Plain Walk The same as Macau Tower, Canton Tower is equipped with Sky Walk. What is the difference between them? Sky Walk of Canton Tower is the longest spiral stair case design in the world. Its vertical trek begins on the 32nd floor of the tower and ends at the 64th floor. The climb is 1000 meters and will require some level of physical stamina. The Sky Walk is a thrilling way to see the superb architecture of the tower while testing your endurance.  From the picture, it is easy to find that it is not so exciting as Macau Tower Skywalk. It seems too safe at Canton Tower to "sky" walk. Instead of being surrounded by railing, experiencers step on the edge of ground above the "sky", leisurely but not dangerously.
