At the town of Višegrad, the Drina receives the Rzav River from the right and turns northwest at the Suva Gora mountain into the Klotijevac gorge. The gorge is long and up to 1 km (3,200 ft) deep, carved between the mountains of Bokšanica (from the west) and Zvijezda (from the east). The villages of Sase, Resnik, Đurevići and Gornje Štitarevo lie in the gorge and the Kukal river flows into the Drina from the right. At the Slap village, the Drina receives the Žepa river from the right and turns sharply to the west, becoming a border river between Bosnia and Herzegovina and Serbia near the village of Jagoštica.
