Manali to Leh, India Carved through the Himalayan mountain range, the 500km route through the small towns of Manali and Leh in the Northwest India, is a supreme challenge for bike riders in India and across the globe. The Himalayan range which is blanketed by snow for most time of the year, has accessible roads only for few months. This route of Himalayan Mountains includes roads through pine forests, foothills along with dirt tracks and sealed roads at some points before reaching Leh. This is said to be a tough one despite the fact that it is starkly beautiful.
