Parking on the Chemin Départemental 44E in Roquevaire.
(S/E) From the car park, continue along the road towards Lascour for 500 metres, where a sign on the left indicates "Grand Vallon par Esparet".
(1) Follow this direction to the left, walking alongside the properties until you see the first yellow markings.
Continue straight ahead towards the bottom of the valley, following the dry stream bed (ignore the yellow markings). This unmarked path continues to the Premières Roches, which you will pass using a cable lifeline.
Continue to reach the first potholes, which you will pass with the help of chains fixed to the walls.
(2) Leave a yellow-marked path climbing up to the right and continue straight ahead towards the bottom of the valley, passing near a cave below the path. After a few zigzags, you will find a yellowGR® path.
(3) At the first crossroads, turn left towards Puits de l'Aroumi. You will soon come to another crossroads. This time, turn right onto a small path that climbs steeply. Climb up to a signpost.
(4) Turn left and continue climbing gently until you reach a plateau (very nice view of the valley and the Garlaban). At the next junction, turn left again and start descending to join a yellowPR® trail. Follow this trail towards the Garlaban to reach the Source de Barquieu.
(5) Behind the spring, a path climbs straight up the scree, with a short section secured by cables, and then it's the final stretch to Garlaban (several paths lead there).
(6) To return, descend from Garlaban by taking the trails on the right, follow the yellow markings and return to the Source de Barquieu.
(5) From there, turn completely right onto the Dansaïres trail, which overlooks the Garlaban ravine and is protected by a large rock barrier.
Once at the bottom, you will find the car park (S/E).
