Due to our schedule for the day, we arrived late morning and were on-site through the middle of the day which wouldn't have been my first pick as a photographer. It was a bright but overcast day which filtered some of the harshness and it didn't photograph too badly considering. My preference would be earlier in the morning but due to the opening hours there isn't an option for sunrise or dusk, I have seen those photos but they must be either special events or their own photographers. Conversely, the afternoon is less busy so taking wider photos down through the site without stragglers from other groups getting in the shot would be easier but the site is well designed in flow and where the tour groups stop so that you are rarely aware of the group ahead or behind.
