Rugged, snow-capped mountains stand imposingly amid the wild south of Argentina and Chile, fringed by huge icy lakes and windswept grasslands. In the distance shy guanacos roam and a few hardy gauchos tend their many sheep. We discover the sheer-sided peak of Mount Fitzroy and the immense Perito Moreno Glacier, where chunks of ice are often seen cracking into the water. Our journey culminates in Ushuaia - the most southerly city in the world. Renowned for world class trekking and outdoor activities, the raw natural beauty of Patagonia never fails to astound.
