The route starts from the car park at the school in Ongles.
(S/E) Take Chemin de la Peyroux, to the right of the oratory when facing it. At the next intersection, take the road on the left, which climbs slightly and curves to the right.
(1) At the three-way junction, take the left-hand road which descends and crosses a large farm.
(2) At the next crossroads (large hangar), continue straight ahead for 300 metres until you reach the Chapelle Notre-Dame (former parish church that once served the surrounding hamlets)
(3) Retrace your steps until you reach the previous junction.
(2) Follow the road on the left that climbs slightly towards the hamlet of Bouiron.
(4) In the hamlet, turn left onto the road that comes at a right angle. It quickly turns into a wide path that winds through fields, crosses a slightly wooded area, and eventually joins the D12 road that climbs to Lardiers (rubbish bins and signpost).
(5) Take the wide marked path on the right heading north towards Lardiers. It continues straight for 2 km through the forest, then through lavender fields and rejoins the D12.
(6) Cross the road and descend under the trees along a good path that immediately leads to the Grande Fontaine. The area is shady and cool, very pleasant in hot weather.
Then go back up the road and follow it until you reach Lardiers. This is a small, quiet village, typical of the Haut-Provence region. Its church is very old but closed. However, you can still admire its Romanesque portal, which is a treat for enthusiasts. Leave the village via the D12.
(7) Turn left onto a narrow road (hiking signs, orange and yellow/red markings). Pass the Chapelle Saint-Claude, built in the 17th century and rebuilt in the 18th century, and continue along this marked path, which eventually leaves the fields and climbs up a wooded hillside.
(8) At the crossroads at the top of the hill, leave theGRP® (red/yellow) and take the path on the right heading south. It quickly veers south-east and merges into a track. It then descends steeply, before levelling out as it heads south-west and joins a crossroads.
(9) Ignore the paths that lead off in all directions and keep going straight ahead. You will soon find yourself back in the woods and see the fields of the valley below. You will then come to the hamlet of Bouillon.
(4) Cross it to return to the crossroads you took on the way there.
(2) Take the road on the left to cross the large farm again, then climb back up to the village of Ongles (S/E).
