As a destination for active travellers, Patagonia is nothing short of iconic. The very best way to do this South American region justice is to hike all over it. Trek through the crisp air of El Chaltén (with its crazy beautiful Cerro Torre mountain) and then to the area near the imposing Perito Moreno Glacier. In between, marvel at the giant sky, vast views, and big city appeal of Buenos Aires while you revel in a sense of personal triumph. Patagonia's ready and waiting for you. Hotels (8 nts).
