Local Info & Media
Peru is such a visually stunning place that it’s easy to find photos and blogs. However, for in depth books about the history and culture, it’s difficult to find much in English.
Peruvian author María Rostworowski has written some thorough and exhaustively researched books. I highly recommend History of the Inca Realm.
A fun book about Machu Picchu, in English is Turn Right at Machu Picchu by Mark Adams.
My website has a lot of information about specific treks, places to visit and restaurant reviews.
