Description of the walk

Start at the hamlet of Les Chenons. Park in the car park for the Balme and Fernuy cable cars, at the end of Route des Chenons.

Signposts at major junctions.

(S/E) Head west and retrace your steps along the access road to the car park (Route des Chenons). At the junction with the Route des Confins (end of the 30 km/h zone), turn right onto a grassy path (not shown on the map) which climbs towards Les Confins. The path quickly becomes stony and shaded.

(1) You’ll come out onto a small road; follow it to the right. At the crossroads, take thesecond right, a stony track still heading towards Les Confins. Pass a chalet on your right and climb gently up to a junction (signpost “Crêt Braffaz”).

(2) Continue straight on towards Les Confins, following a wide track through a sparse forest. At the next junction, turn right onto a track suitable for vehicles, heading towards Lac des Confins. Pass a restaurant on the left and arrive at the start of a zip line.

(3) Then turn sharply left towards the lake (path not shown on the map). At the junction that appears shortly afterwards, go straight on to walk round the lake in a clockwise direction (the opposite direction is of course possible). Stay on a path as close to the lake as possible. Pass the zip line landing point. Further on, cross a stream (which may be dry in summer) via a footbridge without a railing, then over a small mountain bike portage. At the fork in the road that appears immediately, take the path on the left. Join a track and follow it to the right until you reach the zip line launch point.

(3) Continue straight on along the track. At the junction taken on the way out, turn left towards Crêt Baffraz and head for the signpost bearing that name.

(2) Then turn sharply left towards Plan Lachat. You’ll come to two parallel paths: take the one on the left (the one on the right is for mountain bikes only). Enjoy a pleasant walk, roughly following the contour line. The two paths meet at a log bridge, which you must cross. Then pass under a ski lift line and ignore a path branching off to the right towards an alpine chalet. Climb up a wide track, pass under the Balme cable car line and emerge onto a vast grassy plateau.

(4) Leave the path here, pass a marker post on your right and follow a track that crosses the mountain pasture towards the clearly visible railings of the Lachat reservoir. You’ll come out onto a track; follow it to the left until you reach the reservoir.

(5) At the fork in the road near the water point, take the path on the right towards the Combe du Voret. Walk alongside the reservoir on your right and, after going about a third of the way round it (signpost), turn left onto a path that climbs steeply. When this path turns left, follow the MTB signposts no. 14 and no. 21 to the right and descend along a path that winds through the forest.

(6) When the MTB trail takes a sharp right-hand bend, leave it and continue straight on, still descending, along a path that is barely marked at first. Pass under the Fernuy cable car line and turn right; the path gives way to a track. Pass under the cable car line again and continue straight on until you reach a wide track (the IGN map is approximate here).

(7) Follow the track to the left as it descends and pass under the cable car line again. Pass a metal barrier (signpost “Sous le Bois du Merdassier”), turn sharply right towards Les Chenons and continue down the gentle slope. Pass under the Fernuy cable car line one last time, then under the Balme cable car line. Go round the lower station of this cable car on the right and return to the car park at the hamlet of Les Chenons (S/E).

Notes

Ensure you have at least a good pair of trainers.

Water point at the Retenue du Lachat. Picnic tables around Lac des Confins and the Retenue du Lachat.

A detailed map is useful (at the very least the one accompanying this description).

Alternatives:
Avoid Lac des Confins (very busy in summer) – At the “Crêt Baffraz” signpost (2), turn right towards Plan Lacha. Then follow the main route from the second signpost at (2).
Return entirely via an alpine track – At the Retenue du Lachat (5), head down the track towards Les Chenons. After a left-hand bend, rejoin the main route at (7).

easy hike. A little disappointed by the lake, nothing exceptional, and far too crowded for our liking.

A very beautiful walk, even if the Lachat reservoir is nothing special.

A rather pleasant walk. I didn't particularly like the downhill path.
Strangely enough, I preferred the reservoir to the lake.

A beautiful hike... on small, separate mountain bike trails, which was very enjoyable.
It was a shame for us because the weather wasn't great.

Shortly after setting off, the trail is closed. We have to turn back without knowing where to go. We eventually find a path to rejoin the route. On the way back, it's a narrow path full of large tree roots and uninteresting because we can't see the scenery on the right (Mont Blanc) or the meadows and animals on the left.

Hike done in March with some areas still covered in snow. At one point, the route passes through the ski slopes of La Clusaz. A pleasant, very accessible walk at the foot of the Aravis mountains

We chose this hike because we were accompanied by someone who had difficulty walking. This hike was rated "easy". Thank you. We didn't complete the entire hike...
