Park in the car park of the community hall at the exit of Saint-Julien-en-Beauchêne in the direction of the former Chartreuse de Durbon.
(S/E) Return to the tarmac road and turn left at the first crossroads. Cross part of a housing estate and turn right, continuing for about a hundred metres.
(1) The trail starts heading north and quickly climbs through the boxwood trees (this is the steepest part). After a few switchbacks, it veers northeast. Stay on the main path, ignoring the various turnoffs on the left, and you will come out onto the vast Pra Pinet plateau.
(2) Continue to the right along a forest track. Continue for about 500 metres.
(3) At the second sign, turn left towards Col de Guillotier. The path winds through scree and a beech forest (the leaves cover the stones, so take care). After about 1,500 metres, you will reach Col de Guillotier (1,403 metres).
(4) The trail continues towards Col du Pendu, but we are on the north-facing slope and the trail is a little wetter. Join a forest track and follow it for about 300 metres.
(5) Leave the track and turn right (signposted) onto the path leading to Col du Pendu.
(6) At the pass, turn right onto theGR®94C(white and red markings) which leads to the old Chartreuse de Durbon.
(7) Follow the beautiful path above the monastery (GR®).
(8) If there is no one around, take a quick look at the Cros holiday centre (private property) to avoid disturbing anyone. The view of the Penne cliff is spectacular. After about 300 metres, turn left onto theGR® trail, pass the Maison Forestière des Étroits and join a tarmac road.
(9) Turn right onto this road, which will take you back to the car park (S/E).
