Detian Falls

Detian Falls straddles the border between China's Guangxi Zhuang Autonomous Region and Vietnam's Cao Bằng province. On the Vietnamese side, the falls are known as Ban Giốc (Thác Bản Giốc).

Detian Falls is widely regarded as one of the largest transnational waterfalls in Asia, with water from the Quây Sơn River cascading across multiple tiers along the border. Its scale and karst-limestone setting make it a major tourist destination in the region.

Yes, both countries have developed tourism infrastructure on their respective sides of the falls. The Chinese side is accessible from the city of Chongzuo in Guangxi, while the Vietnamese side can be reached from Cao Bằng city.

Detian Falls is formed by the Quây Sơn River (called Guichun He in Chinese), which flows along the China-Vietnam border through a dramatic karst landscape. The river eventually merges into the broader river system of the region.
