Description of the walk

At La Roche-de-Rame, take the track (signposted Le Lauzet) and park in this hamlet.

(S/E) Cross the Torrent de Bouchouse on the footbridge and immediately turn left onto the wide track leading to the ruins of Le Giet, as marked on the map, which are now beautiful chalets. Continue along this track, ignoring the wide path on the right, to reach the Rocher Rouge crossroads.

(1) Take the beautiful path on the right (signposted Lac de l'Ascension). Quickly begin a steep descent ending at the crossroads of the path leading up to La Roche-de-Rame, at a place called La Chapelle.

(2) Continue straight ahead and then tackle a long, dry but pleasant climb away from the right bank of the Torrent de l'Ascension. Pass a very pleasant rocky outcrop to reach the Chalet de l'Ausselard or Alpavin.

(3) Continue the climb, crossing a few mini sharp limestone pavements to reach the large mountain pasture before the lake, then climb the last hill to reach Lac de l'Ascension.

(4) Continue along the only visible path, then reach the two other lakes: first the Escur and further on the Petit Lac Escur. Further south, begin the climb up the clearly visible small pass Collet du Peyron and reach the pass.

(5) Begin the descent with caution as the slope is relatively steep and the small stones covering the ground can cause falls. After a rocky section, reach the mountain pasture where the path becomes much more pleasant. You will come to a crossroads.

(6) Take the path on the left that remains in the mountain pasture; it is marked with cairns. You will reach the edge of the Font des Ardouis ravine. Continue to the left of this ravine, following the cairns and the very discreet yellow markings. You will then enter the forest, where the path (which is rarely used) becomes less obvious. Keep an eye out for the cairns to find your way. You will come to a yellow arrow on a rock (this arrow points upwards).

(7) Turn right, find a yellow mark on a stone, continue on level ground to find a good path marked with fluorescent orange markings (trail-type markings). Stay on this good path to reach the ruins of Les Ducs (these are real ruins).

(8) Continue downhill, cross the Torrent de Bouchouse, and join the track leading to the hamlet of Cougnet.

(9) Take it on the right to reach the hamlet of Lauzet and the car park (S/E)

Notes

Take enough water with you as there are no springs on the circuit (see the chalet if necessary).
There is no shelter, but in good weather the area around the lakes offers interesting places to stop for a break.
Please note: From (6), the route described is only suitable for experienced hikers who are confident in finding their way. For those who are less sure-footed, it is advisable to follow the path on the right, which is much more well-trodden and leads back to Le Giet and then along the track to Le Lauzet.

Worth a visit

The Durance valley and its adjacent valleys are dotted with pine woods:
- Opposite La Roche-de-Rame, the Freissinières Valley,
- At L'Argentière, the Vallouise Valley and Pelvoux, ending at Pré de Madame Carle at the foot of the Blanc and Noir glaciers.
- Higher up, Briançon and the Guisane and Clarée valleys, and towards the Italian border, the Durance valley.

The length of the drive on a rough road probably discourages some people and guarantees a hike without crowds, which is great! It's beautiful and varied. The Viso Rando app was invaluable on the last part of the route, as the track had completely disappeared... With a storm threatening, thanks to the geolocation feature, we made it safely to our destination. Thank you!

The cirque of lakes is majestic, these lakes are magnificent. This hike is well known, but the difficulty of access means it is not very popular.
To reach the start of the hike, you need a high-clearance vehicle, such as a Stepway, 4x4 or Duster. The track takes 20 minutes.
In my opinion, it is best to do it in an anti-clockwise direction.

We did the loop in the opposite direction to enjoy discovering the three lakes from the small pass of Peyron. A very beautiful hike with varied landscapes.

This hike is magnificent, the scenery is breathtaking: waterfalls, rivers, cliffs, forests, and of course the three lakes at the end.
We completed it in 3 hours and 35 minutes today, excluding breaks, and with just a picnic backpack, without pushing ourselves.
You just have to be patient on the trail, which can be a bit of a slog, but the reward is immense

Hello
Hike done with three people. Magnificent, a feast for the eyes, the view of the lakes is very beautiful. Just before reaching this view, we "stumbled" upon sheep and patous... According to the maps and dates posted below, this herd should not have been there, so we went around it via a scree slope.
The descent through the woods is also very beautiful.
We did the hike in the opposite direction to that indicated by previous hikers.
The only downside was the 10 km of track, which took us half an hour on the way there and the same on the way back.
This does not detract from the quality of this sublime hike.
Thanks to the author

We also did the circuit in reverse to fully enjoy the view of the Peyron Pass. We slept by Lake Ascension and we weren't the only ones there that night! The descent seemed a bit long (especially with our heavy backpacks), particularly the section of trail, but the varied scenery made up for it.

I highly recommend doing this circuit in the opposite direction, starting with the Col de Peyron, which offers a superb view of the three lakes after a steady two-hour climb. Have a picnic at one of the lakes, then descend. This descent is a bit tedious (but it's better to go down it).

I completely agree with the previous comments.
A parish-specific to Brittany, very beautiful hike, done in the opposite direction to the initial route. Magnificent views, a few marmots, the lakes are spectacular...

Undoubtedly one of the most beautiful hikes I've done in the area. The landscapes are varied, from the forest at the start to the stream, the mountain pastures, the magnificent lakes, and the rocky terrain a little higher up... The vegetation is varied, and we were able to watch a shepherd herding his sheep from afar... I did it with teenagers who also enjoyed it, even though they found it hard.
For the end, we chose the Giet trail for ease, but I regret it: the descent was steep, rocky and unpleasant. Next time, I will follow the route suggested here.

A very beautiful hike, in cloudy weather, but with remarkable scenery. Variation done in the opposite direction to the description in July 2019.
Departure from Lauzet. A slightly steep climb from the Giet chalets towards small pass du Peyron. The slope gradually levels out and the route is shaded until it reaches the mountain pasture dotted with a carpet of yellow flowers. This route has the advantage of offering a panoramic view of the lakes from small pass du Peyron. The descent to the lakes is along pleasant grassy slopes.
The descent on the return path (after passing the sharp limestone pavement) on the right bank of the Ascension torrent is quite steep and the path is stony, but shaded. Beautiful orchids can be found along the stream and in the surrounding woods. After crossing the stream (Point 2 of the description) ~ elevation 1824), the path climbs back up through the Puy woods towards Lauzet, crossing the bed of a stream that has been deeply eroded by a landslide (short passage from one side to the other, steep and slippery)

Remarks:

Good hiking boots and a pair of walking poles are recommended.

The access road from La Roche de Rame has been significantly improved and the route is now smooth, but be careful on the descent, as low-slung cars can catch their front end on the drainage channels even at slow speeds.

_
The route can also be done in the opposite direction to the description, starting from Font des Ardouis. The climb through the woods is visible in the direction of Aravet and small pass de Peyron.

A very beautiful hike, somewhat technical in places.
Requires good physical condition due to significant elevation changes and steps.
There is still quite a lot of snow in June, so equipment is recommended.
The lake is magnificent, as are the lakes in the surrounding area.
breathtaking scenery.

Hello
Same observation as id 13 regarding the descent into the woods to reach Pra Chapelle.
A very beautiful hike on little-used trails. The lakes are very wild.
Unfortunately, we had a heavy downpour on the way up to the small pass of Peyron.
This spell of bad weather dissuaded us from taking the Ducs trail, and we returned via Le Giet.

Hello, I went hiking yesterday, without taking the unmarked trail (Les Ducs) on the way back. I took the better-marked trail on the right, which leads back to Le Giet.
The access track to Lauzet is indeed completely passable by vehicle, but it is a long way (12 km) to get to Lauzet.
Info: at the red rock, the sign indicating the altitude is broken and the sign pointing to the lake no longer exists and it is not on the right but on the left that you will find the small path described in 1, which descends into the woods (follow the red arrow 8 for running), as there may be some confusion. Deforestation work is underway and there are three paths in front of us, including the one on the left marked "interdit au public" (closed to the public)! The small path is at the very end, very discreet indeed!
Otherwise, great, very beautiful hike, beautiful lakes, highly recommended!

A beautiful hike, with a bivouac at Lac de l'Ascension. The markings are somewhat confusing in the first few kilometres. The 10 km access track has been resurfaced and is now suitable for vehicles (scenic).

Hello
The return via Le Giet is indeed much better. The route described is more difficult because the path has been neglected, but it follows the route that the old shepherds used to reach the mountain pastures more quickly from Le Cougnet. It is, of course, less used, which means that you sometimes have to search for the path. That is why I specified that it should be used by experienced hikers, especially when it comes to finding the route.
