Description of the walk

(2) Turn right onto the refurbished trail in the mountain pasture. You will reach a new crossroads at a hairpin bend.

(3) Continue to the right to reach the first peak: Le Veyou (highest point).

(4) Descend along the ridge, then climb back up the ridge to the second peak: Le Signal.

(5) Begin another descent to Pas de Picourère and climb back up to the third peak: La Pelle or Roche Courbe.

(6) Descend via a redeveloped path to reach Col des Auberts and then theGR®®9crossroads.

(7) Turn right and walk uphill for about 20 metres to see the Rocher de la Laveuse (a hole in a rock offering a view of the village of Saillans). Then return to the previous junction.

(7) Take the path on the right, which becomes a forest track. Cross the Vèbre and arrive at the forest road. Continue left until you reach the Pré de l'Âne bend.

(8) Leave theGR®® and take thePR®® (sign) on the left to return via the mountain pasture to Pas de Siarra.

Notes

There is no water on this route.
Bring enough with you.
The Pas de Siarra trail was reopened in 2012 following major works. Closed since 2004 following two fatal accidents, it is now completely safe. For those taking children on this hike, it is still advisable to exercise extreme caution in the area leading up to the pass. A dry stone wall protects against the drop and the trail is wide at this point, but there should be no jostling as the fall would be fatal. Also be careful on the ridge section, as the cliff is particularly high.
One last point: the Pas de Siarra trail is off-limits to our fellow hikers: horse riders and mountain bikers.
Comments made by hikers who have completed this route and which deserve attention for future hikers: the trail is paved with steps, which are very tiring for the legs.

Please take care to respect the:
TEMPORARY QUIET ZONES IN THE SAOÛ FOREST between 15 May and 15 July 2025
WHY THIS MEASURE?
The establishment of these temporary quiet zones aims to preserve wildlife and its
habitats, particularly during critical periods. At the end of spring, chamois give birth
and are particularly vulnerable to disturbance. The females' food requirements
are increased: they must feed abundantly to prepare for and then ensure the suckling of
young. Human presence can cause stress and lead to young being abandoned. Faced
multiple pressures (hiking, presence of dogs, etc.), these zones offer a refuge for wildlife
wildlife by limiting disturbances from 15 May to 15 July. They are part of a management
of the Sensitive Natural Area, where the balance between preserving biodiversity
and human activities is a priority for the Department. Beyond the protection of
chamois, these areas benefit all wildlife species and help
maintaining ecosystem diversity. We invite you to adapt your practices by staying
outside these areas to limit your impact. These areas are monitored by
the Department's eco-guards who are present in the field and available to answer your
questions.
PRACTICAL INFORMATION
When? From 15 May to 15 July inclusive
Where? Between Pas de Floréal and Pas de Siara & Between Pas de la Motte and Passage de Picourère
How? By staying on the marked trails outside of temporary quiet zones.
Who is affected? Everyone!

Worth a visit

The Drôme Valley with its large towns of Crest, Saillans and Die.
The Saou forest.

Always be cautious and plan ahead when you're outdoors. Visorando and the author of this route cannot be held responsible for any accidents occurring on this route.

A beautiful sunny day 🌞 with views 😎 of snow-capped mountain ranges.
The climb, which starts from the Col de la Chaudière car park, allows you to warm up gently before arriving at Pas de Siara at 1,300 metres. Here, you will need to be patient as the steps break up the rhythm a little, but the views during the short breaks are well worth the effort and will keep you breathless as soon as you arrive at the first peak.
The picnic break is the icing on the cake! Enjoy Mother Nature.
The second and third peaks are just as surprising. The return route takes you through the forest to complete the circular loop and return to Pas de Siara before descending to the car park. Be careful ⚠️ and take care when descending.

A very beautiful hike. No particular difficulty. The trail has been improved and the climb to the first peak, Le Veyou, consists mainly of uneven steps. 360° view at the summit. A very beautiful hike. Don't forget to continue for about twenty metres to the Rocher de la Laveuse before descending towards the Pas de Siara after the last peak, Roche Courbe. No more patou on the horizon at this time of year.

The climb from the Col de la Chaudière is intense, so take your time. We did it in the mist. Once you reach the plateau, each peak has its own climb, so you can choose to stay on the plateau. But once the mist clears, the view is breathtaking. Everything is beautiful: the forest section, the views from each peak, the surrounding plains.

Hello, thank you for pointing out that parts of the description are crossed out. This was due to restrictions on access to this area between 15 May and 15 July, which is a protected area for chamois births.
It will probably be necessary to reposition this restriction each year.
Have a nice day

Very good hike, well marked, but be careful: some of the instructions are crossed out, but I didn't understand why because everything was fine for me.

The Trois Becs are truly magnificent! Extraordinary views! Picnic in the sun at the top of Le Signal. Please note that climbing Le Veyou from the Col de la Chaudière, with its thousands of steps, is not recommended for those with sensitive knees (especially on the way down). But the effort is well worth it.

It took us 6 hours and 40 minutes, including several breaks and a picnic. The return trip was quite difficult and tiring, but I was very satisfied with the hike. Very beautiful scenery

A very beautiful 360° walk across the three peaks (becs😀).
The return trip was a little less enjoyable as some sections were wider and less interesting

This Sunday, with a few drops of rain and some fog, we completed this hike. A very beautiful route, very well laid out. Access to the Pas de la Siarra has been made easier by the work carried out, with stones laid to simulate steps. There are still some difficult sections. Hiking poles are recommended.
The three peaks were accessible. The trail is very well marked.
Superb view over the Drôme valley and the Rhône.
It should be noted that hikers with their dogs angered a shepherd. We witnessed a Patou dog confronting a dog on a leash. The owners were forced to turn back.
Clearly informing visitors and "prohibiting dogs" after a clear sign at the Chaudière car park would be a plus to avoid this kind of situation.
Otherwise, it was a very beautiful and challenging hike with many families on the trail.

This hike is always enjoyable, with its breathtaking views.
Some friends from Brittany on holiday in the Drôme were blown away. We even got to see vultures dancing in the sky.
It was perfect!
