From Tuanjiehu Station to Badaling Great Wall: Take metro line 10 to Hujialou Station and metro line 6 to Chaoyangmen Station. Then transfer to metro line 2 to Jishuitan Station, Exit B1. Walk east around 650 meters to find Deshengmen Bus Stop. After arriving, take bus no.877 and the drop-off site is close to the pulley car lower station and about 10 minutes' walk to the entrance. It is a non-stop bus, taking about an hour and costing CNY 12 per person.
From Badaling Great Wall to Longqing Gorge: For your convenience, you are advised to hire a private car to get to the gorge directly.
