Route n°3 : This varied itinerary offers a wonderful foretaste of the mountain trails, ascending on the GR9 great hiking trail from the Tour sans Venin tower to take you close to the Trois Pucelles needles.
The descent via the old tramway line that once connected the Vercors plateau to Grenoble is worth discovering. Keep your eyes peeled in the tunnels.
Water available at JJ Rousseau Desert and Karl Marx Park.
