The Corridor Trails by Ken McNamara and Rob Kleine. This video will help you prepare to hike the Grand Canyon backcountry. This is the Grand Canyon trail guide I turn to most often. Anyone someone asks me a Grand Canyon question I can't answer off the top of my head, this is the book I pull from the shelf.
Trail descriptions leave a lot to the imagination and are a bit dated, but useful nonetheless.
Her mix of personal reactions, history, and folklore makes an enticing read. Lots of books detail the trails of the Grand Canyon. This books provides a sense of what it feels like to backpack the Grand Canyon's trails. I first read this book many years ago, while in high school. It is rare for me to read a title more than once, yet.
