Indeed, its position overlooking Lake Gentau (the most famous of the 6 lakes of Ayous) makes it an idyllic lookout on the Pic du Midi in Ossau. We accelerate the pace and quickly reach our cozy nest one night, perched in the mountains. Local beer to celebrate this first stage!
The burning lights of the sunset glide on the Pic d-Ossau. The horses in freedom sail peacefully along Lake Gentau. Everything goes in silence. We are as absorbed by this painting made in Pyrenees.
