The system of islands and caves
Most of the islands on Ha Long Bay are limestone and were formed over
500 million years ago, and are massed in the southeast and southwest.
The schist islands scattered in the southeast have an average height of
between 50-200m, and have a rich covering of flora.
Within the islands of the Bay there are hundreds of beautiful caves of different shapes and sizes, including many famous names such as Thien Cung, Dau Go, Sung Sot, Tam Cung and Bo Nau. Some of them are archaeological sites retaining tangible archaeological evidence, such as Dau Go, Bo Nau, Sung Sot, Soi Nhu, Tien Long, Me Cung, and Trinh Nu caves.
