A car park is signposted at the start of the walk, but there is little space: it is best to park at the town hall car park.
(S/E) Follow the road to the “P” sign / Haute-Provence Geological Reserve. Head up to the left onto a path, following the yellow markings. Although you’re on the edge of a housing estate, you’ll soon find yourself in the countryside, in the shade under the trees.
(1) Continue to the right and walk alongside the housing estate on your left. Just after this, turn onto the path on the right.
When you reach a flat area, walk past the Chapelle Saint-Jean (which you will see on the way back), turn right at the junction and head slightly downhill to reach a sandy area.
(2) Look out for the path on the left, which you will take on the way back, and continue straight on, starting to climb again. Pass an information board displaying fossils and carry on: some sections are steep but short, and the path climbs up to a lodge at the foot of the old village.
(3) Apart from the restored church, there is not much left of Old Aiglun. After going round the Church of Sainte-Marie-Madeleine and its esplanade, follow the path across a small meadow and head straight up the stony track. Further up, the path levels out: go straight on, pass the high-voltage power line to reach the highest point of Le Puy and enjoy the view.
(4) Retrace your steps, pass under the high-voltage power line again, then leave the path you took on the way up and head off to the right. Follow a wide track for a few metres, then quickly turn south onto a small path which, after a short flat section, descends rapidly.
(5) Just before the junction shown on the IGN map with a path branching off to the right, do not take the path that descends to the left (this path is not marked on IGN maps but is visible on OSM). Continue straight on towards a flat section where the junction shown on the IGN map is not (or barely) visible.
On this flat area, start to change direction by heading left onto a very slight uphill section before continuing the descent. Some sections are steep but short, and the view opens up towards Vieil Aiglun. Continue descending; at a T-junction, turn left and, at the exit of a hairpin bend, descend to the left at the Y-junction. Pass through a barrier to finally reach a gate.
(6) Continue straight on towards the hamlet of Le Roux, where you’ll reach a tarmac road. Head down to the right.
(7) Turn left onto the Voie des Genêts, staying on a short stretch of tarmac.
(8) When you reach the last houses, head down through the trees on the right, following the yellow markings until you rejoin the path you took on the way there.
(2) Head up to the right, then keep right again to reach the Chapelle Saint-Jean. Continue straight on, heading downhill and passing the water station on your left. Join the path you took on the way up again and follow it in the opposite direction.
(1) Cut straight across to reach a small street which leads further on to Rue des Pitchounets. Turn left to return to the car park (S/E).
