Hiking
On the occasion of the Winter Olympic Games in Grenoble, which took place from February 6 to 18, 1968, a 18.3 km road with a height difference of approximately 1,200 meters was built to connect the Autrans plateau (where some events took place) and the Isère Valley via the villages of St-Quentin and then Toulaud. The route of this road then ended with an underground structure; the Mortier tunnel, 515 meters long and allowing passage under the cliffs of the Pointe de la Buffe.
