Hi,
I have only just seen this message, I hope that this can be of some use to you. My husband and I stayed at Wudang Shan for 5 nights during September last year. We went there for Martial Arts training which you may be aware of if you wanted to visit this destination.
How do you plan on getting there?, we took a overnight train and may be able to help you with advise here. Do any of you speak Mandarin? we found communication difficult without it.
You should spend all your time in the mountain it is very beautiful. We stayed at Tian Lu Hotel and recommend it, it is basic but clean and has a good restaurant with a english menu available. It is also very close to the temples (and right next door to purple cloud temple).
The cable car has just been completely restored and was meant to re-start October 2010. It does not operate during thunderstorms which were not a problem when we were there (which is around the same time of the year you are going).
Take comfortable clothes and sneakers, there is a lot of walking to be done and a lot of stairs around the temples.
I hope that you have not canceled your trip due to lack of information. It really is worth going to! Let me know what further questions you have.
Nikki
