Patagonia has a whole host of show-stopping natural attractions, but chief among them is surely the Perito Moreno Glacier.
Still advancing by the day, the 18-mile long, three-mile wide torrent of ice can be witnessed from close up, where its mammoth dimensions become clear. The cliff-like faces of the glacier calve regularly, sending huge blocks of ice thundering noisily into the waters of Lake Argentino.
A range of viewing platforms stand nearby, while boats regularly take to the water to give tourists an alternative perspective. Those who want to take the experience further can arrange trekking tours on the glacier itself.
It's a major tourist draw, thanks in large part to a location close to the city of El Calafate, although the glacier itself is one of more than 200 in Patagonia's Los Glaciares National Park - and one of just three that aren't retreating. The pressure and build-up caused by its advancement results in an enormous 'rupture' of breaking ice approximately once every four years.
