Halong Bay, in the Gulf of Tonkin, includes some 1,600 islands and islets, forming a spectacular seascape of limestone pillars. Because of their precipitous nature, most of the islands are uninhabited and unaffected by a human presence. The site’s outstanding scenic beauty is complemented by its great biological interest.
All elements necessary to sufficiently protect the outstanding scenic and geological values of the Halong Bay property are included within the boundaries of the property and its size and area provide sufficient integrity for the large scale geomorphological processes to operate unhindered. It benefits from being completely surrounded by a large and extensive buffer zone with both the size and area providing sufficient integrity for the large scale geomorphic processes to operate unhindered.
Located within an area of high tourism, marine transport, fisheries and the daily activities of people living and conducting their business on Halong Bay, management of the area, instituted since inscription of the property, applies strict regulation and control of activities in an attempt to minimize impacts on the integrity of the property. There is a continuing challenge to improve the integrity and quality of the environment. The natural scenic features, geomorphology, landform values and cultural heritage along with key features such as islands, caves and grottoes remain intact and the property retains a high level of naturalness despite the long history of human use in the area.
