Col du Glandon
D927Saint-Avre to Saint-Colomban-des-Villards
A wild, narrow climb in the Maurienne.
The D927 to the Col du Glandon at 1,924 m is a narrow, irregular climb through hamlets and high pasture in the Maurienne, twinned with the neighbouring Croix de Fer and a regular Tour de France test. Steep, tight and beautiful; mind the narrow upper ramps, the cattle, and the cyclists.
