Ban Gioc–Detian Falls

Detian Waterfall is a waterfall in the Karst hills of Daxing County in Guanxi Province in China along the border with Vietnam. It is the second largest waterfall along a national border after Niagara Falls and was one of the crossing points for China’s army during the brief Sino-Vietnamese War. Nearby there is the Tongling Gorge accessible only through a cavern from an adjoining gorge. Rediscovered only recently, it has many species of endemic plants, found only in the gorge, and used to be used as a hideout by local bandits whose treasure is occasionally still found in the cliff-side caves.
