Founded in 1927 as a frontier town, El Calafate is the base for excursions to the Parque Nacional Los Glaciares, which was created in 1937 as a showcase for one of South America's most spectacular sights, the Glaciar Perito Moreno. Because it's on the southern shore of Lago Argentino, the town enjoys a microclimate much milder than the rest of southern Patagonia.
To call El Calafate a boomtown would be a gross understatement. In the first decade of this millennium the town's population exploded from 4,000 to more than 25,000, and it shows no signs of slowing down; at every turn you'll see new construction, with many luxury and boutique hotels cropping up. As a result, the downtown has a new sheen to it, although most buildings are constructed of wood, with a rustic aesthetic that respects the majestic natural environment. One exception is the casino in the heart of downtown, the facade of which seems to mock the face of the Glaciar Perito Moreno. Farther out of the city is another glacier lookalike, the brand new Glaciarium museum, architecturally modeled on Perito Moreno and with Argentina's only ice bar.
Now with a paved road between El Calafate and the glacier, the visitors continue to flock in to see the creaking ice sculptures. These visitors include luxury-package tourists bound for handsome estancias in the park surroundings, backpackers over from Chile's Parque Nacional Torres del Paine, and porteños (from Buenes Aires) in town for a long weekend.
