While Macchu Pichu is the more obvious attraction in Peru (and rightly so), I’ve always leaned toward forgoing the trek to the city in the clouds for an actual flight above the World Heritage-listed rectangles, triangles and swirls. And no, my fascination with this site does not involve a belief in the popular lore that these shapes somehow relate to alien life. I think it’s more amazing that human beings were able to accomplish this extraordinary feat.
