Well, this question does not involve hiking here in the great white north, but here goes....
I am considering taking some time to return to the southwest (Arizona, New Mexico, Nevada, Utah) for a few weeks, sometime soon.
As a very extensive hiker/backpacker/runner in the past, currently still a very frequent hiker/backpacker/walker, I'm interested in hiking in the Grand Canyon area while in Arizon.
Can any of you provide a quick reference as to where to begin some research? I am also looking into hiking down into the Grand Canyon on one of the commonly used trails, and possibly rafting with a commercial rafting service provider.
