The Badaling Great Wall is located in Yanqing County. A reasonably long expanse of the wall has been restored here. The scenery is excellent. But there are a lot of tourists here and it can get crowded. Access to the wall is extremely easy here. You can drive right up to it.
Good advice
Famous dead end at Badaling
South-West side
Tower 5
End of the restored South West section - tower 6
Once you pass the end of the restored section, the going gets rough fast.
