Don't look down. Especially if you are afraid of heights. It was really weird to be walking on the glass floor in the Calgary Tower - i found myself constantly walking on the metal beams because it was just too weird to be walking straight on the glass floor it self.
But on the plus side there is fabulous views of the mountains and marvelous views of the City of Calgary, goregous!!
