Col de la Perheux and the "Amis de la Nature" house

Go up towards Col de la Perheux for 1.3 km, along the tarmac road that continues as a forest path. You go past the farmhouse restaurant of the same name, before arriving 150 m further on at the Col. After admiring the view, take the hairpin bend to the right, then follow the markings(Chemin du Bas) for 1 km, until you get to the "Amis de la Nature" house.
