Significant lowlands are to be found only near the coast, in the southwest near Arta and Preveza, in the Acheron plain between Paramythia and Fanari, between Igoumenitsa and Sagiada, and also near Saranda.
The main river flowing through Epirus is the Vjosë (Aoös in Greek), which flows in a northwesterly direction from the Pindus mountains in Greece to its mouth north of the Bay of Vlorë in Albania.
