At the southern tip of the Andes, Perito Moreno forms part of the Southern Patagonian Ice Field - the world's third largest reserve of fresh water. The glacier often comes out top in voters lists of the world's most spectacular glaciers.
Walking on the ice can be arranged via any number of operators in El Calafate but my trip was with
Hielo & Aventura. Their mini-trek gives around 1.5hrs hiking in crampons, with a much enjoyed glass of whisky on glacial ice at the end!
