Turn Right at Machu Pichu is funny and informative story of the history of searches for lost Inca cities, as well as a travel book documenting the authors research trips hiking the Andes. Author Mark Adams writes very well and with great humor, weaving the history of the Inca and Spanish conquistadores, Hiram Bingham's search for the lost Inca cities, and his adventures hiking to the ancient cities of Machu Pichu, Choquequirao, Vitcos, and Vilcabamba (Espiritu Pampa).
