Nazca Lines

The Nazca Lines are the most enigmatic ancient geoglyphs on Earth, covering 450 square kilometres with figures up to 370 metres long, etched between 500 BC and 500 AD. Unlike conventional archaeological sites, they can only be fully appreciated from the air — making a light aircraft tour the definitive experience. The UNESCO World Heritage site includes a metal viewing tower for three figures, but overflights reveal the full scope, including the spider, hummingbird, and monkey shapes. Per flight, viewing these lines costs around $80, which is 50% cheaper than the average helicopter tour to Machu Picchu. The purpose remains a mystery, but the precision and scale surpass comparable geoglyphs elsewhere, with straight lines extending over 50 kilometres across the desert.
