We booked the Canyon X and Upper Antelope Canyon tours. Our guide Robin, was very knowledgeable about the area and history, and very friendly and personable. He pointed out great shots that we would have missed, managed to help us get great shots even in the crowded Upper Antelope Canyon and was flexible in doing things in whatever way worked best for us. There were only 4 of us on the tour and I was able to get some amazing shots of sunbeams in Canyon X. The lunch was excellent too! I would have no hesitation in recommending this tour to anyone.
