Van Long is the largest wetland nature reserve in the Northern Delta. This reserve is located in the northeast of Gia Vien district, ninh binh vietnam. Van Long is now a major tourist destination of Vietnam, which owns two records of the Vietnam record book center in 2010: “Where there is highest number of individuals of Delacour’s langur” and “The place with the largest natural picture”. In 1999, it became a nature reserve, listed in the list of wetland protected areas and a list of systems of special-use forests in Vietnam. Currently, Van Long tourist area is supported by the Dutch government, Global Environment Fund (GEF) and Cuc Phuong Center for Rare Primate Rescue to preserve rare and precious animals.
From 1960, a dyke line of more than 30 km was built on the left bank to regulating the flow of Day River, turning Van Long into a submerged area of up to 3,500ha, captivating migratory birds to live here on the way to avoid the cold. The isolated mountains becoming into stone islands between immense water valley have “coincidentally” become the lifesaver for many animals and plants escaping the hands of human destruction. But the accidental worth is the most when foreign experts discovered Van Long had more than 40 individuals of Delacour’s langur. This finding surprised the scientific community because the Delacour’s langur is a highly endangered species, named in the world red book. In addition to the Delacour’s langur, in Van Long, there are many animal and plant species recorded in the Vietnam Red Book, such as Stangeria eriopus, strychnine tree, Chukrasia, Asian black bear, Neofelis nebulosa, Asian water monitor, etc. In particular, there is a near-extinct insect that is a Lethocerus indicus belonging to the family Belostomatidae. Where these species live must have a truly freshwater environment.
Van Long is an area with a high biodiversity area, a limestone ecosystem is the habitat of the largest populations of langurs in Vietnam with about 100 individuals. The flora and fauna of Van Long is very typical for the limestone and wetland ecosystem of the Red River Delta. In particular, this is a very precious area of biodiversity research for these two ecosystems and is the site for the study of the largest species of Vietnamese langur in Vietnam because of the largest number of individuals, most observable area.
Not only is the nature reserve, but Van Long wetland is also a place with attractive landscapes. Van Long is dubbed “the bay without waves” because when travelling on a boat on the lagoon, visitors will see the flat water like a giant mirror. The water painting reflects clearly the strong sculptures of the limestone massifs with the right shape with names such as Meo Cui mountain, Mount Mam Xoi, Ho Sach Mountain, Da Ban mountain, Nghi mountain, Mo Coi mountain, mountain Ba Tien. However, the water here does not have the blue of the sea, but it clearly shows the layers of moss on the bottom.
Located between the valley with four sides are limestone mountains with spectacular shape, Van Long wetland (Gia Vien district, Ninh Binh) is currently an attractive eco-tourism destination. At any time of the year, Van Long is always attractive to tourists on ninh binh amazing tour, some special moments that tourists on daily cycling tours in ninh binh can consider before deciding to travel to Van Long.
May to June every year, on the surface of the water, Van Long is covered with a pink color of lotus blossom season.
In the dry season (from November 11 to the next year), Van Long is the nesting place for many Northern waterbirds, now the whole area of Van Long lagoon is full of thousands of white birds creating a poetic scene.
