Howard Johnson Paragon Hotel, right? But do you refer to Badaling Great Wall or Mutianyu Section? Anyway, it is around 69km from Badaling, around 75km frm Mutianyu. It is a little further than 50km from Ming Tombs. Around 15km from Bird Nest. Which Hutong are you referring by the way?
Oh, all above is the driving distance.
