The Red Rock Canyon tour is a great option to get away from the Strip for some nature. We've visited other similar areas in St. George and Sedona and still found it worthwhile, particularly with the diversity found there. Just be aware that this will be the highlight of your tour, so take full advantage of your time there. The second part of the tour, the "Seven Magic Mountains," are seven stacks of massive sandstone blocks which have been painted various bright colors. No mountains or magic are involved. They're an art installation along the side of the highway. You will join large groups of people posing in front of the rocks and taking selfies.
Our guide, Denny, did a nice job of educating with interesting facts about the area.
We had a positive experience similar to those reported by other reviewers who went with Denny. He is personable and works hard to make sure everybody's needs are met. The tour vehicle was a newish Ford Expedition and very comfortable. he promised water and snacks were plentiful. Denny was very patient and allowed us to spend as much time at each stop as we wanted.
Denny also cheerfully accommodated the young woman who was part of the other couple in our group by assisting her with what turned into something of a fashion shoot. He actually was able to suggest more attractive poses. He was a magician with their smart phone camera. He is excellent at picking good spots/directions for the best photos. He was persistent about wanting to get us to pose, but accepting of the fact we weren't interested in doing so.
You should be aware that the hours indicated on the summary are approximate. The tour said 8:00am to 2:00pm. We were actually picked up at 7:00am and done by 12:30. The earlier pickup was to allow arrival a the Red Rock Canyon by 8:00am. I'm guessing it was either to avoid crowds or to meet a reserved entry time. In any case, there were no crowds in the canyon. We were fine with the shorter time of the tour because we felt we had as much time as we wanted at both destinations. Larger groups might take longer.
Our one concern is that we weren't able to get a commitment for a pick-up time until about 9:00pm the night before. Denny apparently has to handle all the logistics from his cell phone and has no voicemail set up on his phone. He did return our call, though, because he noticed he had missed a call from out number. He also has email.
