Park atthe first car park in the village of Chichilianne, at La Richardière, past the cross-country ski centre, situated at 1,058 metres.
(S/E) Head towards Mont Aiguille and the Col de l’Aupet. To do this, at the first junction of forest tracks and roads, take the track on the right and immediately turn left onto the path at the bend.
This path soon joins a track that leads you to the start of a second path (altitude 1,190).
(1) From there, leave the track and take the path on the right, which will take you to the Col de l’Aupet in 1 hour.
(2) Once at the pass, the ridge path is opposite the pass’s summit, although a cross-shaped signpost indicates otherwise. Follow this well-marked path, which descends slightly before leading to the ascent of the Pas de Selle, where you’ll probably spot a few ibex. In a large scree slope – where high-top boots are recommended – follow the cairns to the left leading to the pass.
Please note: late-season snowfields can make it difficult to find your way and hinder progress: be careful and don’t hesitate to spend a few minutes going round them if necessary.
(3) At the pass (Pas de la Selle), follow the path furthest to the right, which leads to a superb viewpoint over the Queyrie plain (and its remarkable tree) and the Diois massif (Trois Becs, etc.).
From the pass, which isn’t very prominent, pass beneath the summit of Montaveilla, skirting it to the left.
(4) No hollowed-out tree trunks serving as drinking troughs (keeping slightly to the right). From there, begin the descent down the Plaine de la Queyrie and keep an eye out for the numerous marmots.
Please note: from the pass onwards, the elevation gain is minimal, the walking is easy but the distances are considerable.
(5) 200m past the striking tree on the Plaine de la Queyrie and before beginning the descent into the valley floor, don’t miss the old Roman quarry on the right. A fragment of a column marks its location; look up to spot the quarry and get a better view of it.
Following this delightful and unexpected discovery, continue the descent to the crossroads just before the Pré Peyret hut at an altitude of 1612 metres.
(6) Take the path on the left, leaving the hut straight ahead of you. Follow the path as it climbs gently and ignore the track branching off to the left.
At around 1620m, take the signposted path on the right, even though the IGN map indicates the path on the left (a minor error on the map, but the two paths join a few hundred metres further on).
At the point marked 1611, you’ll reach the sign for Pison, indicated as being at 1613m.
(7) Continue straight on, towards Chatillon en Diois/Archiane. You’ll reach the Col du Pison.
(8) Shortly after this pass, a path branches off to the left, marked by a cairn at its top.
Take this path and, once you reach the cairn, quickly note the Bergerie du Jas Neuf, which is on the route. Take in the views of the Vercors highlands and follow this well-marked path.
(9) Once you reach the sheepfold, keep heading in the same direction and ignore the first path branching off to the left. You’ll soon come to a second path which leads to the Cabane de Chaumailloux in 25 minutes.
(10) Magnificent views of Mont Aiguille. This hut has been renovated very recently and can accommodate up to 19 people, featuring a lovely wood-burning stove. Take a moment here to soak up the history of this place. Then continue towards the cave near the memorial, which is situated about 300 metres further on to the left.
(11) A unique story from the Vercors, with both a happy and a tragic ending, unfolded here. Return to the path and continue to the left to pass the Pas de l’Aiguille, then descend in about an hour to the car park where you started (S/E).
