Access the start point via the D280 from Sainte-Agnès or Prabert. Park at the Col des Mouilles car park.
(S/E) Take the main tarmac road, running perpendicular to the D280.
(1) At the main junction, continue along the road on the left, which becomes a wide track. Admire the views of Belledonne: Prabert, Prapoutel, the Cime de la Jasse and the Grand Ferrouillet.
(2) Leave the main track and take a path on the right (yellow signposts) towards Les Chères. Steep slope!
(3) When you reach a large clearing, take a wide track right at the very far end. From here on, the circular route is all downhill. Further on, ignore another track branching off to the left and keep to the right, continuing downhill to the Pré Marcel chalet.
(4) Join the road by veering slightly to the right 100 m after the chalet. Head back down the small tarmac road opposite the Chartreuse.
(1) At the junction, turn left and head for the Col des Mouilles (S/E).
