Discover the Unique Terrain and Grand Scale
Tam Giang Lagoon is a lagoon system with complex and diverse terrain, stretching nearly 24km from the O Lau river mouth to Thuan An lagoon. Covering an area of up to 52km², it is the largest lagoon system in Vietnam. A prominent feature of the terrain here is the intersection of freshwater from rivers and saltwater from the sea, creating a brackish water zone with a distinct ecosystem. The lagoon is also divided into many small branches, connecting with rivers, canals, and wetlands, creating a vast and magnificent natural landscape.

Lagoon History – Witnesses of Time
In the 17th century, Tam Giang Lagoon served as a natural border between Dang Trong and Dang Ngoai during the Trinh-Nguyen War. During the Vietnam War, the lagoon was also a strategic area where many fierce battles took place. In 1975, during the final days of the war, this lagoon region witnessed major migrations of people leaving Hue. Today, the lagoon still carries historical marks, serving as a repository of memories from a bygone era, while witnessing the development and transformation of the Ancient Capital region.
