Detian Transnational Waterfall

​Overview​​
The ​​Detian Transnational Waterfall​​ (Chinese: 德天瀑布; Vietnamese: Thác Bản Giốc) is a crown jewel of Guangxi’s natural wonders, straddling the border of ​​China’s Daxin County​​ and ​​Vietnam’s Cao Bang Province​​. Recognized as a ​​AAAAA-rated scenic area​​ (China’s highest tourism classification), it spans ​​200 meters wide​​ with a ​​70-meter vertical drop​​, forming a three-tiered cascade fed by the ​​Guichun River​​.

​​Geographical Significance​​

• ​​Transnational Uniqueness​​: Shared with Vietnam’s Ban Gioc Falls, Detian is part of a singular hydrological system, ranking as the ​​4th largest transnational waterfall globally​​ after Iguazu, Victoria, and Niagara Falls.
• ​​Hydrology​​: The Guichun River loops through Vietnam before returning to China, creating the waterfall’s dramatic plunge. Annual water flow averages ​​55.2 m³/s​​—triple that of China’s Huangguoshu Falls.

​​Natural Features​​

• ​​Three-Tiered Structure​​:
  1. ​​Upper Tier​​: A sheer 30-meter drop into a turquoise "sky pool," generating misty rainbows at dawn.
  2. ​​Middle Tier​​: A gentler slope through limestone channels, ideal for close-up photography.
  3. ​​Lower Tier​​: A thunderous 40-meter finale into the ​​Longtan Pool​​, where bamboo rafts ferry visitors to the base.
• ​​Seasonal Variations​​:
  • ​​Summer (June–November)​​: Peak flow transforms the falls into a roaring curtain.
  • ​​Spring​​: Blooming kapok trees add fiery red accents.
  • ​​Winter​​: Serene, multi-stranded flows create ethereal ice-blue ribbons.
