The section from La Muraz to Cruseille, passing through Le Sappey, and then the climb from Cruseille to La Croisette are really nice. Beautiful road, few cars and gentle slope!

Col de Croissette. What a beautiful tour. A long climb with percentages up to 18% brings you to the plateau of the mountain. There with rolling roads and paths towards the west to enter the descent and via the North back to Geneva.

The climb via Collonges sous Salève is the hardest. With slopes averaging 10-11%. Easier on the La Muraz side. The climbs are well shaded. Good surface. Lots of cars on weekends.
