The Yantra has its source from the northern foot of Hadzhi Dimitar Peak in Central Stara Planina, at 1,340 m (4,400 ft). In its upper course, it is alternatively known as Etar (Етър), its older name. The river flows into the Danube close to Svishtov.
The river characteristically forms a number of gorges as it flows northward through the foothills of Stara Planina. The most prominent and longest one is 7 km (4 mi), located close to the capital of the Second Bulgarian Empire Veliko Tarnovo.
