The five caves of On Village are attached to the Eastern philosophy of five basic natural elements: Metal, Wood, Water, Fire and Earth. To reach Cave Number Three, you'll have to go deep into the valley of Tan Lap Commune, 16km away from Moc Chau Town. As the journey proceed, you'll see the landscape changing from gentle green tea hills to thick primeval forest. The path isn't easy but it's worth it.
The Cave Number Three welcomes you with its sparkling stalactites looking like they are dripping down from the ceilings. Other karst structures with many different shapes and sizes will arouse your own imagination like a floating cloud, an animal, or a woman.
