The river flows NE to join the North Thompson after flowing generally east from Blue Lake, which is at a low pass with the basin of Murtle Lake and the Murtle River, which join the North Thompson via the Clearwater and the community of the same farther southwest. The Blue River forms part of the boundary between the Shuswap Highland (S) and the southwesternmost Cariboo Mountains (N).
