I took this tour with my 12 and 14 year olds and am very glad we did. It gave us so much more information and appreciation for what we were seeing than if we had just driven around ourselves. Our guide, Keaton, picked us and others up from our hotel in Flagstaff for a full day’s tour. At various points, he talked about the Native American history in the region, the early European explorers, the more modern history and how it fit into the National Park system. He also sat us down for a lesson in the geology of how the canyon was formed, complete with handouts and rock samples, and also talked about the animals and plants in the area. He was great at answering questions. I will recommend this tour to anyone visiting.
