Please tell me the distance and time duration from Beijing Airport to Badaling, Great China wall?

It is about 70km from Beijing capital airport to Badaling Great Wall. If you take a taxi, it will take about 2 hours, and the taxi fee is around CNY700 for a round-way. To be frank, no taxi driver will take you to Badaling just for one way and drive back to Beijing on his/her own, since Badaling is located far away from downtwon, few people would take a taxi from there to Beijing. Even if you will just need one way driving, the driver may charge two-way fee. From Badaling, there is only train to Beijing north railway station where there is no train to Shanghai, and you still have to transfer to Beijing South railway station to take a train to Shanghai.
