Nui Doi Quan Ba called Co Tien Moutain is regarded as an important destination in the tours to Dong Van rocky highland, an attractive place for professional photographers to come.
As told by the legend, there was a young H' mong boy in Quan Ba, the misty highland, who had talent for performing musical sound by his lips; the sound was so melodious like stream flowing and bird singing, so tuneful like the wind spreading our everywhere to the sky that many young female highlanders were softhearted. A beautiful fairy from heaven named Hoa Dao occasionally encountered the music and looked for a performer. They fell in love afterwards and she could not return to heaven. The marriage between the human and fairy was made eventually. The couple had one son.
The Lord knew Hoa Dao escaped from heaven and married with the human. He angrily recalled her back to heaven. Before leaving, she left her breasts to her husband to feed the baby with her breasts milk. The breasts gradually grew up and became the twin mountain like the mother's breasts fully strain with milk. That twin mountain was named Nui Doi or Nui Co Tien.
According to the legend, thanks to “the fairy`s breasts milk”, the weather at the site is cool and thus fruits are grown there give a wonderful taste, such as peach, apricot, persimmon.., rice and vegetable harvests are always successful.
