Dear Jim Ennis,
Greetings from Janet, Top China Travel. Thanks for your message. The temperature in Zhangjiajie City in Oct is normally 17-28, the temperature at top of mountain is lower than it but it's not so cold, I would say it's cool. Bring one cotton-padded jacket is enough.
Could you please let me know more details about your plan?
How many days will you plan to stay in China and how many clients travel?
Where will you arrive and depart from China?
Which star hotel do you prefer to stay?
Hope the above is clear and helpful.
Looking forwards to hearing from you soon. Should you have any additional questions, please feel free to contact us.
Best regards
Tina
