It heads first southwestwards and describes a wide arch bending westwards and northwestwards while still in its upper reaches. Then it heads roughly northwards all along its course. In its last stretch it bends northwestwards and joins the left bank of the Kulanotpes. The border of Korgalzhyn District, Akmola Region, stretches along the opposite bank.The river valley is wide and its channel is bound by steep banks. In the summer the Sonaly usually stops flowing and splits into disconnected pools.
