Thanks Bret, Do they all require quided tours for the most part (well at least except for the aforementioned one in Monument Valley)? Wait a minute, you said Antelope Canyon! Isn't that in AZ near Page? Or is there another one in Utah?
Antelope Canyon is in Arizona. Actually, so is part of Monument Valley. You asked what what else was on the rez so I mentioned a few of the popular ones in this general area.
Yes, all of those locations require guided tours. You *might* be able to photograph from the rim of Canyon de Chelly without a guide but I can't confirm that as I've not tried it. Best to call ahead for information. The Natives don't take very kindly to folks not following their rules.
