In the Andes, sublime, almost mystical trains run, crossing the mountains and descending to the Pacific. There are few places in the world like this, places whose immensity, isolation, and mystery make you want to see further, to travel again and again. Philippe Gougler begins his journey through the Andes by Lake Titicaca and a train like no other: a rail bus. The journey continues to the heart of the largest salt desert in the world: the Salar de Uyuni. Then, head to Chile and the Pacific coast aboard one of the freight trains that cross the Andes and travel through unique settings.
