Dong Lam Magic Valley

Dong Lam Magic Valley is a large karst valley and seasonal grassland in Huu Lien Commune, Huu Lung District, Lang Son Province, about 25 km from Huu Lung town. Surrounded by limestone mountains, the flat valley floor forms a vast green meadow in the dry season and a shallow seasonal lake in the rainy season. It is notable for its pastoral scenery with grazing horses and cattle, and is a center for community-based tourism and camping.

Visitors can expect a wide, flat valley floor covered in grass, encircled by forested limestone karst peaks. In the dry season the area is a dry meadow ideal for walking and picnics, while in the rainy season low-lying parts flood to form a shallow lake. Horses and cattle graze freely, and visitors can explore open grassland, small streams, dirt tracks, camping areas and viewpoints of the surrounding mountains. Homestays and food stalls are available in nearby Huu Lien village.

The valley is located in Huu Lien Commune, home to Tay ethnic communities who practice traditional farming and animal husbandry. The pastoral landscape reflects local agricultural life and community-based tourism developed by Huu Lien village.
