Mu Cang Chai is in Yen Bai province near Lao Cai where is one of the most beautiful terraced rice field in Vietnam. It owns 700 hectares of terraced rice fields, with 70 percent at three communes: La Pan Tan, Che Cu Nha, De Su Phinh. For the place being about 1000 meters above sea level, the steep hills make it almost impossible to grow rice fields like those in the delta. Thus local residences grow their own rice on the terraced fields, for the purpose of preventing water from flowing downhill. September and October is suggested as the most ideal time to visit Mu Cang Chai as everywhere, from magnificent mountains or beautiful terraced rice fields are bathed in glistening rays.
