The northernmost upland province of Ha Giang is well known for the Dong Van Karst Plateau.
According to UNESCO, which designated the plateau as a UNESCO Global Geopark in 2015, around 60% of the plateau’s surface is limestone. High mountains and deep canyons are what captivate all those who visit the mountainous district of Dong Van. Mieu Vac Mount is the highest peak, at 1,971 meters above sea level, in Meo Vac Municipality while Tu San is known as Southeast Asia’s deepest canyon (700-800 meters deep). Following are the snapshots of unspoiled nature in Dong Van.
