Geography
The Adour river has a length of 309 kilometres (192 miles).[1][N 1] Its drainage basin has an area of approximately 16,912 square kilometres (6,530 square miles).
Course
The Adour river starts, as Adour de Payolle, at the north side of the Arbizon mountain. This river combines with the Adour de Gripp and the Adour de Lesponne to form the Adour river at Campan.
The Adour flows north for almost 160 kilometres (100 miles) through the Hautes-Pyrénées to Gers. There, it turns to the west and gets into the Landes department. In Port-de-Lanne, the Adour is joined by the Gaves réunis river. Finally, it flows into the Bay of Biscay, in the Atlantic Ocean, between Anglet (Pyrénées-Atlantiques) and Tarnos (Landes).
Boats can travel on the river beginning about 72 kilometres (45 miles) from its mouth.
