We had an outstanding experience with our day trip to the Grand Canyon. Diana, our fabulous guide, was extremely knowledgeable and well-organized. She tailored the tour to our groupās interests, and she gave us historical and geological information throughout the trip. The stops utilized for viewing the Canyon are selected so that one can understand the path of the river and manner in which the Canyon was formed, which was extremely helpful to us. We loved this trip and are looking forward to taking another one with Arizona Scenic Tours next year when we return to the Phoenix area. When presented with the options for lunch, be sure to select El Tovar, as the food and service was great, and the historic hotel is fabulous to see. Also, do not miss the Harvey exhibit in the neighboring Bright Angel lodge to fully appreciate the impact the Sante Fe and Fred Harvey organization had on the development of tourism in this area.
