The Da River upstream belongs to the Ka Lang commune in the Muong Te district in the northern mountainous province of Lai Chau,  and originates from the 1500m Weishan mountain in Yunnan province, China.

The Da River is 983km long, with 543km of it in Vietnam, including 232km in Lai Chau province. Of the 230km in Lai Chau, there are 170 waterfalls and 130 whirlpools.

With its long slope and powerful flow, experts list the Da River among the fiercest rivers in Indochina. However, this means the river has abundant hydro-power potential. The three largest power plants in Vietnam are based on this river: Hoa Binh, Son La (under construction) and Lai Chau (approved by the Congress recently).

Dan Tri introduces the unique, wild and gigantic beauty of the Da River.
