Tien Son Cave is located in the Ke Bang Mountain, beneath other caves. Nearby, only 400 m away, is the famous Phong Nha Cave. It seems the two caves are different stages of cave development. As Tien Son is much higher, it is the older, fossil level. It is a dry cave, as the level of the karst groundwater is below at the level of Phong Nha. This cave is developed for 400 m, with paths and electric light.
