Geologically, Dark Cave is a karst cave, formed about 400 - 500 million years ago through the weathering and erosion of limestone by water. The cave is approximately 5,258m long, featuring many small branches and underground lakes inside. True to its name, Dark Cave receives almost no natural light, creating a mystical and untouched atmosphere. The stalactite system inside the cave still retains its original beauty with many unique shapes.

The mineral mud in Dark Cave was formed from the accumulation of natural minerals, mainly through millions of years of limestone weathering. Underground streams flowing through geological layers carry precious minerals such as calcium, magnesium, iron, zinc, sodium..., combined with organic sediments, creating a fine and nutrient-rich mineral mud layer.
