South America offers rugged mountains, white-sand beaches, slow-moving jungle rivers and electric-blue glaciers - and we haven't even gotten to the cities yet. Rio de Janiero, Brazil's capital city wedged between blue ocean and mountain peaks; Buenos Aires, the historic and stylish capital of Argentina; Santiago, Chile's great city set against the Andes Mountains. If it's too hard to choose just one South American destination, we understand - you'll find tours roving all over this amazing and diverse continent. Or go beyond its southern reaches, and sail all the way to Antarctica.
