Nanga Parbat Pilgrimage is a classic of mountaineering literature that has inspired thousands of climbers. In it, Buhl records his 1953 solo first ascent of Nanga Parbat - the ninth-highest mountain in the world, and the third 8,000-metre peak to be climbed, following Annapurna and Everest. It was one of the most incredible climbs ever made.
