Situated in the northernmost of Vietnam, icluding all four mountainous districts in the north of Ha Giang are Quan Ba, Yen Minh, Dong Van and Meo Vac on an area of about 2,345km2, Dong Van Rock Plateau is honored to be recognized by UNESCO as Vietnam’s first Global Geopark since 2010.

Dong Van Karst Plateau Geopark is the main thing to do in Ha Giang. Recognized as a member of UNESCO Geopark Network, Dong Van features a vast area of limestone which covers most of the four provinces of Ha Giang. Located on the height of 1400 – 1600 meters above sea level, the geographical characteristics of Dong Van Plateau are just as dramatic as it can get with sheer mountain cliffs running to the horizon. The 2,356sqkm of Dong Van Karst Plateau is one of Vietnam's special limestone features besides other excellent examples such as Halong Bay or Phong Nha - Ke Bang National Park, housing prominent imprints that depict the development of the earth's crust and natural phenomenon.
