The temperature in Buenos Aires will be pleasantly 20 Celsius. Just perfect for visiting Puerto Medero district or San Telmo. However, you simply mustn’t miss the Parque Nacional Los Glaciares. It is the largest national park in the country with 47 glaciers (!). If we’re talking about top ten must-see in South America, this is it.
