Located at the southern end of Los Glaciares National Park, El Calafate is a busy seasonal town that is a base to explore the region, in particular the spectacular Perito Moreno Glacier. One of the few glaciers in the world still expanding, Perito Moreno is an astonishing site and one of the highlights of South America. The glacier is over 30km long and 5km wide at its leading edge where it rise to between 60 and 80 metres in height. Inside the park, there are extensive walkways at several levels on the peninsula opposite the glacier's snout to which it advances and often nearly attaches. Here, you can get very close to the wall of ice and regularly hear thunderous cracks as great chunks of the glacier fall off and splash into the water. Other options of experiencing the glacier include boat trips to its base or a glacier walk with crampons and pick-axes.
