Excursions into the clubs of Rio for samba competitions and sensual tango performance in Buenos Aires are particularly entertaining ways to spend the evening when your ship overnights in either of those cities. A challenge for hikers is the ascent to the landmark Christo Redentor statue high above Rio; although there is a road, visitors still have steep stairs to climb before being rewarded with a breathtaking view from the top. City sightseeing tours in the major ports are a less taxing way to visit the major highlights. In Buenos Aires, a must-see is La Recoleta, the high-rent cemetery, whose most famous inhabitant is Eva Duarte Peron. Uruguay is South America's cowboy country, and tours are available that spend the day at a working ranch, where city slickers can earn their barbecue lunch by assisting gauchos shear sheep and milk cows. The thrill of a lifetime is a fly-over tour of the Antarctic Peninsula from Punta Arenas, Chile, or the enigmatic Nazca lines from Pisco, Peru. Popular multi-day pre- or post-cruise excursions include the sacred Inca site of Machu Picchu from Santiago, Chile, or one of the world's greatest wonders, Iguazu Falls, from Buenos Aires.
