Room without AC and shared bathroom for 40 RMB. (Room 202).
This lonely planet hotel is located on the top of Dazhai village on the way to Tiantou village. The hotel, well... it is more like a wooden hut, is run by a friendly family that were learning English with an on-line course (the hotel had one PC with free internet). The best of the place were the views and the restaurant; what a great experience eating such good meals watching this incredible landscape. However, since the hotel stood a little way from the village (10 - 15 min walking) guest usually eat there. We spent 220 RMB in two dinners and two breakfast, which was a correct price.
If you want to visit Longsheng Rice Terraces you have to choose between Dazhai area or Ping'an. From our point of view, Dazhai is a better option since, even been tourist, it was less crowded and the view points were not like an amusement park. We strongly recommend to do the hike between Dazhai and Ping'an which took about 5 hours. We lost the last bus from Ping'an to Dazhai and a taxi cost us 60 RMB.
