Ultimate Antarctica & the Fjords of Southern Chile Buenos Aires - Buenos Aires

Twice-founded and once the wealthiest city in Latin America, Buenos Aires seduces with the world-class acoustics of the Teatro Colón, the ritual theatre of a wood-fire asado at a San Telmo parrilla, and the cobblestoned milongas where tango was born and where it burns still. Cross the estuary to UNESCO-listed Colonia del Sacramento or head south toward the glaciers of Patagonia. As South America's premier cruise hub for Antarctic expeditions and round-the-continent voyages, the city is most inviting from November through March.
