Here are some great books to read before or after your Copper Canyon trip:
In the Sierra Madre, Jeff Biggers–a great book about life in the village of Cusarare near Creel. History, Tarahumara culture and canyon lore fill this valuable book
Mexican Spanish, Lonely Planet Phrasebooks–This little book will get you there. Good for local terms and expressions.
Tarahumara: Where Night is the Day of the Moon, Bernard Fontana–This book includes tons of info on ways of the Raramuri as well as photos.
Born to Run– This well written bestseller by Chris McDougall tells the story of the barefoot running Tarahumara and especially for people on our Copper Canyon Running Tour is a must read. It may be a bit sensational and perhaps miss the essence of Raramuri culture at spots, but it is well done and a great resource.
