How can I go to Summer Palace from Landmark Apartments Beijing?

Hell, Ata. I am wondering if you are referring to the Landmark Towers Apartment. If so, I suggest you walk to Liangmaqiao Station to take subway line 10 and get off at Haidianhuangzhuang. Transfer to line 4 to Beigongmen. Leave from exit A, you can walk to the north gate of the park.
