Guangzhou's skyline wouldn't be as colorful without the Canton Tower, one of the world's tallest TV towers. The 112-story building outstretches even Toronto's CN Tower. Resembling a thin champagne bottle, the building turns into a kaleidoscope of color at night. There are excellent photo opportunities on the observation decks and a section of transparent floors where you can get an eagle's view of the cityscape. The tower features the world's tallest Bubble Tram, which has 16 transparent passenger cars. One revolution takes about 20 minutes. There are also two revolving restaurants and a coffee shop.
