Songkalia River (Thai: แม่น้ำซองกาเลีย) is a river in Kanchanaburi Province, Thailand. It joins with two other rivers, the Beak River and the Rantee River, at a point called Sam Sop or Sam Phrab in Sangkhlaburi District to form the Khwae Noi River.[1] "Song Ka Lia" in the Mon language means "over there".
It originates from Roki Creek in the forest of Thung Yai Naresuan on the west side. It flows through a meander in many Karen communities and villages. It is now popular as a destination for kayakers from Songkalia Bridge to Mon Bridge.[2]
