Leye Tiankengs (lè yè tiān kēng 乐业天坑) in Leye County (lè yè xiàn 乐业县), Baise City (bǎi sè shì 百色市) of Guangxi Zhuang Autonomous Region (guǎng xī zhuàng zú zì zhì qū 广西壮族自治区) are rare karst cave in the world. Local people call them Dashiwei (dà shí wéi 大石围). They came into shape 65 million years ago, like a huge funnel hiding among the high mountains and lofty hills. They are acknowledged as the greatest Tiankeng in the world.

  
At present, people only discover Tiankeng in Russia, Australia and Guinea. In recent years, three tiankengs, which are about 300 meters deep, are discovered in Chongqing. Leye Tiankeng is made up of 23 Tiankengs, the deepest of which is more than 600 meters. Leye Tiankeng almost covers all kinds of tiankeng and karst caves. It is regarded as the Museum of Tiankeng and the holy land of karst landscape.

The virgin forest in the bottom of the Dashiwei Tiankeng (dà shí wéi tiān kēng 大石围天坑) is the largest one in the world. Moreover, scientists discovered lots of cave nesting animals. Two of them are acknowledged as the new species and named as Xi Crab (xī xiè 溪蟹) and Ghost Spidder (yōu líng zhī zhū 幽灵蜘蛛). The underground hall in Dacao Cave (dà cáo róng dòng 大曹溶洞) is the biggest one in China and the second biggest in the world, which is 300 meters long, 200 meters wide and the highest point of which is up to 260 meters. The vegetations in the bottom of the Tiankeng is not only a gene bank but also provides worthy materials for scientific research of the environment and weather in ancient times.

Standing on the top of the west peak in Leye Tiankengs, which is 1660 meters above sea level, you will feel that the white clouds are just above your head. Looking down at the bottom, the steep cliffs around will make you feel like flying in the sky.
