Down the southern half of South America, Argentina reaches from the subtropical Iguazu Falls to the Andes and the windswept plains of Patagonia. Buenos Aires, the wine country around Mendoza and the Perito Moreno glacier are among the best-known stops, with Tierra del Fuego at the far south. Spring and autumn are mild and comfortable in the central regions, Patagonia is best from November to March, and the far south is cold and quiet in winter.
