Bac Son Valley

Bac Son Valley is a broad agricultural valley in Bac Son District, Lang Son Province, northeastern Vietnam, about 160 km northeast of Hanoi. Encircled by limestone karst mountains, it is known for its patchwork of rice paddies, winding rivers and traditional Tay stilt-house villages. The valley is best viewed from Na Lay Peak and is notable for seasonal color changes, rural scenery and well-preserved ethnic village life.

Visitors can expect a wide, flat valley floor covered with geometric rice fields surrounded by dramatic limestone karst peaks. The main viewpoint is Na Lay Peak (about 600m elevation, reached by ~1,200 stone steps) offering panoramic views of the patchwork fields and villages below. At valley level, visitors can explore Tay ethnic stilt-house villages such as Quynh Son, cycle or walk along village paths and rivers, and observe seasonal farming activities.

Bac Son is known as the site of the Bac Son Uprising in September 1940 and has a long history of Tay settlement and wet-rice agriculture. The Bac Son Museum in the district town exhibits artifacts related to local history and archaeology.

The valley is a cultural heartland of the Tay ethnic group, known for traditional stilt houses, communal houses, folk songs and festivals, and a landscape shaped by centuries of terraced and valley rice cultivation.
