I remember it took me one and a half hours from Xian to Hua Shan by car. Well, different people may have different answers for this question. Personally, I enjoyed my visit to Huaqing Spring because I like the charming spring scenery and the romantic love story of the Emperor Xuanzong and the concubine Yang in Tang Dynasty. Only the Banpo Museum is open to tourists. It is built at the base of Banpo site, so you can see some of the excavations. That’s all I can tell you and may you a nice stay.
