A better way would be to take the Yungu Cable car to White Goose Ridge Station in the morning. From here trek to Beihai hotel and proceed to Xihai. Along the way you can visit the peaks as well. Not a difficult trek which can be done in a morning. From Tangkouzhen to the Huangshan Scenic area there is a dedicated bus service which costs 19 yuan. The bus stop is next to Cheng Zin hotel.

You can leave your luggage at the Tourist Activity Center. This is located on the same plaza where you take the bus to go to the mountains. Luggage storage costs 10 yuans per day per piece. Note the Activity Center closes at 5 pm.
