The river continues to the north, almost in a straight line, parallel to the Serbian-Bulgarian border on the east, and the eastern slopes of the mountain Tupižnica, on the west.

It is generally considered that from this point, the Timok Valley region begins.

The river passes through Gornje Zuniče, Donje Zuniče, Debelica, Trnovac, Minićevo, Drenovac, Selačka, Mali Izvor, Borovac, Vratarnica, and Grljan.

A few kilometers after Grljan, the river reaches the largest city on its course, Zaječar.
