Guide complet de Perito Moreno Glacier →

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 mars through mai, 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 automne 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 feuillage automnal — a visual contrast that defines automne at Perito Moreno.

Calving events, where massive chunks of ice break from the glacier face and crash into the lake, occur toute l'année. Some visitors report that automne 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 automne landscape, is an unforgettable experience.

The walkway system facing the glacier is an engineering marvel, with multiple levels and viewpoints offering different perspectives on the ice wall. In summer, these walkways can feel crowded, but automne brings a dramatic reduction in visitor numbers. This means freedom to linger at the best viewpoints, 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 excursion d'une journée. Glacier trekking options (Big Ice and Mini Trekking) continue into avril, offering the extraordinary experience of walking on the glacier surface itself.

Questions Frequentes

Does the glacier look different en automne?

The glacier itself looks the same toute l'année — the massive blue-white ice wall is constant. What changes dramatically is the surrounding landscape: the lenga forests turn crimson and gold, creating a stunning frame that makes automne photos of the glacier uniquely beautiful.

Can I walk on the glacier en automne?

Yes, Big Ice (4 hours on ice) and Mini Trekking (1.5 hours on ice) operate through avril, weather permitting. Book with Hielo y Aventura, the exclusive operator. Automne groups are smaller, making the experience more personal. Crampons and equipment are provided.

Is the glacier still calving en automne?

Yes, calving occurs toute l'année. The glacier is in a constant state of advance, and chunks of ice break off regularly. There's no seasonal pattern to calving frequency. Be patient at the walkways — most visitors witness at least small calving events during a several-hour visit.

How early should I arrive at the glacier?

En automne, arrive by mid-morning to maximize your time before the shorter daylight fades. Departing El Calafate by 8-9am allows a full day at the glacier. The drive takes about 1.5 hours. Early arrival also means the best morning light for photographie.
