I highly recommend Turn Right at Machu Picchu by Mark Adams for anyone traveling to Machu Picchu and especially to those hiking the Inca Trail! The author recreates the original journey Bingham made to the ancient site in the early 1900s. Weaving the history of the exploration itself with that of the ancient Quechua people and with his own journey following the same trail that led Bingham to “discover” Machu Picchu, Adams tells a brilliant story of adventure and culture both past and contemporary along the Inca trails!
