El Chalten a tiny little town on the edge of the Glacial National Park set up for trekking. You can walk out of the town and into the mountains in little or no time. We did 2 treks to Fitz Roy and to Laguna Torre both about 25km. The landscape is awesome but the town itself is not much to write home about. Still the views more than make up for this. We stayed in Rancho Grande and then Patagonia
