Lac de la Partie - Vallon de Polset

A good hike with an uphill route along the Povaret torrent, away from the usual trails.
The uphill trail is well marked but there are hardly any signposts.

Description of the walk

(S/E) From the Orgère refuge car park, head north on the almost flat track. After one kilometre, just before a large bend, turn left.

(1) Follow a steep path that runs along the right bank (in the direction of the current) of the Povaret stream. Soon, a small sign indicates that you are entering the Vanoise National Park; there will be no other signs or indications for a long time.
This trail is only marked by dashes on the IGN map.
Follow the stream upstream and, once the slope becomes less steep and the horizon opens up, turn left.

(2) Join the official trail, which can be seen heading north-northwest.

(3) This trail, marked as a variant on the IGN map, will soon join theGR®55coming from the Polset valley at point 2503m.

(4) A small sign indicates the Lac de la Partie lake 15 minutes away. Follow theGR® trail leading to the Col de Chavière and turn off at the next sign indicating the lake 5 minutes away.

(5) Descend to the lake, walk around it, then climb back up to rejoin theGR® and follow it in the opposite direction until you reach the intersection that indicates the direction of Polset.

(4) Take the long descent along this path, which is theGR®55. Shortly after the Source du Vin, it enters a coniferous forest.
The trail is now less steep and more comfortable.
On the descent, you pass above the chalets of Plan du Say on the banks of the Saint Bernard stream.
Further down, the trail splits in two. A sign indicates the services of an inn called L'Estiva, which can be reached by taking either branch.

(6) Take the left fork, which is a short, steep descent, then a peaceful walk through meadows. Above the hamlet of Polset, rejoin the main path at the exit of the village and immediately after, take theGRP® variant that indicates the Orgère refuge at 45 minutes. Be careful not to descend to the road.

(7) This good path, which sometimes becomes a track, will lead you to the D106.

(8) Cross the D106 to rejoin a good track below the road. Pass above the pretty Pierre Brune chalet and a lovely drinking water spring. This will take you to theGR®5, where there are now numerous signposts. You will soon reach the car park (S/E).

Nice hike, pretty, but we got lost twice because the description wasn't clear enough. It's easy to lose the trail..

A very beautiful hike (torrents, waterfalls, lake, marmots, etc.). The route is a bit long but not technically difficult.
Just a few comments:
(1) Shortly after the start of the steep path that climbs to the left, a sign with the Vanoise Park logo, dated July 2024, indicates that for our safety, it is recommended to take the GR trail (no maintenance + herds with dogs). On this day, there were no herds or dogs.
(6) We didn't see the sign for the Estiva inn. We then took the path furthest to the right (on the left: fallen tree), then followed the GPX track above the hamlet of Polset before descending onto the path in front of the houses, as the GPX track no longer seemed to correspond to a path on the ground.
L'Estiva is one of the last houses, a few metres before point (7).

A superb hike that ends either at the pass or at the lake.
The arrival at the lake is less well marked, but it's impossible to get lost.
It's true that the climb is tough, but the descent is easy on the knees
Good hike

a superb hike, very varied, both in terms of the route (forest, trails, etc.) and the landscapes (streams, waterfalls, lakes, etc.). A real pleasure!

A very beautiful hike, partly through the forest. The landscape is varied and magnificent, and the trail is well marked.
The little village of Polset is lovely.
Highly recommended

A very beautiful route, but when we did it, there was still snow on the side of the lake, which made it difficult to follow the already somewhat tricky trail. The start of the circuit is quite steep, but the descent via the GR55 is very pleasant.

A very beautiful hike with breathtaking views of the Ruisseau Blanc waterfalls on the way back. At the start, after the relatively flat section near the Orgère refuge, the climb is relatively dry for about 1 km, then it becomes easier, although there is still a more difficult section.
Please note: at point 2, the trail is difficult to see, but fortunately the VISORANDO app helped us reach the lake without any problems, a little downstream from the planned route.
A superb lake with turquoise waters.
When we were there, there were few or no other hikers (about ten people on the entire route), and we saw quite a few marmots. Be careful on the descent after point 5, as this is a grazing area and the patous (sheepdogs) are vigilant.
The last part in the forest is very pleasant.

We did a variation, starting from Orgère, L'Estiva (steep right from the start) then Lac de Polset and Col de Chavière.
We descended via Polset and returned to the starting point. 18.5 km / 1,100 m elevation gain.
A beautiful, well-marked hike.

We did this route starting from Polset (less traffic) and going clockwise. We pushed on to the Col de Chavière, which offers a nice view. On the way back, we shortened the hike by turning off at Estiva (altitude 2,178 m), which avoids the crowds at L'Orgère and means you don't have to walk back along the road. However, the trail, although well marked and pleasant, is very steep. Take care if you have weak knees and avoid it on the way up... unless you're very fit! There isn't much wildlife. A beautiful route. Thank you.
