For both ultrarunners and hikers, the Grand Canyon is considered by most, one of the greatest destinations to experience. Thousands make their pilgrimages each year to experience the joy of journeying across the Canyon's great expanse, rim-to-rim. Crossing the Canyon and returning back is an activity that has taken place for more than 125 years. Native Americans crossed the Canyon centuries earlier.

During the spring and fall, each day people cross the famous canyon and many of them, return the same day, experiencing what has been called for decades as a “double crossing,” and in more recent years, a "rim-to-rim-to-rim." Anyone who descends into the Canyon should take some time learning about the history of the trails they use. This article tells the story of many of these early crossings and includes the creation of the trails, bridges, Phantom Ranch, and the water pipeline, the things you will see along your journey.
