Are there different cable car systems to go up the Hua Shan ? Treying in mid October.Thanks

Yes, there are two routes for the cable car service.
One is Donggoukou - White Sparrow Temple - West Peak (mountaintop).
The other is Wamiaogou - North Peak (half of the mountain).
If you want to experience more hiking, I suggest you choose the latter route, well, if you feel physically challenged, I suggest you choose the former rouote.
