Popular with local professional riders because of the demanding nature of the 1,747m climb, the route is technically demanding, with lots of climbing. The climb starts sedately enough winding through vineyards but soon the road opens up to reveal alpine pastures and the Tsanfleuron glacier. The climb finishes with a glacier lake and dam 4km past the col.
