The border starts in the west at the Georgian tripoint and proceeds in south-eastwards direction over various mountain ridges of the Caucasus Mountains, before turning to the north-east roughly halfway and then proceeding along the Samur river valley to the Samur Delta on the Caspian Sea coast. Mount Bazardüzü, the highest peak in both Dagestan and Azerbaijan, lies on the frontier. Parts of the border are fenced and equipped with technical facilities including barbed wire, sensors and cameras.
