Be part of the mystery and visit the Nazca Lines, an enormous network of lines and drawings of animals and plants, attributed to the Nazca culture, covering an area of approximately 350 km2. Some of the best drawings depict humming birds, dogs, monkeys and "chaucato", long-tailed mockingbirds. From a 12-metre high viewpoint, the figures of the hand and the tree can be partially seen. However, to fully appreciate the drawings, the area must be flown over in a light aircraft. The Nazca Lines were declared a World Heritage Site in 1994.
