Argentina is big enough to hold a city break, a jungle waterfall and a glacier in one fortnight. Buenos Aires is late dinners, steak and tango. Iguazú, on the border with Brazil, is nearly three kilometres of falls in subtropical forest. Far to the south, Los Glaciares is ice fields, peaks and milky lakes.
It suits couples and families who like to walk and eat well. We join the pieces with domestic flights of two or three hours, and give each place enough nights to settle in. Wine lovers add Mendoza; wildlife lovers add Península Valdés for whales.
The honest caveat is distance and weather in the south. Patagonia is windy, changeable and mostly closed to walkers in winter, and flights between regions often route back through Buenos Aires.
