The Naxçıvançay rises on the northeast slope of the Keçəldağ Mountain , at the interface between the Ajozdsorski Mountains in the west and the Sangesurkamm in the east. The river initially flows in a southerly direction, later in a southwesterly direction from the mountainous region. He passes the Şahbuz Rayon Administrative Center and picks up Kükü from the right.

Shortly thereafter, the Naxçıvançay changes direction and flows the rest of the way south. The Cəhriçay , the largest tributary of the Naxçıvançay, flows into the river on the right. Later the Naxçıvançay flows through the republic capital Naxçıvan , passes the district administrative center Babək and finally reaches the north bank of the Aras reservoir .
