What Are Quan Ba Twin Mountains?
Quan Ba Twin Mountains is one of the most famous landmarks in Ha Giang province, Vietnam. The local name is Nui Doi Quan Ba. In English, people call it Quan Ba Twin Mountains or Fairy Bosom Mountains.
The mountains sit in Tam Son town, Quan Ba district, Ha Giang province. They are located in the southwest part of the Dong Van Karst Plateau Global Geopark.
The two mountains are round and nearly equal in size. They stand side by side. Each mountain has a circumference of nearly 1,000 meters. The total area is about 3.6 hectares.
Scientists say the mountains formed between 1.6 million and 2 million years ago. They were created by movements of the earth’s crust. Limestone rocks broke apart over time. The result is two perfect, dome-shaped hills rising from flat farmland.
The Legend of the Fairy Mountains
Every visitor who comes to Quan Ba Twin Mountains will hear the local legend. The Mong ethnic people have told this story for generations.
Long ago, a young Mong man lived in this area. He was talented and played a traditional instrument called the dan moi, or jaw harp. His music was so beautiful that it floated all the way up to heaven.
A fairy named Hoa Dao heard the music. She fell in love with him. She came down to earth and married him. Together, they had a baby boy.
When the Jade Emperor found out that Hoa Dao had left heaven, he was very angry. He ordered her to return. She begged to stay and care for her child. Her request was denied.
Before she went back to heaven, she left her breasts on earth so her baby could still be fed. The child grew up healthy and strong. Over time, those breasts turned into the two round mountains we see today.
The legend also says her tears of sadness became the Mien River. The river flows through the rocky landscape around Quan Ba. Local people believe that because of the fairy’s milk, the land here is fertile and full of life.
