Crossing the Tsang Po river

The Yarlung Zangbo River or Yarlung Tsang Po originates upstream from the South Tibet Valley and Yarlung Zangbo Grand Canyon in Tibet. Downstream from Arunachal Pradesh in India the river becomes wider and at this point is called the Brahmaputra River. It eventually disgorges into the Bay of Bengal. Since the river crosses international boundaries, it has at least three different names in different languages.
