It takes its name from the city Pau, through which it flows. The word gave is a name given to rivers on the mountains in regions of the western Pyrenees; so, Gave de Pau means "the river of Pau" or "the river that flows through Pau". Many other rivers in the region have the word gave as part of their names.

Course

change

The Gave de Pau starts in the Cirque de Gavarnie, in the Parc national des Pyrénées ("Pyrénées National Park"), in the commune of Gavarnie, Hautes-Pyrénées department, at an altitude of about 2,600 m (8,530 ft).[3] The upper part of the river is known as Gave de Gavarnie; the name Gave de Pau is given to the river after the Gave de Gavarnie joins the Bastan river at Luz-Saint-Sauveur.

The Gave de Pau receives its main tributary, the Gave d'Oloron, in Peyrehorade and, from there, it is named as Gaves Réunis (United Gaves). Finally, it flows, as a left tributary, into the river Adour in the Landes department, at about 3 m (10 ft) of altitude.[4]

The Gave de Pau flows through 90 communes.[1] It passes through the following regions, departments and communes:
