What would be the route from Chinese National Convention Center to Great Wall?

Are you going to visit Badaling or Mutianyu Section? If it is Badaling, it is suggested to walk from where you are to Anhuiqiao North bus stop to take bus no. 380 to get off at Deshengmen Station, where you can find bus no. 919 or 880 to take you to the wall directly.

If it is Mutianyu, still walk to Anhuiqiao North Station to take bus Special line 2 (特2) to Dongzhimen North Station. Then walk to Dongzhimen Waixiejie to take bus no. 867 to your destination directly then.

Thank you so much

I am right now near the Xitucheng station. What could be the subway route to the Badaling section?

Then it is suggested to take subway line 10 at Xitucheng Station to Zhichun Road, where transfer to line 13 to Xizhimen. After that, transfer to line 2 at Xizhimen to get off at Jishuitan Station. Then walk to Deshengmen to take bus no. 919 or 880 to Badaling.
