The source is near the Schöpfl (893 m) in the Vienna Woods. The source streams are the Riesenbach, Lammeraubach, Agsbach, Hainbach and the Großkrottenbach which all confluence at Klausen-Leopoldsdorf forming the Schwechat. It flows through the small town Alland, through the Helenental to Baden and through the Vienna Basin to Schwechat, where the river ends in the Danube.
The Helenental is the Schwechat's valley from Mayerling to Baden, named for the parish church of St Helena (Pfarrkirche St Helena) about 2 miles (3 km) from the town center of Baden. Originally gothic, it's since been replaced by a baroque structure.
