(3686 x 5943) Ribbon Falls is a true gem of the North Kaibab Trail. The waterfall is located in a grotto on the west side of Bright Angel Creek, so reaching it is a short but extremely rewarding side trip. Hikers caught in the heat of the day should consider taking a siesta here from 10 a.m. to 4 p.m. NPS photo by Michael Quinn.

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 the hotter months, which can begin as early as May and last through September, it is critical that hikers have the discipline to begin their hike well before dawn or after 3 p.m. Success and enjoyment really depends on the amount of time spent in the Plan Ahead and Prepare stage (Leave No Trace). Success in the summer can be as simple as staying off the trail and out of the sun between 10 a.m. and 4 p.m. Hiking the entire North Kaibab Trail in a single day is not recommended, particularly in summer, as it is nearly impossible to avoid hiking in the heat of the day. During the deep winter months, the upper section of trail in Roaring Springs Canyon can be ice-covered and perpetually snowbound. On the North Rim, hikers need to be prepared for extreme winter conditions.
