AMAZING hike! We started at the North Kaibab trailhead around 3:45am and arrived at Phantom Ranch just before 10am. Stayed two nights in the dorms at Phantom and then hiked up Bright Angel at 3am to avoid the August heat in the sun and arrived at the South Rim just before 11am. Plenty of water sources along the way, but they’re unpredictable, so check with the rangers on which sources are running before you leave!
