At the entrance to the village of Gresse-en-Vercors, coming from Monestier-de-Clermont, park in the car park on the edge of the CD8A, near the Chalet Hôtel Prayer.
(S/E) From the car park, follow the D8A north-east towards the cemetery.
(1) Opposite the cemetery, turn right onto the road towards the Serpaton mountain pasture. At the end of the road, take the track that climbs up to the left. Cross the stream and continue on the left towards Serpaton. When you reach the road from Uclaire, continue straight ahead to cross the barrier at the entrance to the Serpaton mountain pasture and continue for 200 metres.
(2) Take the track on the right for about 50 metres, then turn left to pass through the opening in the electric fence. Cross the mountain pasture towards the Croix de Gresse.
(3) At the cross, find the road leading to the antennas and follow it to the right until you reach the Serpaton antennas.
If there are cows in the mountain pasture, you can reach the antennas by staying on the road.
(4) Take the path (not shown on the map) that climbs to the right. Go through the opening in the fence and continue on the path towards the ridge. Pass close to the Croix de Saint-Paul and follow the ridge to the Rocher du Baconnet.
(5) At the top of Rocher du Baconnet (altitude 1,808 m), turn right onto the unmarked slope in the mountain pasture to join the balcony trail coming from Pas du Serpaton.
(6) Turn left onto the track. After 150 m, descend to the right across fields and off the trail to the Combe des Têtes towards the cross (elevation 1524 on the map).
(7) At the bottom of the valley (elevation 1,486), take the path on the right towards Uclaire. Join the road in a bend (elevation 1,361).
(8) Do not take this road, but turn left onto the path that descends. At the next intersection, turn right towards the hamlet of Uclaire. Return to the road and turn left.
(9) In Uclaire, look for the EDF transformer on your left, which marks the path to take that leads to the D8a at the Croix de Jean Moutet (elevation 1287).
(10) Cross the road with caution and take the wide track opposite.
(11) Turn right onto the path that takes you back to the centre of the village of Gresse-en-Vercors. Pass the town hall and the church to reach the car park where you started (S/E).
