Cả River, River system in Xiangkhouang Province, Laos and Nghe An Province, Vietnam.
The Ca River is a river system flowing from the mountains in Laos through northern Vietnam toward the sea. It travels about 512 kilometers, shaping the landscape as it passes through different provinces.
The river was formerly called Song Rung and served as an important connection between Laos and Vietnam for centuries. This role as a transport route long shaped economic development in the region.
Fishing communities along the river maintain traditional methods handed down through generations, keeping their customs alive. These practices continue to shape daily life on the banks.
The river has several crossing points, including the Ben Thuy Bridge near the mouth, which makes travel between regions easier. The best time to visit is outside the rainy season, when water levels are lower.
The river has different names depending on the country: Nam Khan in Laos and Song Ca in Vietnam, reflecting the region's linguistic diversity. These name differences show how borders and cultures exist side by side in this area.
