Our first full day we used to visit the Oriental Pearl Tower. There are 2 options to choose from: 263 m Main Sightseeing Floor and 259 m Transparent Observatory. We went for the 263 m options, which for me was not worth to wait two more hours in the line, compared to the 259 m. The glass bottomed sky walk is located on the 259 m floor. Which was really cool, when you stand on it you well the movement of the building.
