From Westin hotel to mt.huashan

You can take a taxi from your hotel to the Railway Station, about 7km far. At the east square of the station, there are tour buses to get you to the scenic area directly.

As for the route on the mountain, if you are pressed for time, you can take the cable car to the north peak, and then travel following the route: north peak – east peak – south peak – west peak. At last, you can take the cable car down and take the tour bus back to downtown area.

thank you for the fast response
friday/sunday is better option?

Friday is better, because it may be crowded on Sunday there.
