During the fall, Patagonia is dressed in warm colors and is one of the most beautiful times of the year to explore its diverse ecosystems. From the Nothofagus forests to the arid steppes, the region is home to rich biodiversity, with its flora, fauna and fungi species adapting in unique ways to the season, which runs from mid-March to mid-June in the Southern Hemisphere.

Fall in Patagonia is an incredible time of year to experience Patagonia’s natural weath. The forests are a symphony of colors, and birds such as the bandurria and the Chilean flamingo are a spectacular sight as they make their migratory journeys north. Meantime, other wildlife like the puma increasingly appear as they come down from the mountains.
The changing of the seasons invites us to contemplate and be enchanted in other ways by the Patagonian landscapes, rediscovering or revisiting places where the autumn climate produces impressive transformations in the landscape. Here are six destinations or national parks to consider visiting this time of year.
ADVENTURE DESTINATIONS IN ARGENTINE PATAGONIA
El Chaltén
Located in Santa Cruz province, in southwestern Argentina, El Chaltén is an iconic destination known as the trekking capital of Argentina due to its impressive mountainous landscapes and outstanding hiking trails. The area is part of Los Glaciares National Park, home to Lake Viedma, one of the longest lakes in the country, several glaciers, such as Perito Moreno and Spegazzini, and the stunningly beautiful Laguna de Los Tres. The region is most famous thought for its iconic mountain, Mount Fitz Roy, also known as Cerro Chalten, which rises to 3,405 meters above sea level.
In autumn, the forests are painted in warm colors, offering a magnificent show, and revealing species of fungi such as the tongue of cow (Fistulina antarctica) and the forest gum (Heterotextus alpinus).
