Description of the walk

In Aussois, head towards the Plan d'Aval and Plan d'Amont dam lakes.
Park under the Plan d'Amont dam.

(S/E) Take the path towards the Col d'Aussois.
This path, accessible to the shepherd's 4x4, runs along the western shore of the lake to its northern tip.

(1) At the Sétéria bridge, turn right towards the Refuge du Fond d'Aussois.

(2) About 200 metres further on, turn left.

(3) Further up, leave the path that climbs to the Refuge de la Dent Parrachée on your right. Continue straight ahead and follow the Saint Benoît stream until you reach the Fond d'Aussois refuge.

(4) From the refuge, you can admire the view of the pass and the "plain" you have just crossed while enjoying a coffee on the terrace of the refuge. You may even be visited by the guardian's goose.
Go back down the way you came for about 600 metres until you reach the Notre Dame des Anges chapel.

(3) Take the path on the left that climbs up to the right of the stream. As you climb, you will discover the view of the Col d'Aussois before turning towards the Refuge de la Dent Parrachée.

(5) Before reaching the refuge, take the path on the left that will lead you to Lac du Genépy at an altitude of 2,900 metres.

(6) From the lake, you can admire the Cirque du Glacier du Labby and, if you turn around, you will see the Glacier de l'Etendart.
Return via the Refuge de la Dent Parrachée.

(7) Descend to the Refuge de la Fournache.

(8) Continue along the path that runs along the edge of the Plan d'Amont lake.

(9) Be careful below the refuge, after crossing the Fournache stream, take the unmarked path on the right and do not join the 4x4 track above.
This trail will take you to the start of a ski lift, where you will descend a road to an old quarry, which you must cross before reaching the car park at the foot of the dam (S/E).

We did a bit of climbing in grey weather, despite a few sunny spells. We headed up towards the bottom of Aussois, where we turned right to the Parrachée refuge. We made the return trip before the rain set in, above the beautiful but almost empty Lake Génépy, at the foot of the old glacier (altitude 2,989 m). A nice surprise: a group of ibex basking on a large rock slab to the left of the lake!
We took a break at the magnificent Parrachée refuge overlooking the Aussois dam, then made our final descent in the rain via the Fournache refuge to the car park where we started. A very beautiful loop

The lake was frozen in mid-June, but we received a very warm welcome at both refuges and saw marmots and ibexes.

A very beautiful hike despite the heat, even though we set off early. No technical difficulties, but with a 900-metre elevation gain there and back, it's still quite a workout. Beautiful scenery.

A very beautiful hike, without a doubt. Marmots and chamois were there to greet us, and they weren't shy either — but then again, this is Vanoise! :-)
However, this hike is not "easy" but "moderate". While there are no technical difficulties, it is physically more demanding than other hikes rated "moderate" or even "difficult" on this site. To evaluate this assessment...

Incidentally, I strongly suggest that Visorando introduce a double rating system for difficulty: technical and physical. This would clarify the rating, which is otherwise too vague to be really useful.

We had planned to do this hike. However, as we were descending from the Râteau d'Aussois on 9 August, we saw an impressive rockfall on the other side of the valley, not far from Lake Génépy, which discouraged us from venturing into the area.

A very beautiful hike despite the heat, even though we left early.
We recommend doing it in reverse, as the landscapes are much prettier and you forget the climb.
No difficulty, so it's easy, but with a 900-metre elevation gain there and back, it's still quite a workout.
Everyone has their own level, but I would classify it as average because of the elevation gain.

Best regards

A very beautiful hike in a magnificent setting. The round trip to the Fond d'Aussois refuge is a very good idea, with little additional elevation gain and a beautiful crossing of meadows and wetlands (stay on the trail).
I would just like to dispute the comment in point 6 (unless we are talking about something different): when you turn around, you can see the Péclet and Polset peaks (the Etendard is more than 50 km away).
A hike to recommend

Hike completed on 15 July, very hot weather, remember to take water but you can refill at the refuge. Marmots and ibex visible around Lake Genépi. Superb views all along the route. To be repeated in May, when there will be more flowers and more snowfields.

Very beautiful route. A slight disappointment, but the author of the guidebook is not to blame! Who drank all the génépi? At this time of year, the lake is almost dry! But to our great delight, we saw two bearded vultures!

A beautiful hike with varied landscapes and stunning views of dams, waterfalls and surrounding peaks.
Lots of marmots around the refuge at the bottom of Aussois. Saw a chamois near the lake.
There are five refuges where you can easily stop for refreshments.
The first part of the hike to the Fond d'Aussois refuge is easy.
However, as the climb to the Lac du Génépy is quite steep, I would rate the difficulty level as moderate.
Warm clothing is essential around the lake due to the wind and altitude.

A very beautiful hike. The constant presence of water and snowfields at this time of year makes it even more beautiful, despite the lake still being covered in snow.

A beautiful hike where a young female ibex was "waiting for us" at the edge of the Génépi lake after we had crossed some stunning panoramas.
I slightly modified the route on the way back, going from point 8 to point 2.

Snowfields just before the La Dent Parrachée refuge and on the way to Lake Génépy. We saw a young ibex at the lake.
We went on several hikes around the dam lakes and preferred to stay up high rather than park at the dam car park. With the activity pass, you can take the ski lifts (with beautiful views of the landscape and Aussois), which means you don't need to take the car and avoid the slightly boring stretches.
Lac du Génépy is easy to find, and we saw a young ibex there. There weren't too many people on the path to Lac du Génépy. Don't forget to bring a jumper and a snack.

A very beautiful hike that I would rate as moderately difficult. Several ibexes, including some small ones, were present around the lake, allowing me to take some beautiful photos.
