Long climb towards Europe's biggest dam. The closing kilometres in particular are pretty tough. Cycling on the dam itself is unfortunately prohibited. On foot or by lift are the only options.
Lange klim richting de grootste dam van Europa. Vooral de slotkilometers zijn behoorlijk pittig. Fietsen op de dam zelf is helaas verboden. Te voet of met de lift zijn de enige opties.
A must-see climb in the Valais!
A very long climb, during which it goes up without stopping for almost 25 km! The road is in very good condition throughout the climb, with very little traffic. The highest gradients are in the last part of the climb, where there are many tight switchbacks. Once at the top, it's worth having a lock (walking shoes) to take the path to the top of the dam, almost 300 metres higher (a cable car for this last leg is also available)
Montée incontournable du Valais !
Très longue ascension, durant laquelle ça monte sans arrêt durant presque 25 km ! La route est en très bon état tout au long de la montée, avec très peu de trafic. Les pourcentages les plus élevés sont dans la dernière partie de l'ascension, où se succèdent de nombreux lacets très serrés. Une fois en haut, cela vaut la peine d'avoir un cadenas (des chaussures de marche) pour prendre le sentier jusqu'au sommet du barrage, presque 300 mètres plus haut (un téléphérique pour cette dernière étape est aussi accessible)
