Phong Nam Valley

Phong Nam Valley is a broad karst valley in Phong Nam Commune, Trung Khanh District, Cao Bang Province, northern Vietnam, within the UNESCO Cao Bang Global Geopark. Notable for its flat rice paddy fields framed by limestone peaks, winding village roads and traditional Tay and Nung stilt houses along the Quay Son River, the valley is valued for scenic rural landscapes, seasonal rice colors and tranquil village scenery near Ban Gioc Waterfall.

Visitors can expect a wide, flat valley floor covered with rice paddies and small farming hamlets, encircled by limestone karst mountains. Paved and unpaved village roads wind between fields, stilt houses, and streams feeding the Quay Son River. The area is open and rural with viewpoints from low hills and roadside stops for photography, walking and cycling through villages and fields. No large built structures, mainly natural scenery and agricultural landscape.

Phong Nam Valley lies within the Cao Bang UNESCO Global Geopark, recognized for its karst geology and long-standing agricultural settlement. The valley has been cultivated for generations by Tay and Nung communities and retains traditional farming and stilt-house architecture.

The valley is home to Tay and Nung ethnic communities, known for stilt houses, wet-rice cultivation, folk traditions and local festivals. The landscape reflects traditional rural life and agricultural culture of northern Vietnam's border region.
