Machu Picchu. I respect the Incas for building it, the real issue I have with it is the current management. It’s flooded with people (they let in over 3x the cap sto make money) being annoying and it’s very expensive, they bus people up a huge hill all day and we are required to have a tour guide and only spend 3 mins at certain areas. It’s misrepresenting the history of the Incas to people with selfie sticks. Not my fave
You are WAY better off seeing the Inca capitol, Cusco because it’s where they actually lived and thrived. See Sasqsyhuaman and the Qoricancha sun temple. Go on a backpacking trip and you will find Inca and pre Inca stuff Everywhere. With no idiotic tourists families. I highly recommend it.
¡Viva Perú!
