A New Chapter for Vietnam’s Heritage: Exploring the Majestic Cat Ba Archipelago with Stellar of the Seas
The world has officially turned its gaze toward Vietnam once again. We are immensely proud to announce that the Halong Bay – Cat Ba Archipelago has been officially recognized by UNESCO as Vietnam’s first inter-provincial World Heritage Site. This historic milestone marks the first time in eight years—since the second recognition of Phong Nha-Ke Bang in 2015—that Vietnam has celebrated such a prestigious global honor.

The Grandeur of a World Natural Heritage
While Halong Bay (Quang Ninh Province) has long been a global icon with its two-time UNESCO designation in 1994 and 2000, the addition of the Cat Ba Archipelago completes a masterpiece of nature. Located just south of Halong, Cat Ba is Vietnam’s largest limestone archipelago, comprising nearly 400 emerald islands.

Beyond its breathtaking landscapes, Cat Ba is a sanctuary of biodiversity. Spanning over 17,000 hectares, it serves as a home to 198 species listed in the International Union for Conservation of Nature’s Red List, making it a vital ecological treasure of the world.
