It looks to me like I went in around the same area as Fauster.
Driving north from Beijing through Gubeikou on the Jingcheng Expressway, you will see a hotel and a Wohushan Great Wall sign on the left (west) side.
Shortly before this on the right you can park. On the
Gubeikou map, it's near where it says "Jing Cheng road".
There is a side street which leads up a hill to a courtyard. On the
Gubeikou map, it's labeled Gubeikou old street.
There are temples and a very small museum in the courtyard.
View of Gubeikou from the old street.
