Is 1 day enough to see Tiananmen Square, the Forbidden City and Badaling Great Wall?

One day is enough to visit the three places. While there are other highlights in Beijing, such at the Temple of Heaven, the Summer Palace, the Hutong tour. So if you have an extra day available for Beijing, I would like to suggest you visit other attractions. November is in early winter and it will be cold in Beijing. We suggest you bring warm clothes.
