The permanent "Verticale du Grand Serre" course takes you from the village of Cholonge to the summit of Grand Serre—1,000 meters higher—via the most direct route: straight up.
Markers placed every 100 meters of vertical gain track your progress.
Come and train or prepare for the Verticale du Grand Serre event, which takes place in September.
