The Gave d'Ossau and the Gave d'Aspe meet to form the Gave d'Oloron.

It is formed in Gabas from the confluence of two gaves coming from both sides of the Pic du Midi d'Ossau:

  • the Gave de Bious, from the Pic d'Astu (west)
  • the Gave du Brousset, from the Anéou Circus (east).

After joining the Gave d'Aspe, in Oloron-Sainte-Marie, it forms the Gave d'Oloron. It is considered the upper course of the Gave d'Oloron by Sandre.[1]

Throughout its length, the river is paralleled by the D934 road that runs from Pau to Spain, via the Col du Pourtalet.

In Castet, a dam forms the Lac de Castet.
