Col du Rosier
The eastern side of the Rosier is the classic way up and the toughest. It’s the shortest of the three options, but don’t let that fool you. This climb is long, winding, and in the forest. You’ll keep asking yourself if the top’s around the next bend.
The hardest part hits right at the base, with steep gradients that bite early. As soon as the road curves left, it settles into a steady rhythm all the way to the top.
