Is there a tourist bus leaving from Qianmen going direct to Badaling ? If yes at what time ?

I'm afraid there is no direct bus from Qianmen to there. But you can take subway line 2 from Qianmen to Xizhimen Station first; leave from Exit A2 to reach BJ North Railway Station. You can get on train S2 to the destination in around one hour. There are many train schedules every day. Don't worry.

Thanks Bob. We went to the train station but all trains were booked until midday! We were there around 6.30 ! So finally we took the bus 877 direct to there. It costs 12 yuan.
