At around 8:00am, your private tour guide, driver, and vehicle will pick you up from your hotel in Tianjin (or Tianjin Cruise Port) and drive to Huangyaguan Great Wall which runs on the ridge of mountains to the north of Tianjin. But if you want to start the tour a little late, please tell us at the time of booking. Huangyaguan Great Wall is listed as one of the cultural heritage of the world and one of the ten most popular attractions in Tianjin. It was initially built in Northern Qi Dynasty (550 A.D.- 577 A.D.) and later renovated and extended in Sui Dynasty (581 A.D. - 618 A.D.) as well as in Ming Dynasty (1368 A.D. - 1644 A.D.). The original wall of this section has a length of 26 miles (42 kilometers) but suffers extensive damage throughout its long history.
