The river originates in the small Lake Lavant (Lavantsee) at the southern slope of the Zirbitzkogel mountain in Styria, at a height of 2,053 m (6,736 ft). It then runs southeastwards and after 11.2 kilometres (7.0 mi) reaches the border with Carinthia. The river flows down the Lavanttal with the towns of Bad Sankt Leonhard, Wolfsberg and Sankt Andrä, until it reaches the Drava shortly before it crosses the border to Slovenia.
The water quality has been affected by large-scale river regulations between the 1930s and 1980s. Most parts of the Lavant belong to the trout zone, while the lowest sections are characterised by barbels.
