Stung Treng, a northern province of Cambodia, is a land of rivers, history, and natural beauty. Once known as Xieng Teng, the region has shifted between empires and kingdoms over the centuries. It was once part of the Khmer Empire before being absorbed into the Lao kingdom of Lan Xang, then into the Lao kingdom of Champassack, and finally ceded back to Cambodia during the French Indochina period. 

This layered history has left Stung Treng with a unique cultural character, blending Khmer and Lao traditions in daily life.Today, the provincial capital, also called Stung Treng, serves as an important trading hub. Just 50 kilometers from the Lao border, the town reflects its position as a crossroads of cultures. 

Situated on the banks of the San River, where it joins the mighty Mekong, Stung Treng offers travelers a peaceful riverside setting, a relaxed pace of life, and subtle touches of Lao influence alongside Khmer heritage.

The Irrawaddy Dolphins

Among Stung Treng’s most iconic attractions is the freshwater Irrawaddy dolphin, a critically endangered species that inhabits stretches of the Mekong River between Stung Treng and Kratie. With only about 40–60 individuals remaining, seeing these dolphins in the wild is a rare privilege

These dolphins are usually spotted in small groups of 6 to 10, surfacing gracefully in the early morning or at sunset. Adults can grow over 2.5 meters in length and weigh up to 180 kilograms, while newborns, typically born between June and August, measure about 1 meter long. Feeding primarily on fish, shellfish, and snails, they are strong swimmers capable of speeds up to 40 km/h and can remain submerged for 5–10 minutes at a time.

Conservation & Habitat

The Irrawaddy dolphin faces serious threats from entanglement in fishing nets, habitat degradation, and illegal practices along the Mekong. To protect them, the Cambodian government and WWF-Cambodia have established conservation zones, promoted sustainable fishing, and launched awareness campaigns. Travelers who visit these areas contribute directly to the survival of this species, as responsible ecotourism supports both dolphin protection and local livelihoods.
