Gubeikou

Gubeikou is an area known for its unrestored sections of the Great Wall of China, for example the Jinshanling area of the wall. Because it is unrestored, it's a lot less crowded, and this also means that you will be walking on an authentic part of the Great Wall.

You can reach Gubeikou easily by train from Beijing. The train will leave from Beijingbei or Qinghe Railway Station, all will cost around 2 euros. You will need to take the provincial S-train, instead of the usual high speed train. Once you are at Gubeikou Railway Station, there will be taxis waiting to bring you to where you want to go. Didi is not available in this area, so you will have to negotiate a price in person.
