Spits Valley is another chunk of Tibet marooned in India. The scattered villages in this serrated moonscape arrive like mirages, clusters of whitewashed mud-brick homes huddled amid green barley fields below monasteries perched on crags a thousand feet above. The turquoise-grey ribbon of the Spiti River is your near-constant companion, running along a fairly broad valley before turning south at Sumdo into the precipitous gorges of the Hangrang Valley. In many ways Spiti is even more rugged and remote than Ladakh. The Spiti–Kinnaur loop is one of Asia’s great road trips, and a steady stream of motorcyclists, mountain bikers and drivers of all kinds of four-wheelers pit themselves against some of the most challenging roads in India. You will ride an Enfield on ancient Hindustan – Tibet Highway in this ride.
