This is the first rank of the most beautiful cave in Phu Pha Man National Park. It is completely dark in the cave where the area is divided into the chambers. The stalagmites are shining and sparkling amazingly. In particular, the large drapery in the large hall is hanging and spreading out beautifully. The car is accessible to the foothill where the cave is located.
**** Tourists are not allowed to touch the stalagmites in the cave or collect plants or tree, and aquatic animals in the cave. Please follow the instruction of the officers strictly.
