6 min de lectura

The Perito Moreno Glacier, a 250-square-kilometer river of ice within Los Glaciares National Park, is one of the world's most famous natural attractions. Autumn, from marzo through mayo, offers what many returning visitors consider the ideal time to experience this geological wonder.

The glacier's massive terminus — 5 kilometers wide and rising 60 meters above the surface of Lago Argentino — is equally spectacular in every season, but otoño adds dimensions that summer cannot match. The surrounding lenga forests, which cover the hillsides of the Magallanes Peninsula where the walkways are located, transform into brilliant shades of crimson and gold. This creates the unique and photogenic combination of blue-white glacier ice framed by fiery follaje otoñal — a visual contrast that defines otoño at Perito Moreno.

Calving events, where massive chunks of ice break from the glacier face and crash into the lake, occur todo el año. Some visitors report that otoño calving can be particularly dramatic as temperature fluctuations between day and night may increase stress on the ice. The thunderous crack and splash of calving ice, echoing across the otherwise quiet paisaje otoñal, is an unforgettable experience.

The walkway system facing the glacier is an engineering marvel, with multiple levels and miradores offering different perspectives on the ice wall. In summer, these walkways can feel crowded, but otoño brings a dramatic reduction in visitor numbers. This means freedom to linger at the best miradores, to sit quietly and listen to the glacier's creaks and groans, and to witness calving events without jostling for position.

The glacier is located 80 kilometers from El Calafate, making it an easy excursión de un día. Glacier trekking options (Big Ice and Mini Trekking) continue into abril, offering the extraordinary experience of walking on the glacier surface itself.
