I'm going on a run in October with my old Phoenix East Valley group to Canyon De Chelly and it's one that we had to reserve in advance and pay Navajo tour guides who will be riding along with us and camping with us for a couple nights. We're going to be in 3 groups of 5 jeeps and we're already booked up. I voted for it on here since it looks to be the most scenic of the places but again probably the most pricey since you'd have to pay the guides I think.

Here's some photos of runs through Canyon De Chelly:

I've been told that the run through there is one you'll never forget!

 

Most of the trails in Sedona should not be a problem for a stock JK, however, I will run all the trails before the run to make sure to call out any concerns on a particular trail so someone can choose to do a different trail at that time.
