Thac Ba lake is an artificial lake located in the North West of Vietnam. It is about 180km from Hanoi in Luc Yen and Yen Binh districts of Yen Bai
This artificial lake has an area of 23,400 ha and 1,331 islands and hills with diverse ecological environments. The water in the lake is blue and clear, and imprinted with the reflections of the surrounding ancient forest. The thousands of hills and islands feature caves such as the Hum, Cau Cuoi and Bach Xa. The Thac Ba Temple always draws visitors.
Thac Ba Lake is not only a beautiful landscape, but it is also a national vestige. In 1285, the Thu Vat Battle took place under the command of Tran Nhat Duat against Mongolian invaders.
There are plans in the works to develop Thac Ba Lake into an ecological tourist centre with entertainment, mountain climbing and hiking.
