Better known as the "Storms of the Bastille", gain altitude over the city of Grenoble. The start of the via ferrata is in the heart of the city, which makes it a charming route between mountain and civilization. The higher you climb, the more breathtaking the view will become. Finally, we offer ourselves a final in the foothills of the Bastille. The descent is made on foot in the Jardin des Dauphins. Count 3 hours.
