You must refer to the Great Wall, right? There are several sections around the city. I'f reocmmend Badaling Section to you. To reach there, you can take subway line 9 from the West Railway Station to National Library and transfer to line 4 to get off at Xizhimen. Leave exit A1 and walk to the North Railway Station to take a train to Badaling in an hour, with the cost of CNY6. The metro fare is CNY4 per person.
