Course change
The Arros river starts, an altitude of 586 m (1,922.6 ft), in the Forêt des Baronnies, southeast of Bagnères-de-Bigorre, in the Esparros commune.[3] It then flows from south to north through the Hautes-Pyrénées department. It passes through the towns of Bourg-de-Bigorre, Tournay and Chelle-Debat. It gets in the Gers department and passes through the towns of Montégut-Arros and Villecomtal-sur-Arros.
About 4 km (2.5 mi) from Plaisance, the Arros joins, by its right side, the Adour river at an altitude of 113 m (370.7 ft).[4]
The Arros flows through 55 communes and two of them, both in the Gers department, have the name of the river: Montégut-Arros and Villecomtal-sur-Arros.
