The river flows to the south and south-east, following the eastern edge of the Accursed Mountains, dividing them from the western region.

It receives many streams from the right, flowing down from the Accursed Mountains (most notably, Shlepica and Reqica), but the Erenik's major tributaries are from its western side (Trava and Lumbardhi i Lloqanit).

The river formed an epigene gallery feature called Ura e Fshejtë in the hill.

The river valley in this final section serves as a part of the route of the Peja-Gjakova-Prizren road.

The Erenik belongs to the Adriatic Sea drainage basin, draining an area of 516 km2 (199 sq mi).
