Hotel+itinerary on Mt. Huangshan

1. Yes, staying on the top of mountain is recommended. You will see the beautiful sunrise in the next morning.
2. These are two different places. Tangkou is at the mountain foot, much closer to the gate of scenic area. Tunxi Town is still about 40 miles (60 km) away.
3. I remember that there are about 15 hot springs. Most of them are located at halfway up the mountain and the mountain foot.
4. You are suggested to climb up from the back side first. Then visit Lion Peak, West Sea Scenic Area and other main attractions. BTW, there are cable cars available.

Thanks Adele.
Do you have any recommend hotel at top of mountain? Must I book hotel at Tangkou?
Is scenic area is area where yellow mountain located?

Thanks a lot

Beihai Hotel on the mountain top is recommended. It is clean with nice environment and facilities. Recently, it coasts about CNY 300 per room per night.
What do you mean by"must"? You don't need to book a hotel at Tangkou. There are many hotels there. If you want to stay one night there, you can book one upon arrival as it is not peak season recently and there should be rooms left.
The mountain has been developed into a scenic area, that's why it's called the scenic area by someone.
