Settlements

The largest town on the river is Dačice. The river flows past the municipalities of Panenská Rozsíčka, Bezděkov, Sedlejov, Urbanov, Žatec, Dyjice, Radkov and Černíč in the Vysočina Region, then it continues past Dačice, Cizkrajov, Staré Hobzí and Písečné in the South Bohemian Region before crossing the border into Austria.

In Austria, it enters the Raabs an der Thaya municipality and flows to the town proper of Raabs an der Thaya, where it joins the German Thaya. From there, the unified Thaya river flows generally eastward and re-enters the Czech Republic.
