El Chaltén is a very young town founded in 1985. Its at the North of Lago Viedma and 210 kilometers from El Calafate, at Los Glaciares National Park.
The main attractions are the Mount Fitz Roy, Cerro Torre and the Southern Ice Field.
The town has about 1500 permanent inhabitants, its small but you will find it quite developed, due to a high demand of visitors during the summer season ( october to march). During the winter, the services are reduced: 1 daily bus between Calafate and Chaltén, 2 or 3 restaurants and a few Hotels will stay open.
There are also supermarkets, gas station and ATM. By the way, it´s always good to have some pocket money, because the ATM might not work and not many places will accept credit cards.
