This is the outfitter, they also do rides in Bryce and Zion:

There is a separate concessionaire for the south rim (and I see they also have an above the rim ride):

Saddleup, yes, I have many more, but you’re a glutton for punishment! Here is another album I had already uploaded that has other views of Grand Canyon plus a few of Glen Canyon (boat trip) and some big horns in Zion (passed through on way home)- I will look over the weekend and see what else I had from the mule ride: https://picasaweb.google.com/100310658467918237790/GrandCanyonEtcOct2012?authkey=Gv1sRgCPep3vS-3rv1dg
But as has been noted, pictures just can’t do any of these places justice- Grand Canyon just has to be seen in person, even if you don’t ride the mules, it will just blow you away.
FatDinah,you are right, the pack mules require a higher level of expertise, smarts, etc. Ironically, my understanding when the ‘Grand Canyon’ mules are retired/ rehomed is that the pack mules are harder to place while there are waiting lists for ‘favorite riding mules.’ Which is a shame (but shhh, my little secret for when I have room for a mule) because many of these mules have years of use left on gentler terrain and they sure have desirable experience and mileage.
By the way, we think we horse people are nuts- wait til you encounter the folks who RUN from top of south rim, across canyon, to top of north rim, and back, IN THE SAME DAY. I do have a rim to rim hike on my to do list but I do believe camping along the way will be MUCH more civilized.
