Among the Earth's most dynamic and accessible ice fields, Glaciar Perito Moreno is the stunning centerpiece of the southern sector of Parque Nacional Los Glaciares. Locally referred to as Glaciar Moreno, it measures 30km long, 5km wide and 60m high, but what makes it exceptional in the world of ice is its constant advance - up to 2m per day, causing building-sized icebergs to calve from its face.
In some ways, watching the glacier is a very sedentary park experience, but it manages to nonetheless be thrilling.
