Our Nazca tours take you to this southern Peruvian desert town, where you are sure to be left pondering the meaning of the Nazca Lines, the centuries old lines etched into the pampas sands. The Nazca lines are not simply a series of parallel lines, but images, some of which have a span of up to 300m, such as whales, monkeys, birds and trees. The true reason for the giant geoglyphs remains a mystery, though theories range from the lines having acted as astronomical calendars to offerings to the pagan gods and theories of the extraterrestrial. On South America Adventure Travel's Nazca tours you will be sure of a sunny day as the sun blazes all year round with the evenings clear and crisp. Nearby city Cerro Blanco lays claim to having the highest sand dune in the world, making it a popular spot for adventure sports such as sandboarding. SAAT's Nazca tours can also include a day trip to the city of Nazca, which is home to two important museums on the ancient Nazca culture.
