La vall\u00e9e d’Ossau est une vall\u00e9e des Pyr\u00e9n\u00e9es fran\u00e7aises, dans le d\u00e9partement des Pyr\u00e9n\u00e9es-Atlantiques en r\u00e9gion Aquitaine. La vall\u00e9e d’Ossau est une des trois grandes vall\u00e9es de montagne du B\u00e9arn. Elle s’\u00e9tire g\u00e9ographiquement du nord au sud sur une cinquantaine de kilom\u00e8tres depuis R\u00e9b\u00e9nacq (\u00e0 quinze kilom\u00e8tres de Pau) jusqu’au col du Pourtalet (\u00e0 la fronti\u00e8re espagnole). Elle est form\u00e9e de deux cantons : en partie basse vall\u00e9e se trouve le canton d’Arudy avec un paysage de pi\u00e9mont pyr\u00e9n\u00e9en. En partie haute-vall\u00e9e se trouve le canton de Laruns qui offre de la basse, de la moyenne et de la haute-montagne. Elle est travers\u00e9e par le gave d’Ossau et domin\u00e9e par le pic du Midi d’Ossau qui culmine \u00e0 2 884 m\u00e8tres.<\/p>\n
Situ\u00e9e en Haut-B\u00e9arn au sud de Pau, elle est parcourue par le gave d’Ossau, branche m\u00e8re du gave d’Oloron.<\/p>\n
C’est la plus orientale des trois principales vall\u00e9es b\u00e9arnaises creusant la cha\u00eene des Pyr\u00e9n\u00e9es. C’est aussi une vall\u00e9e glaciaire qui offre son embl\u00e8me \u00e0 la vall\u00e9e, \u00e0 la ville de Pau, \u00e0 la Section paloise : le pic du Midi d’Ossau. \u00c0 l’\u00e9poque glaciaire, le glacier s’\u00e9coulait jusqu’\u00e0 R\u00e9b\u00e9nacq, \u00e0 quelques kilom\u00e8tres au sud de Pau.<\/p>\n
Elle communique avec la vall\u00e9e de l’Ouzom et le Lavedan (Argel\u00e8s-Gazost), \u00e0 l’est, par le col d’Aubisque et avec l’Aragon, au sud, par le col du Pourtalet.<\/p>\n","url":"https:\/\/blog.elkami.fr\/category\/randonnees\/pyrenees\/ossau\/","hasPart":[{"@type":"BlogPosting","@id":"https:\/\/blog.elkami.fr\/col-de-peyrelue-par-le-gr108-a-compostelle\/","headline":"Col
