I booked a tour for four people by phone approximately 3 weeks in advance. When we showed up at the little booth in Sedona on the day of our tour, the woman there, whose voice I recognized as having been the one who took my reservation, said they had no record of the reservation! Fortunately she was able to get one of their guides to come in and take us out. That part of the experience, the most important one of course, was amazing! I think the tour we took was called the 'Rough Rider Canyon Tour'. We went to out of the way places with an excellent guide, named Larry, who stopped a lot for photos and we got some amazing shots at sunset on our return. Larry was very knowledgeable about the area and wildlife, sociable, interesting to talk to, and gave us a great overall experience. It was obvious he cared about the environment. This tour company is highly recommended!! I know it can happen anywhere, but just to be safe be sure you confirm your reservation prior to showing up so you're not faced with an unpleasant surprise. We were lucky Larry could come right away to take us out, but that may not always be the case. Because of the mishap, I gave this company 4/5 stars.
