Argentina is a country of extremes done with style: Buenos Aires' tango, steakhouses, and Belle Époque avenues; Iguazú Falls' 275 cascades in subtropical jungle; Mendoza's Malbec vineyards under the Andes; and Patagonia's glaciers, granite towers, and steppe stretching to the end of the world.
Distances are continental — Buenos Aires to Patagonia is a 3.5-hour flight — so trips are built from two or three regions. The classic first trip: Buenos Aires (3 nights), Iguazú (2), and Mendoza or Patagonia (3–4).
Seasons are reversed from the US: Patagonia is a November–March destination (their summer), while Buenos Aires, Iguazú, and Mendoza are good almost year-round. January–February is hot in the north; July is for Bariloche skiing.
Argentina suits food and wine lovers, tango romantics, hikers (Patagonia is world-class), and anyone who wants South America with European polish. The exchange rate has long made it one of the world's great travel values.
