When you see Cliff Palace in person, it is so much larger than it appears in the photos. I would suggest that you take photos with people in them to show the scale. It is unbelievable that we can still view these structures that were built so long ago and we can see how these people lived. I could not imagine living there and scaling the walls in the manner they did. Because of the altitude, we just took our time and was able to climb in and out of there with no issues. It's only $3 to take a full tour with the Park Ranger.
