Our tour guide, Lori, was fantastic. She was very knowledgeable and helped us with taking pictures. She knew just the right place for us to stand to get the best shots. She also took a couple pictures of us. She was a whiz with using cameras. Our tour was at 7:30 am, so it was not too hot, but the lighting is provably better a little later in the day, when the sun is directly above. It was an amazing tour and we highly recommend it as an Arizona must-see attraction.
