Route: South Kaibab Rim to CO River to South Bright Angel Rim - [Grand Canyon]

Grand Canyon.

From South Kaibab down across the CO River to Phantom Ranch, then back up the South Bright Angel trail to the South Rim.

To start this run at the pre-dawn hours, watch the sun rise over the Canyon walls, is spiritual.  Only can be described and felt as someone who has been down there in person.
