#Discovery #BacSonValley is a rural district of Lạng Sơn Province in the Northeast region of Vietnam and it is situated 160km northeast of Hanoi. One of the interesting aspects about this valley is its incredibly high mountains which are about 500-1200 meters high. These mountains, together with the valley’s paddy fields, create a great scenic landscape that you can only see its best after climbing to the peak of a mountain which is located just a few minutes from the town.
