Here's one little fella who's not afraid of heights.
They hang around the tourists a lot because they think they're going to get fed. There was a crafty one sitting by the doorway to the viewing platform where people couldn't see him as they walked in. They would stop in awe to look at the view and then the monkey would ambush them and try to take their bag! It was amusing to watch. One of the baby ones jumped onto a little girl's back and I saw another one try to steal a man's baseball cap.
