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.
