Loop to Col de la Colombière

This is a long, sustained mountain day that starts with the valley climb toward Thônes. You move through the busy town center and push deeper into the Aravis, where the gradients start to bite as you navigate the switchbacks toward Le Grand Bornand.The road steepens significantly above the village, where you weave through jagged limestone cliffs that funnel you toward the summit.

Once you reach the top, the descent toward Cluses drops is a rewarding and fast descent. From there you'll set direction to Sallanches where the final climbs awaits before you heading back towards the familiar road around the Lake of Annecy.
