El Calafate is like a ski town in the middle of nowhere. The obvious attraction is the glacier, but I like renting a car and driving to the some of the out-of-the-way spots for a picnic or just to hike around a bit. We were there for Christmas Eve and it was kind of hilarious. We had a special holiday dinner in a Chinese Buffet that had stuffed animals spread around. It looked like a cross between a saloon from the wild west and a nail salon in china town. Good fun though and the the little town even surprised us with a small fireworks display.
Of the three glacier fields I saw in Argentina, this is the smallest but best for viewing.
El Calafate is a cute little town. There are plenty of cafes and bars to check out. You can book any tour from your hostel and people are really friendly!
The starting point for a visit to the mountains and glaciers on the border with Chili. From here you visit the vast ice mass that is the Perito Moreno glacier and the deserted, wild and beautiful mountain area around Cerro Torre.
