Not knowing much about the Grand Canyon and having just 1 day, this tour was the perfect answer. Our guide, Keaton, was super. With his degreed background in biology and American history and knowledge of geology, he kept us informed about the geological and natural history of the Canyon. The company prepared fantastic handouts and at one view point, Keaton had portable chairs all set up and gave our group a detailed geological explanation of how Grand Canyon formed, complete with rock samples. Finally, the value of the tour is that he knows the view points that are less crowded. All in all it was well worth the price. A full day of fun and knowledge. Thank you Keaton.
