Hi Shan
Greeting from Peggy, Top China Travel.
The recommended transportation from Mt. Huangshan to Jiulong Waterfall and Jade Valley is renting a vehicle.
Firstly, get back to Tangkou Town from Mt. Huangshan area.
And then, renting a vehicle in the town. Because the shuttle bus to these two sites are hard to wait.
From Tangkou Town to Jade Valley, it is about 10 min driving.
And from Jade Valley to Jiulong Waterfall, it is another 10 min driving.
Generally, a half day can visit these two places together. Firstly visit Jade Velly, and then Jiulong Wanterfall, and then back to Tangkou Town to stay overnight.
Feel free to contact with us in any moment by mail if you have any question on China tour service.
Have a nice day!
Best Regards
Peggy
