We climb up here in the late afternoon - a good choice not too many people as all the buses had left for the day. A bit of a climb for us older citizens but was actually easier that I expected and although narrow it was very well maintained. The views for the top were amazing - evening is a good time to go. Using one's imagination it is not difficult to imagine what an amazing place this was at the height of the civilisation. We did not have any of the issues mentioned by other reviewers eg being hassled, however that may be because of the way we handle it - around the world this is not an unusual experience. Would thoroughly recommend this experience unless you are really scared of heights but if possible make the climb.
