Our tour guide promptly picked us up in Flagstaff, AZ. He was knowledgeable about the area, always ready with stories! The tour around the South Rim was great, but my favorite was the "secret spot" as others have mentioned. We took the best panoramic picture of our small group at that spot! We all felt it was a thorough, worthwhile tour. Great investment for anyone's first visit who isn't sure where to start.
