At the southern tip of the South American continent is a region unlike anywhere else on earth. Comprising parts of Chile and Argentina, Patagonia is named after the native people first identified by Magellan in 1520. To the west and south, there are Andean peaks, whilst to the east are vast steppe-like plains covering several entire Argentinian provinces. There are a number of standout geographical features that ensure Patagonia's popularity for adventure travellers. Largely within Chile, in the west of the region, the remnant Patagonian Ice Sheet is the world's 3rd largest (after Antarctica and Greenland). Glaciers flow out from this ice sheet and have sculpted some of the world's most dramatic rock spires, notably the Torres del Paine (Chile) and Cerro Torre and Cerro Fitz Roy in Argentina's Los Glaciares National Park. There are excellent possibilities for trekking here, either day-hiking from comfortable Eco-Camps to the finest viewpoints, or making a continuous trek, such as the Paine Circuit. The Perito Moreno Glacier, dropping icebergs into its icy lagoon, is another outstanding highlight of this rugged 'Land of the Tempest'.
