In the off season, I do a decent amount of hiking/ backpacking. My dad, uncle, bro in law and I did a rim to rim hike this spring. We drive to the south rim of the canyon, take a 4.5 hour shuttle ride to the north rim and stay the night at the Old Kaibab Lodge. A shuttle takes us to the trailhead the next morning and we begin a 25 mile hike. Took us a very leisurely 12 hours. This is the second time I've done it. Seeing the Grand Canyon from the touresty south rim doesn't do it justice. It's almost beyond words to describe how massive it is when you're in the belly of it. Started at 0600 at in the mid 40's and by the 3/4 way point, it was mid 90's.
