I am travelling to chengdu Nov 13 to see pandas do you suggest seeing them at Bifengxia as well?

It is suggested to visit the Panda Breeding and Researching Center near CD instead of Bifengxia.

I was planning to see pandas at cd as well as Bifengxia do you not think its worth the extra travel if time permits?

Not necessary to see panda in Bifengxia, November is a low season ,so CD Panda Base is quiet enough,and also temperature at that time should be cool enough for the pandas,they will be active and keep outside . We go to Bifengxia mostly in Summer,when the temperature is too warm in CD.
