Leaving the Aspe valley by the vertiginous Chemin de la Mâture you will rise through forests and estives to the Ayous pass to enjoy an exceptional panorama of the fascinating Pic du Midi d'Ossau. The descent into the Ossau valley is lined with magnificent lakes. A well-marked itinerary, for experienced walkers and in good weather.
