World Natural Heritage
Halong Bay was formed by millions of years of geological changes, which created thousands of islands. Hidden inside these are beautiful caverns such as Sung Sot, Thien Cung, Trinh Nu and Thien Canh Son Caves, and Thien Cung Grotto.
Recognized by UNESCO as a World Natural Heritage site for its biodiversity, geology and nature, Halong Bay’s beauty and charm make it an outstanding tourism destination. The landscape of Halong is attractive in each season.
