The bay is made of thousands of limestone islands called karsts. 

This landscape took a very long time to form. The limestone itself formed over 500 million years. The shapes of the islands changed over the last 20 million years. This happened because of the tropical wet climate. 
People have lived in this area for a very long time. Research shows prehistoric humans lived here tens of thousands of years ago. Different ancient cultures, like the Soi Nhụ and Cái Bèo, lived in the bay.

Hạ Long Bay is a spectacular marine landscape in northeastern Vietnam. 

The landscape is defined by its unique geological features. The bay contains approximately 1,969 islets. Most of these are limestone karsts, which are tall, steep hills. A karst is a type of landscape formed from the dissolution of soluble rocks. In the core zone, there is a high density of 775 islets. 
The formation of this environment was a very slow process. The limestone itself formed over 500 million years. The specific karst shapes evolved over the last 20 million years. This happened under the influence of a tropical wet climate. 
The bay is a center of high biodiversity. It contains a tropical evergreen biosystem and a seashore biosystem. There are 14 endemic floral species found here. Endemic means they grow nowhere else on Earth. There are also 60 endemic faunal species. 
Human history in the bay stretches back tens of thousands of years. Prehistoric humans lived in this area long ago. Several ancient cultures occupied the region. The Soi Nhụ culture existed from around 18,000 to 7,000 BC. The Cái Bèo culture followed from 7,000 to 5,000 BC. Later, the Hạ Long culture thrived between 5,000 and 3,500 years ago. 
A small population of about 1,540 people lives within the bay. Most reside in four fishing villages: Cua Van, Ba Hang, Cong Tau, and Vong Vieng. 
To protect the landscape, the government is changing how people live in the bay. A project has begun to relocate fishing households to land. Since May 2014, more than 300 households have moved to the Khe Cá Resettlement Area. This helps stabilize lives while protecting the natural heritage zone. Some villages will remain only for sightseeing purposes.
