Park in the Bellevue ponds car park, 800 m from the southern entrance to Peyrins, on the Mours à Romans road, alongside the D538.
(S/E) Walk along the football pitch and the sandy beach volleyball courts to return to the road (Rue de Salimard). Continue straight ahead and you will come to a crossroads on the access road to the château, which you can see on your left. Continue straight ahead (Chemin du Bateau), ignoring the paths on the right, and walk along a field on your left until you reach the corner.
(1) Take the path that branches off to the left despite the two Yellow Crosses and Red Crosses, and cross the stream (La Savasse). At the small building, continue straight ahead on the narrow path or take a slight left onto a parallel path to reach the Génissieux-Peyrins road (D112) at a large White Cross.
(2) Cross carefully and take the Chemin de Montachard opposite. Continue straight ahead for about 1 km until you reach a crossroads at the top of the hill.
(3) Turn sharply right onto Chemin des Échelles, which is tarmac for a few hundred metres before becoming a wide dirt track. Negotiate a 90° left turn at the corner of a meadow onto the track, which now becomes sandy, and continue for about 100 metres.
(4) Leave the road and take a path that branches off to the right. Climb gradually up this path, then turn right then left at a field of truffle oaks. Walk past a house and you will come to a crossroads.
(5) Turn left onto Route de la Feyta and keep right at the three-way junction. Continue along the road, ignoring the paths on either side, until you reach the junction with Route de Pianières.
(6) Turn left then right to reach the hamlet of Saint-Ange: panoramic view and chapel.
(7) Before reaching the chapel, find a steep path on the right that joins Route des Pianières.
(8) Continue left until the next crossroads.
(9) Ignore all of them and take the path that climbs diagonally opposite, lined with wooden posts and barbed wire. When you reach the intersection at the top of the climb, follow the path on the left.On the left, enjoy the view of the village of Geyssans, which is built on several levels, and as you continue, enjoy the view to the east of the Vercors ridges with the Grande Moucherolle and Veymont. Take the left again at the fork in the descent and follow the wide path that leads to a long building with a green roof.
(10) Turn right just before this building. Pass a metal shed and 100 metres further on, ignore the path that descends to the left towards the crops (apricot orchard or holm oaks). Continue for about 20 metres.
(11) Be careful not to miss the small path that descends to the left between oak trees (fluorescent orange markings). Quickly cross a path and continue straight ahead, following the fluorescent orange markings on the oak trees. Descend this path, which winds through the woods, staying on the main trail and ignoring any small paths that may branch off to the right or left. You will come out onto a small road called Chemin du Ravi.
(12) Turn left and follow it to the crossroads just before the ford on the Savasse.
(13) Turn right without crossing it and continue to the road coming from Peyrins (D112).
(14) Cross the bridge carefully, then turn immediately right onto Chemin des Blaches.
(15) Once you reach the hamlet, continue straight ahead to join Chemin du Bateau and the fork you passed on the way there.
(1) Continue straight ahead, following the outward route in the opposite direction to return to the car park (S/E).
