To reach the car park, drive through Château-Bas in the municipality of Tréminis, then leave the D216 further on at a bend and take the road on the right with wooden signs indicating Col de la Croix, among other destinations.
Park in the Girardère car park (not marked), in a clearing after a small bridge.
(D:A) Continue along the wide track. Very soon, you will see a forest hut on your left and a large information board marking the start of the Resistance trail. Then reach the Grand Ferrand picnic area. Continue straight ahead and you will come to a crossroads of trails at a ford.
(1) Cross the river via this ford, take the path on the left and continue along the wide, well-marked path, signposted in yellow. Then climb steadily through the woods, sometimes quite steeply, and reach the junction with a track at Les Fontettes.
(2) Take the track on the right, pass by the Fontaine des Bœufs, then arrive near the Refuge du Col de la Croix before reaching the multiple crossroads at the Col de la Croix. Enjoy the magnificent panorama of the Grand Ferrand and the Dévoluy.
(3) Take the track on the right and reach the site of the old lithographic quarries.
(4) Cross the fence on the left and climb up through the meadows. Reach the ridge and the cross. Enjoy the panoramic view of Dévoluy, Vallon de la Jarjatte and Rocher Rond.
(5) Descend as you can see to the previous crossroads.
(4) Take the track on the left to reach the signpost for L'Alpage de la Paille.
(6) Take the path through the meadows, which is easy to spot thanks to the very tall fluorescent yellow posts or wooden poles with yellow paint at the top.
Pass by the old sheepfold (signpost and information board) and, shortly afterwards, reach the edge of the woods.
(7) Enter the woods and continue along a very pleasant path. Descend rapidly through the undergrowth. The path is sometimes narrow and steep but not difficult, and a secure metal staircase makes it easy to cross the rocky part of the terrain. You will reach the Amigoni stele fixed to a tree.
(8) Continue downhill on the right. After the fords, turn right until you reach the track and turn right again to return to the Girardière car park (S/E).
