The Mekong River is one of the world's greatest river systems, serving as the biological and cultural lifeline of the Mekong Delta in Southern Vietnam. For local residents of the delta, this majestic river — known locally as the Cửu Long (Nine Dragons River) — is the sacred Mother River that brings fertile alluvial soil and sustains millions of lives.

1. Origin of the Mekong River
Originating from the perpetual glaciers of the Tibetan Plateau, the Mekong River flows southward, carving through deep canyons in China (where it is known as the Lancang River). It forms the natural borders of Myanmar, Laos, and Thailand, flows through the rich Tonle Sap basin in Cambodia, and splits into branches before entering Vietnam.
This 4,800 km journey hosts one of the most biodiverse river basins on Earth, second only to the Amazon River basin. It is home to thousands of endemic freshwater fish species and unique wetland vegetation.
2. The Legendary "Nine Dragons River" in Vietnam
As the Mekong enters Vietnam in An Giang province, it splits into two main rivers: the Tien River (Upper Mekong) and the Hau River (Lower Mekong). The river then branches out through a dense network of canals and empties into the East Sea through nine massive estuaries, earning the Vietnamese name Cửu Long (Nine Dragons):
- Tien River branches: Tieu, Dai, Ba Lai, Ham Luong, Co Chien, Cung Hau estuaries.
- Hau River branches: Dinh An, Tran De, Bassac estuaries.
Although environmental changes and dams have closed the Ba Lai and Bassac estuaries over time, the spiritual symbol of the Nine Dragons remains an immortal icon of the Mekong Delta culture.
3. Biological and Economic Lifeline of Southern Vietnam
The Mekong Delta is nourished by rich alluvial silt deposited over thousands of years. This sediment ensures bountiful rice crops, feeds natural shrimp ponds, and fattens the famous Nam Can mud crabs. The Mekong basin forms Vietnam's largest rice bowl and orchards orchard.
In Ca Mau, these river channels weave through protective mangrove forests. The annual floating season (from September to November) floods the plains with fresh water, bringing downstream migrating fish (like cá linh) and providing a harvest season for local fishermen.
4. Essential Mekong Waterway Experiences at Ba Ngoai Homestay

- Immerse in local eco-farming, catching river fish and grilling them on charcoal at our eco-huts at Ba Ngoai Homestay.
Frequently Asked Questions
How many active river mouths does the Mekong have in Vietnam today?
Originally, there were nine mouths. Today, due to sedimentation and dyke construction, only seven remain actively flowing to the sea (Ba Lai is dammed, and Bassac has silted up).
When is the best season to experience the Mekong River floodwaters?
The best time is the annual floating season (mùa nước nổi), spanning from September to November. The floodwaters bring rich alluvial silt, wild fish (cá linh), and beautiful wild water lilies.
