Les Cols Mythiques



A crossing point to the neighbouring Béarnaise Valley and the Aspe Valley, the Marie Blanque Pass is one of three must-see passes in the Ossau Valley.
Taking it from the village of Bielle, you will pass through the hilltop village of Bilhères en Ossau to the expanses of the Bénou plateau, a veritable haven of greenery and pastoralism, where you can admire a remarkable view of the entrance to the valley. Continue on your way and take the hairpin bends up to the pass. A must-see for cycling enthusiasts, at an altitude of 1,035 metres, it is a regular stage of the Tour de France and offers seasoned cyclists an exceptional 14% gradient.
Hiking enthusiasts will also find something to suit them!
From the pass, take the path to the Pic d'Escuret. From there, after a 1½-hour walk and perched at an altitude of 1,432 metres, you can enjoy a breathtaking 360° panorama of the Béarn foothills!

Heading towards the Spanish border, you will reach the Pourtalet Pass, a tourist route from France to Spain, from the Ossau Valley to the Tena Valley.
Located at an altitude of 1,792 metres, it offers an unmissable view of the Pic du Midi d'Ossau, which rises to 2,884 metres.
Close to the border, the protected area of the National Park awaits you. Covering an area of 8,800 km² in the valley, it is dominated by the Pic du Midi d'Ossau. At the heart of this protected area lies the Cirque d'Anéou.
A mecca for pastoralism, every summer it welcomes numerous herds to the mountain pastures known as ‘estives’.
For hiking enthusiasts, it is a real playground for reaching the high points of the Ossau Valley, such as the Pombie refuge or the Pic de Peyreget.
For cyclists, the Col du Pourtalet is one of the essential crossing points in the Ossau Valley, particularly during cross-border cycling races such as the Quebrantahuesos or the Vuelta.
