20 hour transit in Chengdu
Hello,
I have a l transit time of 20 hours (largely day time) in Chengdu within an international flight to Europe (end of June).
As a first time traveller to Sichuan, and an English speaker, I was wondering where best to sightsee in Chengdu during that time, that would be easiest to navigate and get to from Tianfu Airport?
I am hoping for somewhere not overly crowded (I am a solo traveller) that is easy to get to by bus or train with either no transfer or an easy transfer there.
Ideally something that is unique to Sichuan / China and safe to walk around alone. ie with beautiful scenery, or a historic site, or unique buildings/area of the city. I would love to go to the Panda Base, but wondering if that is too tricky.
I would have roughly 11 hours of daylight to explore Chengdu.
Thank You!
