Situated at the feet of the Pyrénées, 50 km from the Spanish border and 100 km from the Atlantic ocean, Oloron-Sainte-Marie is at the confluence of two gaves (mountain rivers), the Gave d'Aspe and the Gave d'Ossau that merge to form the gave d'Oloron. Capital of the Haut-Béarn, Oloron-Sainte-Marie is also at the point of origin of the three Haut-Béarn valleys : the Aspe Valley, the Ossau Valley and the Barétous Valley.
