Situated some 160 kilometers from Hanoi in the far north, Bac Son was once not as well known as other destinations like Sa Pa in Lao Cai Province or Mu Cang Chai in Yen Bai, but has now found a place on the tourism map with its pristine beauty.
Farmers in the valley in Quynh Son Commune, which borders China, grow two rice crops a year and harvest them from late July and early November.
The rice harvest season in Bac Son Valley begins sooner than in other places and lasts about a week.
The area is home to 400 families belonging to ethnic groups such as the Tay and Nung who live in traditional stilt houses and mainly depend on farming.
