Calafate is a small tourist town in southern Patagonia Argentina and Perito Moreno is a glacier with easy access to see it calving whether on land or by boat.

Within Los Glaciares National Park, 82 km from the town of El Calafate, Perito Moreno Glacier appears immense and majestic before the amazed eyes of the visitors. It is one of the few glaciers in the world which is in constant advance and growth. Its front is 5 km wide and its height reaches 80 meters above sea level.

The glacier and its surroundings officially became Perito Moreno National Park in 1937, with the aim of protecting the lenga forests and two important lake systems that include glaciers, waterfalls and a portion of the Patagonian steppe.

Ice blocks of different sizes continually detach from Perito Moreno glacier and fall into the waters of Lake Argentino, causing spine-chilling sounds and amazing waves on the surface that make of this view an unforgettable sight. Once in the lake, these ice floes, which may vary from white to sapphire blue tonality, are left adrift until they completely melt.
Although everything seems static and immovable, the erosion caused by the force of the detachment continuously models the shape of the mountains. The joint action of cold weather, the sun and the wind, as well as gravity, constantly modify this impressive landscape.
