The Visok depression is located between Stara Planina to the north and the Vidlič (or Vidlich) mountain to the south. It is elongated (divided into upper and lower sections) and sparsely populated: the villages of Izatovci, Slavinja (where it receives the tributary of Rosomačka reka from the right), Visočka Ržana (where it receives the tributary of the Dojkinička reka, also from the right), Rsovci, Pakleštica, Velika Lukanja and former village of Zavoj, before it meets the Temštica.
