Kong River

The Kong River is a river in Southeast Asia that is also known as the Xe Kong or the Se Kong. The river begins in Central Vietnam's Thừa Thiên–Huế Province and flows 480 kilometers (300 miles) through southern Laos and eastern Cambodia. It flows into the Mekong River near the Cambodian town of Stung Treng. A portion of its path forms the international border between Laos and Cambodia.

The Xe Kaman River is its tributary that flows through southeastern Laos. It runs through Attapeu Province's Dong Ampham National Biodiversity Conservation Area. Dolphin populations are known to exist in the river. A dam being built on the river is destroying the area. The village of Ban Hin Dam is located on the river and serves as the starting point for boat trips.
