Kal-Koritnica stands on a sun-exposed terrace below Mount Svinjak to the northeast and above the confluence of the Soča and Koritnica rivers to the southwest. In addition to the village's double core of Kal (to the east) and Koritnica (to the west), it also contains the outlying hamlets of Pri Kukču, Čerče, Kolovrat, and Malnik (from north to south).
