Perito Moreno Glacier, Argentina
Patagonia's Perito Moreno Glacier is deservedly one of Argentina's most popular attractions.
Perito Moreno, an advancing glacier in the heart of Southern Patagonia, is a UNESCO World Heritage site and one of Argentina's most popular attractions. There seems to have a whole other sense of scale in Patagonia, and Glaciar Perito Moreno is a prime example. It's one of the largest glaciers not only in Los Glaciares National Park but in South America, with a wall of over 200 vertical feet or roughly the size of a 15-story building that goes back 3 miles. Of course, part of the beauty of the glacier is that it's constantly changing and unlike just about every other glacier in the world, this one is swelling and growing steadily - rather than receding - at a rate of up to 7 feet a day, not counting the massive chunks of ice that fall off the façade into the Canal de los Tempanos as well.
There are lots of ways to get closer to this natural wonder including guided glacier trekking tours and glacier viewing cruises on Lake Argentina. The glacier is located within Los Glaciares National Park about an hour and a half drive from El Calafate.
