In a journey rarely, if ever, attempted before, Michael Palin took on the full length of the Himalaya, including the Khyber Pass, the hidden valleys of the Hindu Kush, ancient cities like Peshawar and Lahore, and the mighty peaks of K2, Annapurna and Everest. Facing altitudes as high as 17,500 feet as well as some of the world's deepest gorges, Palin also passed through political flashpoints like Pakistan's remote northwest frontier and terrorist-torn Kashmir.
