Detian Waterfall, stretching across the border of China and Vietnam, is the largest transnational waterfall in Asia. It is located in Detian village, Guangxi Zhuang Autonomous Region' Daxin county, which is 78 kilometers away from the county seat and 140 kilometers away from Naning city, the capital of Guangxi.

The waterfall is 100 meters wide. The water curtains are just like pearl necklaces in the mountains. Visitors can enjoy both natural scenery and exotic beauty here.

In the election of "the most beautiful places in China" held by China National Geography magazine, Detian Waterfall was elected "the most beautiful waterfall in China" in October 2005.
