Nice exercise, climbing the stairs is a good exercise for the thigh muscle, you probably noticed the next day where every single muscles is attached. That is really weird feeling. To go up you usually get out of breath but going down, you will feel that horrible feeling in your leg muscle. But at the end you are doing it rarely and as tourist everyone keen to see such beauty. It was nice to see your video but believe me I felt with you how it is when you still very keen to finish your tour seeing towers but on other side you are so exhausted that just want to lay down and have some rest. Beautiful pictures, I have not expected such a panoramic view, so it was worth to do that :)
