 The primary water source along the River Trail is the Colorado River.If water is to be taken from the river for drinking, it must be either filtered, treated, or boiled before consuming.Due to the proximity to Phantom Ranch and the Bright Angel Campground, hikers who are not in a life-or-death need for water should proceed across the silver suspension bridge past the mule corral, where a water spigot is located near the restroom building before the junction with the South Kaibab Trail and North Kaibab Trail.
