The best time to visit El Chalten as part of your Argentina vacation
is between September and April. The most popular time to go is between December and February which is summer and the high season. The weather is extremely unpredictable in Patagonia, no matter what season you travel in. You should expect to experience four seasons in a day! It gets a bit cooler in March and April but this can be a lovely time to visit to see the Autumn colours in the trees. Spring (September and October) are also nice months to visit for less crowds. Most hotels close between May and August for the winter.
