The start of the walk is at the small car park by the Garlettes cemetery in Seyssins, accessible by bus via TAG network routes 19 and 21.
(S/E) Leave the car park, turn left and walk carefully along the D106d to the junction.
(1) At the junction, take the small road on the left for about 700 m, until you reach the hamlet of Les Fenouillères.
(2) Take a small road on the left called Chemin des Fenouillères, which becomes a track. Follow it to the hamlet of Cossey.
(3) Walk past the chapel, take Rue de la Pouya and follow it for about 200 m. Turn left onto Rue du Clot, cross Rue du Pré Balmet and take a path opposite which joins Route de Comboire.
(4) Cross this road, follow it to the right for about 50 metres, then turn left onto Chemin du Fort.
(5) Take the path on the right for 250 m and, at the fork (near a track), turn sharply left. The path begins the climb leading to the viewpoint (hiking signs present).
(6) Enjoy the view, then head north-east along a good path towards the ridge.
(7) Leave the track and continue in the same direction, follow the ridge and take the descent to a junction.
(8) Turn left onto the path that heads due south and climbs slightly. Follow it in the same direction for just over 1.5 km until you reach the small road leading to the fort.
(9) Take the road on the far right and head back down to the D106d.
(1) Follow it to the left until you reach the car park at the start (S/E).
