Buenos Aires is South America's liveliest and most cosmopolitan city, and we take in the city’s most memorable moments, including the grand architecture of Plaza de Mayo, Recoleta's iconic cemetery and bubbling La Boca. At Iguazu Falls we witness the grand cataract’s mighty power, and if you chose an exhilarating boat trip to the thunderous base of the cascades. From there it’s off to explore Rio de Janeiro, with its sweeping sands, vibrant nightlife and spectacular setting. We take in Sugarloaf Mountain and Christ the Redeemer, as well as having plenty of free time to soak up Rio’s unique atmosphere.
