Along with 99 other locations in 53 countries around the world, Ha Long Bay - Cat Ba Archipelago was recently recognized by the International Union of Geological Sciences (IUGS) as an International Geological Heritage.
Ha Long Bay - Cat Ba Archipelago was recognized as an International Geological Heritage thanks to two outstanding global values of geological history and karst geomorphology.

Ha Long Bay - Cat Ba Archipelago includes all stages of the marine submergence of tropical karst as well as three main types of caves (ancient marine frog-jaw caves, ancient karst-floor caves and frog-jaw caves).
Karst landforms are landforms of distinctive disintegration patterns often marked by underground cavernous drainage systems.
In 1994, Ha Long Bay was recognized by the United Nations Educational , Scientific and Cultural Organization (UNESCO) as a World Natural Heritage with outstanding universal aesthetic value.
In 2000, Ha Long Bay was recognized by UNESCO as a World Natural Heritage for the second time with outstanding global value in geology and geomorphology.
On September 16, 2023, at the 45th session of the World Natural Heritage Committee, UNESCO recognized Ha Long Bay and Cat Ba archipelago as the first inter-provincial and municipal World Natural Heritage in Vietnam.

Lan Ha Bay Cat Ba tourism is popular with many tourists.
The appearance of the Ha Long Bay - Cat Ba Archipelago area and its unique and famous geological and geomorphological values today are the result of a regional tectonic movement that lasted more than 500 million years. That is also the reason why UNESCO has recognized Ha Long Bay as a World Natural Heritage three times.
