On a tour of Macau we were taken to the Macau Tower. We didn't have any desire to go there before, but were happy we did. The tower gives you a lovely view of Macau, and China. There were many activities available including bungy jumping and the Sky Walk (where you walk around the outside of the tower).
It is worth the visit if you are visiting Macau.

But I do have to say, Toronto's CN Tower is still taller! (yes we are from Toronto, Canada)
