Three Natural Bridges

The Three Natural Bridges (simplified Chinese: 天生三桥; traditional Chinese: 天生三橋; pinyin: Tiānshēng Sān Qiáo) are a series of natural limestone bridges located in Xiannüshan Town (仙女山镇), Wulong District, Chongqing Municipality, China.

[1] They lie within the Wulong Karst National Geology Park, itself a part of the South China Karst-Wulong Karst UNESCO World Heritage Site.

[2] In Chinese, the bridges are all named after dragons, namely Tianlong (Chinese: 天龙桥; lit.

[3][4] Spanning the Yangshui River, a tributary of the Wu River, the bridges are at the centre of a 20 km2 (7.7 sq mi) conservation area which also includes: Given that the distance between the upper end of the Tianlong Bridge and the lower end of the Heilong Bridge is only 1,500 m (4,900 ft), these are not the longest natural bridges.

Between the bridges lie the Qinglong and Shenying tiankengs which have a depth of 276–285 metres and a circumference of 300–522 metres.
