Hello, is it possible to do one day trip Jingdong Grand canyon and Jingdong cave from Beijing?

Yes, you can visit there in one day. Generally speaking, the suggested sightseeing time is 4-5.
As specific itinerary, I’d like to list a route to you for reference.
Ticket Entrance – Longmen Lake – Jing & Xian Pond – Wanzhang Cliff – Guai Pond – Ling Pond – cableway – Waterfall of Xiang Pond – cableway – Ling Pond - Tongtian Gorge

Thank you very much for your suggestion.. Is there any map for that tour?
