The start of this route is the spa resort of Uriage-les-Bains. Discovered by the Romans, it would have to wait for the 18th century for the unique properties of its water to be recognised.
Maybe take the opportunity to fill a water bottle. Although the Col du Luitel pass is difficult, it remains attractive.
To reach the pass the narrow road climbs continuously for about ten kilometres. But on arrival the view is a great reward.
Departing from Uriage-les-Bains, take the D524 towards Vaulnaveys-le-Haut, then Vaulnaveys-le-Bas until Vizille and its castle. Set off on the D1091 at the Péage de Vizille and carry on until Séchilienne, then turn left to take on the difficult climb of the Col du Luitel. When you arrive at the pass, turn right onto the D111 towards Roche-Beranger, Chamrousse le Recoin, and go back down after a break at the resort, towards Uriage-les-Bains via Séglières and St-Martin-d'Uriage.
Stunning views of Grenoble and its surroundings from Chamrousse, where Jean-Claude Killy won three gold medals in alpine skiing during the Olympic Games of 1968.
