Hi Goldzy,

Greeting from Peggy, Top China Travel.

As for my suggestion, it is necessary to stay a night on Mt. Huangshan because 1 day is not enough for you to see the highlights of this famous mountain.

Generlly a trip to Huangshan will be:
Day 1 Drive you from Tunxi to Mt. Huangshan area. Around the noon, you will get to the hote on the mountain. And in the afternoon, have a visit to West Sea Grand Canyon. When finish the tour, stay overnight in the hotel on the mountain.

Day 2 Get up early and enjoy a half day sightseeing on the mountain as well. After lunch, down to the mountain and drive you to the bus/airport for you next destination.

And there are about 5 buses (coaches) leaving for Huang downtown from Hangzhou West Bus Termial, which depart from 6:50 a.m. to 6:20 p.m. every day. The price is about 89 yuan. If you want to get to the Mt. Huangshan Scenic Area from Huangshan downtown, you still need to catch a bus in Huangshan Tunxi Bus Terminal. The journey to the scenic area will take about an hour.

In addition, there are 5 buses leaving for Mt. Huangshan Scenic Area from Hangzhou West Bus Terminal, which from 6:00 a.m. to 3:00 p.m. every day. The cost is about 110 yuan.
