Our tour guide, Neil, did a great job of explaining the geological aspects of this incredible landscape. He was knowledgeable (studied geology) to an extent I could not have anticipated on this type of excursion. The terrain was modest, and most could fully enjoy all aspects of the trip. The last piece was a climb through a slot canyon. My elderly parent was able to do it, but those with moderate physical limitations might not be able to. Overall, a great trip!!
