The car park at the start is at the end of the Chemin du Vallon des Escourtines (tarmac).
(S/E) At the far end of the car park, take the valley path that leads into the forest. After about 800 m, you will reach a crossroads.
(1) Leave the return path on your left and continue rightwards into the valley (GR®2013). After about 500 m, at the junction, keep left, leaving the GR®, and rejoin it a few hundred metres further on. Continue for about 100 metres to the next junction.
(2) Leave the GR® which heads off to the right and continue the climb towards the south-west. The path then turns south and then south-east, reaching a fork at an unnamed pass.
(3) Head right for about 350 m towards Mont Lantin. Reach a fork.
(4) Ignore the path branching off to the left. Continue the ascent to the fork below the summit:see § Practical Information.
(5) Take the slightly less marked path branching off to the left and continue for about 250 m.
(6) Take the path branching off to the right. Climb over a rocky outcrop to reach Mont Lantin, marked by a large cairn.
(7) Enjoy the exceptional view. Begin the descent along the path heading east and return to the fork you passed on the way up.
(5) Continue down the path you took on the way up until you reach the unnamed pass.
(3) Leave the path you took on the way up to your left and continue straight on towards the secondary summit of Mont Lantin (elevation 504m), marked by a cairn at its summit. Continue descending along the north-western ridge until you reach a crossroads with paths leading in several directions.
(8) Ignore the path on the right leading into the Vallon des Quarres. Further on, ignore the path branching left towards another valley and head straight on (east) along the track which, further on, runs alongside a power line. After a few hundred metres, pass underneath it and join a track (elevation 354).
(9) Turn left onto this track and continue for just over a hundred metres to rejoin the GR®2013.
(10) Leave the path that branches off to the left and continue straight ahead, passing under a power line and joining a small path that branches off to the left.
(11) Leave the GR® which continues eastwards and take this path which climbs through the trees and turns sharply left. Pass under the power line and reach a fork (elevation 396).
(12) Turn right again onto the GR®2013 until you reach another fork.
(13) Turn right (north), still on the GR®, until you reach a nearby junction.
(14) Ignore a path leading down to the right towards La Penne-sur-Huveaune and stay on the GR®, which turns left towards the Vallon des Escourtines. Return to the original fork.
(1) Take the path on the right into the Vallon des Escourtines and follow the route back along the same path to reach the car park (S/E).
