I don't think it is possible to visit both Dazu Rock Carving and Yibin Hanging Coffin in one day. You may only visit one of them. There are hanging coffins on the cliffs of Yangtze, but you will need to take cruise to see them. It takes a while to transfer from Wulong Karst to Fairy Mountain. There are three attractions for Wulong Karst, one day is not enough to cover all of them including Fairy Mountain, you can only visit one of the sites and Fairy Mountain in one day.

Thank you. Which is better to visit wulong karst or fairy mountain?

For me, I prefer the Wulong Karst. The landscapes of Three Natural Bridges and Lotus Cave are spectacular and impressive. If you also want to include Fairy Mountain, you can visit Three Natural Bridges and Fairy Mountain in a day.

Thank you very much.
