View of the Verney and Grand Maison factories.

View of the Verney and Grand Maison factories. Water was also used to run the sawmills, of which there were 4. There was one in Oz, the Alex sawmill, which was destroyed in 1977 for the construction of the current dam.
You follow an almost flat path linking the Rivier d'Allemont, a small village at the end of the Eau d'Olle valley, from where a pipe appears in places on the path. This pipe arrives at the old Verney factory. At the place known as the weir you cross the bridge and observe the mountain carved out by the waters.
You go up into a mixed forest where many ungulates live: wild boar, deer, chamois, roe deer and ibex. This little frequented forest also sees the passage of the wolf, very present on the massif of Belledonne and Rissiou.

From here to the top of the itinerary, be vigilant. Chamois and ibexes take advantage of these quiet places to move upstream; it is not uncommon for them to move stones, and for them to fall! Stay on your guard, listen carefully for the sound of falling rocks.
