1. Col duGrand Cucheron
Located in the Belledonne massif, the Col du Grand Cucheron (1188 m altitude) links the Maurienne valley with the Vallée des Huiles.
From Aiguebelle, head towards Saint-Georges-des-Hurtières, then cross Saint-Alban-des-Hurtières before beginning the toughest part of the climb to the Col du Grand Cucheron. The last 5km at an average gradient of 9% are well worth the effort, but the breathtaking views over the Lauzière massif are well worth the diversions.
In the local vocabulary, the word Cucheron means mound, hill or rounded summit.
The Grand Cucheron was climbed by riders in the 1972, 1983, 1998 and 2012 Tours de France.
