The best time to visit Fitz Roy for trekking and outdoor activities is during the austral summer, from November to April.
This period offers the most favourable weather conditions, with longer daylight hours and generally higher temperatures, making it ideal for exploring the trails around Mount Fitz Roy and Cerro Torre. While you might still encounter some changeable weather, this window provides the best chance for clear skies and comfortable hiking. Many of the local businesses and services are fully operational during these months.
For those who prefer slightly fewer crowds and are prepared for cooler temperatures, the shoulder seasons of November and April can be a good option. The autumn colours in April can be particularly striking, adding a different kind of beauty to the landscape. However, some trails or facilities might start to close or have reduced hours towards the very end of April.
If you're interested in winter sports like cross-country skiing or snowshoeing, June to September is the winter season. Expect cold temperatures, significant snowfall, and shorter daylight hours. Many trekking routes will be inaccessible or require specialist equipment and guides.
