Ban Gioc–Detian Falls

Ban Gioc–Detian Falls is a waterfall on the Quay Son River in Cao Bằng, Vietnam, extending 200 meters in width. The water drops 30 meters over several limestone tiers, while bamboo groves and rice terraces cover the surrounding slopes.

The falls have marked the natural boundary between Vietnam and China for centuries, with the border running through the middle of the cascades. Local communities on both sides shared the river for agriculture and trade for a long time.

Locals call the falls Ban Gioc on the Vietnamese side and Detian on the Chinese side. The border location makes this a place where two countries share the same landscape.

Visitors reach the falls by bus from Cao Bằng city, with the journey taking around four hours. October brings clear weather and strong flow, while the rainy season increases the volume.

The falls divide into three sections separated by rocky outcrops. The left section fills with water only during the rainy season and remains dry in other months.
