Chuandong Tiankeng
穿洞天坑
A sinkhole you can descend into via a cave passage, with ancient trees and vines covering the floor; a rewarding hike.
Chuandong Tiankeng gets its name from cave passages in its walls that connect to the outside world. It is about 312 metres deep and is the representative sinkhole in the Leye cluster where visitors can hike all the way down to the bottom.
Descending along boardwalks and through cave passages, you'll see dense primeval forest on the floor, huge stalactites and hanging vines. The return trip requires climbing back up the same way. The round trip takes about 2 to 3 hours and demands a reasonable level of fitness.
It is usually included in the Dashiwei Tiankeng scenic route. Check the day's opening status and book in advance. Wear non-slip shoes after rain.
