This 31 km loop offers breathtaking views and landscapes for the most courageous. With 2170 m of positive elevation gain and section close to 3000 m in altitude, you can admire the entire valley, as well as the many peaks and glaciers around you. The start of the route provides a good warm-up before tackling the climb to the Col du Bec des Bossons. From there, you will cross the high-altitude plateaus, where you will find the lake "Le Louché". The descent continues to "Le Pichioc" before ascending the final pass of the day. The final descent follows a very pleasant balcony trail before returning to your starting point.
