Description of the walk

Coming from Barcelonnette via the D902, follow signs for “Col de la Cayolle”, which are clearly marked on the road signs. At the pass, there’s a large car park.
On that particular day, the large car park was full, so we turned back and parked further down the road at the side of the carriageway.

(S/E) Walk up towards the Col de la Petite Cayolle for a few dozen metres, then take the path on the right (GR®®56BTour du Haut Verdon). Take a good look around you, as you’re being watched. Indeed, there are marmots everywhere in this lovely meadow, which we’ll follow for about 2,000 metres to pass close to a first (unnamed) lake.

(1) From there, tackle the climb up a scree slope with some lovely ledge sections.

(2) Cross the Col de la Petite Cayolle to reach Lac de la Petite Cayolle.
Arriving at the lake around midday, you can do as we did and have lunch on the snowfield below – it’s superb. We spotted a marmot emerging from under the ice. That creature certainly isn’t cold...

(3) From the lake, head back up the path to the pass.

(2) Take the path on the right which passes beneath the Sommet des Garrets, rising to 2,822 m, and you’ll easily reach Lac des Garrets 900 m further on.

(4) Look to your left – if you’re lucky, you might spot some chamois on the ridge.

To spice up the walk a bit, we went along the ridges to the right of the lake, but there’s a good path to the left as well.
After a short climb, head down towards the “Pas du Lausson”.

(5) Take the path on the left which leads down and takes you back to the car park where you started.
Before heading down, if you continue along this same path for about 250 metres towards the Montagne de l’Avalanche, you’ll enjoy a beautiful view of Lac d’Allos and pass a stone marker dating from 1823, which formerly marked the border between France and the Kingdom of Sardinia.

(6) When you reach the edge of the road, stay on the path that runs to the left of the last small lake.
All that remains is to find your car (S/E).

Notes

There are no drinking water sources along the route, but water runs everywhere (at your own risk).
I recommend wearing waterproof hiking boots and all the necessary rain and cold weather gear.
Don't forget your camera...

Worth a visit

Lac d'Allos. You can do this by extending the route, descending to Lac de la Petite Cayolle and climbing back up to Pas du Lausson. You can also get there from Allos, but be aware that in summer there is a charge for parking (7.5 euros as far as I remember).

A superb hike... Extraordinary views... we spotted marmots and ibex...
No problems with the signposting. The only slight annoyance... the final climb that brings the long descent to an end...

These lakes are magnificent and the easy route is fabulous, with marmots and ibex to be seen. The view over Lake Allos is splendid. Make sure you arrive early to get a space in the car park.

A lovely walk, particularly for the views from the Pas du Lausson – you can veer off the path slightly to enjoy the view of Lake Allos, or to climb up onto a ridge.
The description could have been a bit clearer.

A brilliant hike.
However, there was still some snow, so it was a bit tricky in places...
But apart from that, it was perfect.

A lovely walk; on 5 June, there was a fine snowfield to cross the Col de la Petite Cayolle, followed by pure delight at the lake of the same name, which was completely frozen over. Continue as suggested on the route to the top of the Lac d’Allos.
The return route via the Pas du Lausson can be tricky with young children
I’d recommend it...

A magnificent route, no great difficulty, to be done and redone, so much beauty in the landscapes, colours and lakes.
Be sure to read the recommendations and requirements to be observed in a national park.

A magnificent route with views of several peaks, including Pelat. Extraordinary views of Lake Allos. Encounter chamois, ibex and marmots preparing for hibernation.

A great little hike during which we saw lots of marmots, chamois and ibex. The lakes are magnificent, so don't hesitate to take the detour to see the view of Lake Allos

A superb walk, done on 16 September 2025, where every step is a feast for the eyes.
We took much longer than the estimated time because we wanted to enjoy this magnificent route to the fullest.
There was a gale-force wind from the Col de la Petite Cayolle to the Pas du Lausson, and at times we had to brace ourselves against the ground to keep our balance.
There were a few sections with scree, but they were not difficult.
We saw about fifteen ibex that let us approach them, chamois on the ridge and numerous marmots.
The lakes are splendid, set in magnificent surroundings.
Even though the descent may seem long, we were in no hurry to return to the starting point.

I went on this hike hoping to encounter rare wildlife, and I did: a whole family of ibex, marmots, birds and birds of prey, in perfect silence. It was just too good.

A magnificent hike, best done outside of peak periods due to the number of visitors.
A group of chamois was spotted just above the Petite Cayolle lake.
It's also worth climbing up to the promontory just before the Pas du Lausson to see Lake Allos.
Very beautiful scenery on the descent.

A beautiful hike with very rocky landscapes, very popular with families on Sundays. We were lucky enough to come across a herd of ibex at the Col de la Petite Cayolle. The lakes are low at the end of the season. Beautiful view of Lake Allos. The descent after the Pas du Lausson offers beautiful views of the surrounding peaks. The end of the hike through the larch forest before reaching the pass is magnificent.

A very beautiful hike passing close to two lakes, with stunning views of Lake Alos, then the option to climb to the summit of the mountain to enjoy magnificent panoramic views of the surrounding peaks
I recommend it
