Es genial poder subir este Puerto.... Paisaje que enamora.. Bastante buen asfalto y curvas de herradura. Un puerto que no es tan conocido pero que debes subir.

Busy ascent to Vex, then much quieter. After Les Collons, you can take the route to the mountain pastures.
More difficult in the 2nd part.

Montée fréquentée jusque Vex et ensuite bcp plus calme. Après les Collons, possiblité de passer par la route de l'alpage.
Plus difficile en 2e partie.

Goede weg met weinig verkeer. Goed te doseren als je weet hoe stijl hij is. Wegdek in top staat. Leuke verbogen klim
