The Mother of Waters 

From China to Vietnam, the Mekong River is the lifeblood of Southeast Asia and offers a glimpse into the long history and diverse cultures of the region. The 12th longest river in the world and the 7th longest in Asia, it flows through six countries: China, Myanmar (Burma), Thailand, Laos, Cambodia, and Vietnam. As home to roughly 1,000 species of fish, 20,000 plant species, and hundreds of bird, reptile, and mammal species, the Mekong is one of the most biologically diverse areas in the world—second only to the Amazon River. See daily life come alive as you pass traditional villages, experience glorious sunsets, and learn about the activities, history, and cultures along this amazing river.

Watch and Learn About the Mekong River


The Mekong River connects six countries in Southeast Asia and flows through six distinct geographical regions, each with characteristic features of elevation, topography, and land cover. It originates on the Tibetan Plateau and flows down to the mountainous area through the Yunnan Province in the Hengduan Mountains. After leaving China, it forms the border between Laos and Myanmar (Burma) for roughly 62 miles. It then creates the border between Thailand and Laos, and flows east and south into Laos for roughly 250 miles. This stretch through Laos is characterized by gorges, rapids, and shallow depths during the dry season. It then marks the border between Thailand and Laos again before it passes through the capital of Laos. This is followed by a short stretch through Laos alone, including the region above Khone Falls, which are mostly too treacherous for river traffic.

Below Laos, it becomes much wider and before it crosses into Cambodia, the Mekong comes together with the Mun River. In Cambodia, it receives the Sap River and flows through the capital of Cambodia. As it goes into Vietnam, the Mekong slows and splits into smaller channels of the Mekong Delta. It finally discharges into the South China Sea. 


The Mekong River is steeped in a long history, and for thousands of years, it has been the lifeline of the populations that depend on it for survival. The earliest settlements along the river date to 2100 BC with the first recorded civilization—the Indianized-Khmer culture of Funan—dating to the 1st century. Excavations have uncovered coins from as far away as the Roman Empire. In the 5th century, the Khmer culture Chenla existed along the Mekong, and the Khmer empire of Angkor was the last great Indianized state in the region. Roughly 700 years ago, the Thai people escaped from South China across the Mekong to form the kingdom of Siam (now Thailand), and the Mekong protected Siam from invasions. The same ethnic group also settled in Laos.

In 1540, the Portuguese Antonio de Faria was the first European to discover the Mekong. Although Europeans showed only some interest in the Mekong, the Spaniards and Portuguese did launch some missionary and trade expeditions to the area, and the Dutch led an expedition up the Mekong in 1641-42. In the mid-19th century, the French led an exploration on the river between 1866 to 1868 and discovered that the Mekong had too many rapids and waterfalls to ever be useful for navigation. From 1893, the French enlarged their control of the river into Laos until the First and Second Indochina Wars ended French involvement in the region.

During the Vietnam War, the west bank of the Mekong provided a basis for raids against the advance of the communist armies in Laos. After the war, anti-communist forces fled west across the Mekong to refugee camps in northern Thailand. The tensions between the U.S.-backed Thai government and the new Communist governments in the other countries prohibited cooperation on the river's use.

The Mekong has long been regarded as the foundation of Southeast Asia's economic growth and prosperity—necessitating cooperation between the countries. In 1995, the "Agreement on the Cooperation for the Sustainable Development of the Mekong River Basin" signed by the governments of Cambodia, Laos, Thailand, and Vietnam formed the Mekong River Commission (MRC). The MRC facilitates joint management of the shared water resources and collaboration on development issues. In 1996, China and Burma became Dialogue Partners of the MRC.

Today, peace has returned to the Mekong, and much of it remains undeveloped and even unexplored. It is closely tied to the daily lives and culture of over 60 million people—people who depend on it for transportation as well as for water for cooking, irrigation, cleaning, and sanitation. For these 60 million—many of whom live in poverty—the fish and other resources in the river account for most of the protein in their diets and for their survival. However, life along the river is changing, as China has already constructed large dams on the river with plans for many more.


Cruise the massive Mekong Delta, which covers some 15,000 square miles. This picturesque area accounts for over half of Vietnam’s rice production, prompting it to be nicknamed the “rice bowl” of the country. One of the highlights is a visit to a local workshop to see how traditional candy and rice wine are made before sampling some yourself. Explore a colourful local market, visit a local sampan builder, and relish other fascinating activities. Explore French-influenced Phnom Penh, the spectacular Silver Pagoda, and learn about the sobering era of the Khmer Rouge regime. Interact with friendly Cambodian people at work and at play as you explore villages and visit with local schoolchildren, a skilled silversmith, and a farmer to learn about daily life today. You will also partake in a traditional water blessing ceremony with local area monks.

Beyond the Mekong, you can also explore great sights on land. In Ho Chi Minh City, enjoy a walking tour of the city’s highlights, partake in a cooking class, and visit the Cu Chi Tunnels, a network of tunnels used by the Viet Cong during the war. In charming Siem Reap, enjoy a traditional Apsara dance performance and explore the spectacular Angkor temple complex, whose architectural grandeur is arguably unmatched among the world’s ancient ruins. See a variety of temples, including spectacular Angkor Wat and the mesmerizing faces of Bayon. Researchers now believe Angkor was the largest preindustrial city in the world, and the remaining temples stand as a testament to the wealth and power of the Khmer Empire.
