Grand Canyon is, above all else, a place of extremes. It is necessary to take appropriate precautions depending on seasonal variations in trail conditions. During winter months, the series of tight switchbacks near the top of the South Kaibab Trail will be icy for days or even weeks after a snowstorm. For hikers who insist on entering the canyon from May to September, it is critical to begin hiking well before dawn or in the late afternoon: Success depends upon staying off the trail between 10 in the morning and 3 in the afternoon (average descent time is 4 to 6 hours). Failure to arrive at Bright Angel Campground by 10 in the morning during hot weather can result in ill health or even death; at the very least, it will be a miserable experience. Ascending the South Kaibab Trail in hot weather is not recommended. Carefully study the National Park Service "Hike Smart" pamphlet issued with summer permits and always practice Leave No Trace.
