Buenos Aires, Argentina's capital on the Rio de la Plata, is a big, European-feeling city of grand avenues, cafes and late nights, and the birthplace of tango. Plaza de Mayo, ringed by the pink Casa Rosada and the Metropolitan Cathedral, is the political heart. Cobbled San Telmo has antique shops and a Sunday street fair, and La Boca's brightly painted Caminito recalls the immigrant dock workers and the painter Benito Quinquela Martin, who gives the cruise terminal its name.
Recoleta's cemetery holds Eva Peron's tomb among ornate mausoleums, while Palermo offers parks, museums and restaurants. The port is a major embarkation point for South America and Antarctica-bound itineraries, with many ships overnighting, which leaves time for a steak dinner and a tango show.
