Where to practice an individual sport Entremont-Le-Vieux

The Granier mountain, or simply "Le Granier" for the friends. What a wonder! Iconic mountain of the Chartreuse massif, its 900 m high cliff, which follows the collapse in 1248 of its rock face, makes it recognizable among all. From the top you will have an incomparable view on the Chartreuse valley, the lake of Bourget and the Mont-Blanc. This difficult hike, a passage requires to cross small ladders, will cut you off from the world during nearly 3 hours of ascent. Be careful, the itinerary is not recommended when the snow is present.
