We're going to Beijing this March and we're gonna stay in Peninsula Hotel Beijing. We want to visit Badaling Great Wall. How can we go there by using the subway? Somebody told me that I should try this route. Take the Wangfujing station (Line 1), then there's interchange Xidan we have to transfer to Line 4 and continue our journey to Xinjiekou station. Then get off the subway, walk to Deshengmen Bus Station, and then take Bus No. 919 to the Great Wall. Is this accurately right? We want to take the subway to experience how it is to ride there. =) Thanks in advance!
