For once, here's a glacier that doesn't herald the apocalypse. While Argentina's Perito Moreno Glacier may appear to be just a big (97 square miles!) chunk of frozen water, it's actually one of the world's few ice masses that is still growing. Of the 48 glaciers fed by the Southern Patagonian ice field, Perito Moreno is one of three that has skirted the effects of global warming and continues to expand today.
The Perito Moreno Glacier draws travelers from all over the world to Los Glaciares National Park, in the southwest province of Santa Cruz. Tourists and adventure-seekers come to simply see the beautiful frozen wonderland, and some even dare to traverse the icy terrain.
How to get there: Travelers can fly to El Calafate Airport via Buenos Aires. From there, Los Glaciares National Park can be reached in less than two hours by bus or taxi. Many companies also offer bus services from local hotels to the park. General admission to the park is $25 USD.
What to do: There's a large visitor's center at the glacier, as well as a walking circuit that allows tourists to see the southern part and the east-facing edge of the glacier. Tour companies also offer boat excursions to see the north face of the glacier, too. For those who want to do more than spectate, join a trekking tour on the ice.
