The Perito Moreno Glacier, located 78 kilometres (48 mi) from El Calafate (map). El Calafate has grown due to the tourist influx into Patagonia. It is set on the glacial blue Lago Argentina and is full of eager trekkers.
Due to its size and accessibility, Perito Moreno is one of the major tourist attractions in southern Patagonia and the rupture of this glacier is considered one of the most impressive natural spectacles in the world.
The glacier advances between June and December and recedes between December and April. The formation of an ice barrier is a complex process, since there is a feedback mechanism between the glacier and the lake, which affects the oscillations of the position of the glacial front in a fairly stable way.
Food is expensive mainly due to the remote location of the city. There are several supermarkets in town, including a big one (“Anonyma”) at the Eastern end of the main street, with fair prices. It remains open at least until 9PM (except on Sunday). Buy your food for your tours in advance, because on ruta 40 and in the glacier national park there are almost no places to buy food.
