From Col des Planches, follow the road which descends in the direction of Martigny, then turn off to the left onto a forest trail which transports you into an enchanting landscape. The undulating trail will lead you to Alpage du Biolley where you can dine in summer.
During a gentle and shaded climb, you will pass by some mine carts from Mont Chemin. A little further on, take a few minutes to enjoy a pretty vantage point of Bovernier and Entremont.
After a short descent, the trail starts climbing in the direction of Col des Planches, passing through a charming little hamlet. From there, you only have one kilometre to go before returning to your starting point.
Comments: The trail is well-marked; follow the signs for the mountain bike trail “Les Planches n°778”
