Head into the front doors and you can pay for different tickets depending on how high up the building you want to go, however don't pay for the most expensive ticket. You may think that the most expensive ticket takes you up to the top floor, but it actually lets you take the Sky walk, you walk around outside the top floor of the building with only a harness keeping you from falling. If you want to do that, I admire your bravery and it probably would be good fun, but don't accidentally buy the wrong ticket. Once you go up the building you can look down and see the countless floors of the huge building and can see the other huge buildings in Shanghai. You can see Shanghai tower, the Oriental pearl and other parts of the city. Wait until it gets dark and you'll see the whole city light up in all of its colours.
