The Drava flows through San Candido/Innichen in Italy, Lienz, Spittal an der Drau, Villach, Dieschitz and Ferlach in Austria, Dravograd, Vuzenica, Muta, Ruše, Maribor, Ptuj, and Ormož in Slovenia, Varaždin and Osijek in Croatia, and Barcs in Hungary. The Drava is navigable for about 90 km from Čađavica in Croatia to its outfall.
The main tributaries of the Drava are: the Gail in Austria, the Meža and Dravinja in Slovenia, and the Bednja in Croatia from the right; the Gurk and the Lavant in Austria, and the Mura (near Legrad) in Croatia from the left.
In the ancient times the river was called Dravus. The name is most likely Celtic or pre-Celtic in origin (see Old European hydronymy).
