Location: Covering the entirety of the four mountainous districts of Ha Giang  Province, including: Quan Ba, Yen Minh, Meo Vac and Dong Van. 
Characteristic: Dong Van Karst Plateau is the first geological park of Viet Nam recognized as a member of the Global Geo-parks Network by GGN.  
From Ha Giang City, visitors  travel on National Highway 4C for 43km to Quan Ba. Continuing on this  highway through Can Ty Pass, pine forests, steep drops, deep ravines,  and razor sharp turns, visitors will reach to the karst plateau. 
Located on an altitude of 1,000m-1,600m, the 2,350km - Dong Van Karst Plateau is one of Viet Nam's special limestone areas, housing prominent  imprints that depict the development of the earth's crust. Up to 80% of  the karst formations of Dong Van Plateau are limestone formed by  environment conditions and different development stages of nature. 
A survey conducted by  scientists from the Viet Nam Institute of Geosciences and Natural  Resources revealed the finding of 11 fossil - geological formations in  Dong Van, including Chang Pung, Lutxia, Sika, Lang Xang, Si Phai, Toc  Tat, Lung Nam, Bac Son, Dong Dang, Song Hien and Hong Ngai. Of which,  Chang Pung is the oldest one with date of 545 millions years. In  addition, 17 paleontology groups were also discovered in Dong Van,  including Brachiopoda (Tay cuon), Trilobita (Bo ba thuy), Gastropoda  (Chan bung), Foraminifera (Trung lo), Cephalopoda (Chan dau), Crinoidea  (Hue bien), Tentaculies (Vo non), Conodonta (Rang non), Tabulata (San ho  vach day), Tetracoralla (San ho bon tia), Stromatoporoidea (Lo tang),  Spirulina (Tao), Bryozoans (Dong vat dang reu), Bivalvia (Hai manh vo),  Hydrilla verticillata (Thuc vat thuy sinh), Sclerotesta (Vo cung),  Polybranchiaspis liaojiaoshanensis (Ca co). The paleontology groups have  helped scientists draw a complete picture of development history in  terms of geology of Dong Van Karst Plateau in particular and northeast  Viet Nam and south China in general. 
Thanks to weather changes  and Dong Van's geo-diversity, the karst evolution has created "rock  gardens" and "rock forests" of diverse forms in the area, such as Khau  Vai rock garden (Meo Vac) where you can contemplate the peaks of rocks  in the shape of different kinds of flowers, Lung Pu rock garden (Meo  Vac) with animal-shaped rocks such as tiger and dragon, Van Chai rock  garden (Dong Van) with round flagstones arranged like thousands of black  sea lions leaning one another getting some rest on the beach. However,  found commonly here are ranges of mountains running one after another to  form pyramids heading up to skies. A system of caves and grottos found  in the Dong Van Plateau provides a proof of the evolution of karst with  Rong Cave in Sang Tung (Dong Van), Kho My Cave in Tung Vai (Quan Ba), En  Grotto in Van Chai (Dong Van)... 
The scientists have evaluated Dong Van Plateau as having a unique and diverse mountainous geo-ecosystem. Primitive forests here have been rather undamaged, habiting many rare floral species, including Burretiodendron hsienmu (Nghien), Taxus Wallichiana Zucc (Thong do), Amentotaxus hatuyenensis (De tung soc nau), Cephalotaxus hainanensis (Dinh tung), Podocarpus pilgeri Foxw (Thong tre la ngan), Cupressus funebris (Hoang dan ru).., especially over 40 species of orchids. Dong Van Plateau also has a rich diversity of habitat for fauna as scientists have spotted over 50 species of wild animals, birds and reptiles in the site such as Capri conrnis sumatresis (Son duong), Rhinopithecus avunculus (Vooc mui hech), Sus cristatus (Lon rung), Garrulax canorus canorus (Hoa mi)...

Besides geological, geomorphology and scenic values, Dong Van Karst Plateau reflects traditional cultural richness of 17 ethnic minority groups, such as Mong, Dao, Lo Lo, Tay, Nung... These ethnic minorities have lived with the rocks. Here, the rock gardens dotted with green corn fields and golden rice fields. In addition Pho Bang, Dong Van, Lung Cu, Sa Phin markets coupled with time-honoured ethnic festivals, rituals, customs and culture of local inhabitants weight the plateau's unique charm.
Visiting Dong Van Plateau in  the spring, you are hit by wonderful landscapes composed by yellow cai  (kale) flowers and pink peach flowers in full blossom, mossy tiled roofs  of stilt houses, dark green rocks and blue skies. Far in deep valleys  covered by pure white plum flowers in full blossom hear remote sounds of  khen (pan-flutes) of Mong people. The season covers rugged rocks and  mountain peaks with its bright colors.
On October 3, 2010, in  Lesvos (Greece), Dong Van Karst Plateau was recognized as official  member of Global Geo-parks Network (GGN) for its prominent values on  landscape, palaeobiology, geology, geomorphology and local culture. Dong  Van Karst Plateau has become the first geo-park of Viet Nam and the  second one in Southeast Asia (after Langkawi Geo-park in Malaysia).
