The source of La Durance is on the northern slope of the Sommet des Anges, where the first small streams combine into a river.
This runs near to Montgenèvre and then flows into the larger Clarée river, and then passes through Briançon before the Guisane joins it.
It then continues south combining with the Gyronde  — the Écrins glacial stream — at L'Argentière-la-Bessée.
The confluence with the Guil occurs below Guillestre and Mont-Dauphin.
The Durance then flows south-south-west and flows into the Lac de Serre-Ponçon just downstream of Embrun.
The confluence with the Ubaye was flooded as the lake filled.
