A sunny climate

Benefiting from a privileged climate because it is largely sunny and protected from western disturbances by the summit of Arbizon its guardian angel, the Aure valley is a pleasant place and preserved from industrial development. From the village of Arreau, it goes up and stretches along the river the Neste d’Aure to Spain, the access to which is through the Tunnel of Aragnouet-Bielsa.

In this valley, mainly pastoral, Saint-Lary developed rapidly in the post-war period, particularly with the construction of large hydroelectric dams at high altitudes such as the cap de long dam and the ski resort, the development of which began in 1957.

Near the Spanish border, the direct access to the Sobrarbe region in Aragon (thanks to the Bielsa tunnel) is also one of the assets related to our valley. This region is exceptional with a surprising geological heritage. Canyons and rivers compete in beauty.
