In Peru's southern desert is one of the world’s greatest enigmas - the Nazca Lines.
Etched into the desert floor there are mysterious designs and drawings so vast that you can only really appreciate them from the air. Designs include a spider, hummingbird, monkey and whale.
Decades of archaeological study and supposition have thrown up any number of explanations for the Nazca Lines, from alien intervention to man-made astronomical charts or maps of water courses. Some of the explanations are more scientific and more plausible than others, but none have provided a definitive answer to the puzzle - why would an ancient civilization without the means of flight create something that can only be seen from the air? See for yourself and draw your own conclusions. Quite apart from the lines, the Nazcan civilizations have left a legacy of arts and archaeological sites. An overflight of the Nazca Lines can be combined with a visit to the Paracas National Reserve and a boat trip to the Ballestas Islands.
