As we all know, the mountaineering world has turned its attention to Pakistan and the Karakoram mountains. For the next month and a half, it will be home to some of the most difficult expeditions taking place at the moment, with climbers attempting K2, Broad Peak, Nanga Parbat, and others. So what exactly does this place look like? The video below – narrated by David Attenborough no less – will provide a clue. Like the Himalaya, these peaks are tall, rugged, and jagged, and can put fear and doubt into the heart of a climber just by looking at them. They are also beautiful and fascinating, with a siren song that can’t be ignored either.
