peaks on the way to the highpoint, the Tanglang La Pass at 5,328 m. Look out for some hilarious and imaginative slow down signs as well.
