This enormous cave system may be explored on a 3,000m long tourist trail.
The tour includes 18 chambers, a cave river and a resurgence, karst windows, and
a wealth of speleothems.
The tour shows three different passages of the cave which are called Luyuan
Cave, Yuzhu Cave, and Biyu Cave, each with characteristic
speleothems.
Luyuan Cave is a 760m long passage, a series of ten chambers connected by narrow
paths.
The biggest chamber can hold 4.000 people.
An abundance of speleothems of various forms are named in the typical Chinese
way with colourful and poetic names.
Yuzhu Cave has a length of more than 800m.
The ceiling in this passage is very high, which is the reason for the formation
of typical palm trunc stalagmites.
The most impressive single formation is the the Jade Pillar Supporting the
Sky, a pilar or stalagnate with a height of eight meters and a diameter of
about 30cm.
The 800m long Biyu Cave contains a crystal clear cave river which is called
Yusun River.
It is populated by blind cave fish, which can sometimes be seen on the tour.
