A 50k monster climb from Bourg Saint Maurice takes you to the summit at 2770m, making it one of the highest road passes in Europe.
Col de L’Iseran was first used in the Tour de France in 1938 and last appeared in 2007 with a stage that started in Val d’Isere which also included the Col du Télégraphe and Col du Galibier.
The climb takes you up past the huge dam on Lac du Chevril at Tignes and then passes through Val d’Isere where the road becomes much more quiet. A short drag and a right-hand turn takes you onto the top section of the climb which zig-zags it’s way up the mountain, delivering a breath-taking view back down the valley to Val d’Isere.
As you climb higher the gradient eases but the air gets thinner and the landscape takes on a very different feel which enhances the sensation of being at altitude. At times it really can seem other-worldly and very remote.
