We picked this trail for our hike out of the canyon since it wasn't as steep as the way we took down and also because it would show us a different part of the canyon. (The South Rim shuttle service would take us back to the car once we got back up to the rim.)
Hiking out of the canyon is much harder than the hike down. Besides the obvious, uphill requires lots more energy than downhill, you also lose the energy boosting experience of the canyon's amazing views.
Weighted down with a heavy pack, the hike back up tends to focus your gaze on your shoetops as you plod up switchback after switchback. This is where you really pay the penalty for every extra ounce of gear you've elected to take along.
Stop frequently to pace yourself. When you do dtop, turn around and look back into the canyon for more of those amazing views. This hike takes you through a lusher, greener part of the canyon than the South Kaibab trail does and there's lots to see here.
Just like the South Kaibab, this is a well maintained trail. Both trails are wide enough that there's no sensation of vertigo, so even hikers with a modest fear of heights will generally feel safe, especially since most of the trail is carved against one side of the canyon wall.
If you have the time and the physical ability, this hike can be one of the most memorable experiences of your life!
