Geography

The river is sourced from above the hamlet of Plaine Dranse [fr], in the commune of Châtel near the pointe de Chésery and the Franco-Swiss border, in the Chablais.

It irrigates the Val d'Abondance.

In Bioge (a commune of Reyvroz), the river joins the Dranse at the confluence with Dranse de Morzine, which empties into Lake Geneva in the Delta de la Dranse National Nature Reserve between Thonon-les-Bains and Évian-les-Bains.
