小寨天坑 (Xiaozhai Tiankeng) is the deepest sinkhole of the world. Actually it is two sinkholes in one, an upper, wider sinkhole, a sloping ledge, and another sinkhole in the middle of the bigger.
The Xiaozhai Tiankeng was well known to local people since ancient times. There once was a small village close to the doline which is now abandoned. Its name is Xiaozhai (little village). From the village a trail leads two the rim and down into the sinkhole. It was constructed to allow tourism, but the 2,800-step staircase is not for the faint-hearted.
At the base of Xiaozhai Tiankeng is a river cave named Di Feng Dong (Difeng Cave). The cave river flows out of the opening and across the floor of the huge doline. It has less water than before, because a part of it was redirected for a hydroelectric plant.
Some pages state that Xiaozhai is also called Heavenly Pit. That's actually wrong, all the huge sinkholes here are called Tiankeng which means Heavenly Pit. In other words, Xiaozhai Tiankeng translates Xiaozhai Heavenly Pit.
