To reach the starting point, after passing through the village of Saint-Mathieu, follow the Cami de Lou Castellas which leads to the Ermitage du Pic Saint-Loup wine estate. Before the gate, turn right onto the track. The car park is located 100 m further on.
(S/E) Take the red and white marked trail that climbs south-west; this is the GR®60.
(1) Just before the reservoirs, climb up to the right, following the yellow markings. Continue along the marked trail. A little further up, you will come to a viewpoint overlooking the Château de Montferrand and the summit of Pic Saint-Loup. Continue along the GR®.
(2) Continue straight ahead on theGR® trail, passing a sign on your right prohibiting access to the castle grounds.
(3) From the Pas de la Pousterle, continue straight ahead to the next crossroads.
(4) This crossroads is not very visible, but a path leads into the woods on the right towards the ridge. This entire section up to the summit is quite tricky, as the path is narrow and fairly steep, following the ridge to the top. It offers beautiful views but requires the use of your hands. This section may be difficult for those prone to vertigo.
As it follows the ridge, there is little risk of getting lost, but the markings are fairly sparse. They are sometimes blue and sometimes green, but they are quite old and therefore not very visible.
Alternative route: At this point (4), you can also continue straight ahead on theGR® to climb up to the peak via the point.
(5) As you approach the peak, you will meet up with all the hikers who have climbed via theGR®. From this point, descend via the GR®.
(6) At the Croisette crossroads, turn right and continue downhill on a wide path.
(7) A small cairn marks this intersection. Leave the main path by turning right and continue downhill on a small trail.
(8) At the entrance to Cazevieiille, you will find yourself on a tarmac road. Take this road on the right for about 50 metres to start climbing again. You will pass some ruined towers.
(9) Afterwards, keep an eye out for the path heading due north. Another orange-marked path, the one we took, leads into the woods and is a little longer, but the trail returns to the route. Continue climbing until you reach a small pass that allows you to change slopes and then descend.
(10) Leave the path coming from the left and head east, the aim being to follow and remain parallel to the massif.
(11) At the Y-junction, go right.
(12) At the end of a clearing, descend (be careful in this section as there are many paths; keep heading east, even if the trail zigzags at times).
(13) Three-quarters of the way down a fairly steep ravine, turn right to climb back up to the Pas de la Pousterle.
(3) You will rejoin theGR® trail you took on the way up. Take it to the left, in the opposite direction.
(2) You will find the path leading to the castle on the left. Access is permitted, but entering the grounds is prohibited.
(14) From Montferrand Castle, stay outside the fences and go around it. Then head south. The descent is quite steep. Follow the red markings until you reach a wide path.
(15) Turn right onto a wide path to reach the car park (S/E).
Some sections are vertiginous, see reviews
