Deep in the Peruvian desert lie these mysterious geoglyphs that have confounded geologists and tourists for ages! They have withstood famines, floods, earthquakes, and so many kinds of natural disasters and remained unchanged through the centuries. This adds to the enigma of the lines. Despite many conjectures, no body really knows why or how the Nazca lines came to be. Some historians insist they are part of an elaborate astrological system made by Incans while others insist they are part of an agricultural matrix. There are also theories that insist they are a result of alien activity.

Today, lots of tourists plan a weekend getaway from Cusco or Lima specially to see this enigmatic natural phenomenon for themselves. The lines are deeply etched into desert sand but the figures are so huge that it is only possible to view them from a height. As a result, small aircraft tours are the only way to actually see the Nazca Lines. The Nazca airport is located in the middle of the desert and is a well-oiled operation. Flights leave every 10 minutes and tourists get to see the lines in all their glory. Expect to see geometrical figures such as triangles and trapezoids, animals, plants, and human figures such as an astronaut. The more one sees of the lines, the more mysterious they seem!
