Description of the walk

(S/E) From the Granges ski lift car park, climb up to the mountain pasture following the ski lift.
When you reach a track, turn left and continue climbing towards the Bel Air woods.

(1) After four bends, leave the track and take the path on the left that leads into the Bel Air woods. Stay on this winding path, cross the woods and you will come out onto a large open space above the cable car station and a restaurant (altitude 2,050 m).

(2) Head south into the valley, pass under the Signal chairlift, stay below the rocky outcrop on the left and arrive at the edge of an artificial reservoir.

(3) Go around the reservoir on the right and continue climbing, following a route roughly parallel to the Pyramide ski lift.

(4) Pass Col de la Platta and reach Parc de la Vanoise (wide green line on IGN map).

(5) Leave the path on the left that descends to the Refuge du Grand Plan and continue on the balcony path (unobstructed view of the Vanoise massif).

(6) Descend towards the Refuge des Lacs Merlet.

(7) Arrive at Lac Merlet inférieur, pass the lake and then start a short climb to the right towards Lac Merlet supérieur, which is ideal for a break.

(8) Descend towards the first lake and pass an intersection.

(9) Head opposite along a steep path towards the Refuge du Grand Plan.
As you approach the refuge, the path gradually widens to become a beautiful track. Pass the refuge.

(10) At a hairpin bend in the track, leave the Vanoise National Park behind you, turn left and pass close to the Grande Val chalets.
Descend the long slope into the valley, crossing the stream several times, and note the curious pile of rocks before Le Biol.

(11) Further on at Biol, leave a path on your right and continue.

(12) On a short climb, leave the path to the right towards Lac de la Rosière.

Stay on the main track to reach the chalets in the Pralin district, then the car park (S/E).

The climb to the refuge from Courchevel was very disappointing because there are roads everywhere and the last car park is very close to the almost flat balcony path that leads to the lake
The return trip downhill, although long, was very pleasant because it was wild, with no lifts and no roads
The refuge is small and the keeper very welcoming. There was an unexpected storm and he managed to take care of all the tourists, who were a little distraught

The route wasn't too obvious at first, but after that it was a very pleasant walk with beautiful views and pretty lakes. A very beautiful hike with the added bonus of marmots that weren't too wild, magnificent landscapes with views of Mont Blanc and the Vanoise glaciers. Highly recommended

Hike done in reverse. Started in the Avals Valley. Saw marmots after the Grand Plan refuge when we left the trail to climb a slightly rocky path.
The lakes are magnificent, with a preference for the upper lake
A little less interesting on the descent between the Col de la Platta and Mont Bel-Air. Road and chairlifts. The area was prettier before the work (hike done in 2010!). Fortunately, the walk through the woods after Mont Bel-Air is pleasant

A very beautiful hike with marmots as an added bonus. We stopped at the first lake because it was impossible to follow the submerged path.

Hike completed on 2 and 3 July 2022
We followed the route in reverse with a detour to see Lake Pêtre and Lake Chanrouge. We went in reverse to avoid the visual pollution of the ski lifts on the way back (I find that you see them less on the way down than on the way up).
No particular difficulties, just a slightly rough descent at the end of our route, but it wasn't very long.
We spent the night at the Grand Plan refuge. We received a very warm welcome, with a collection of slippers provided to make us feel at home. We ate very well and slept very well in very comfortable beds. Thank you to our hosts, who were very welcoming.
There were lots of marmots along the route, impossible to miss them!

We enjoyed the climb (point D->12->11->10), and this route is a beautiful hike, but if I do this hike again, I will park the car at the top of the Pyramide ski lift (near point 4 on the map) to reach the refuge and set off on all the passes that are accessible from there. This would allow us to enjoy the landscapes and sublime views of the surrounding glaciers even more and avoid the ascent and descent, which are not particularly interesting.
Enjoy the hike!

The "loop" means you have to walk back along the ski slopes, which is a little less enjoyable than the outward journey, but the view is still incredible! The best thing about this route is that we saw more marmots than hikers along the way! Please note that at this time of year, the Merlet Lakes refuge is closed if you want to stop for a drink (however, it is of course open to hikers who decide to spend the night there)

one of my favourite hikes! Magnificent scenery, a bit long and difficult for intermediate hikers like me, but the challenge is worth it and the reward at the end... Stop for a Mont Blanc beer at the little refuge near the first lake, then continue on to the second lake, which is truly magnificent, with superb colours and remnants of ice on the surface
You'll see lots of marmots!
GOOD SHOES AND WALKING STICKS RECOMMENDED

Superb hike, we slept at the Lac du Merlet refuge and extended the loop by going via Lac du Pêtre, which adds just under an hour, but it's well worth it!

The description of the route is very useful for the first part on the ski slopes, as you need to keep track of the ski lifts (there are many intersecting roads suitable for vehicles)
A magnificent hike with views of Mont Blanc and the Vanoise glaciers. You absolutely must visit the upper lake. A truly beautiful site. The return via the Grand Plan refuge and the Vallée des Avals is quite long but allows you to complete a loop

Part of the climb is done by car, which is barely feasible, but if you go very slowly, it's manageable.
A beautiful hike, but the lower lake is very low, making it a little less attractive.
Not many people at this time of year, very pretty Merlet Lakes refuge.
The climb under the ski lifts is the weak point, but after that it's a very beautiful and easy hike.

We did the hike but parked at the Ariondaz hill lake (Courchevel 1650).
To do this, drive to Courchevel 1650, follow the tarmac road that passes through the chalets and at the end of this road, follow the 4x4 track that goes up to the Ariondaz chalet. At the chalet, take the track that goes up to the right towards the top of the ski lift. Be careful, these are 4x4 tracks, so it's bumpy but you can get there!
Going up by car avoids a gruelling climb through the ski lifts on a track that serves no purpose other than to tire you out unnecessarily!

Return on foot by the same route (round trip from the lakes to the hill lake, approximately 8 km round trip)

Otherwise, it's a magnificent hike with splendid scenery. The small lakes are set in majestic surroundings, especially the second one. There are lots of marmots and not too many people
Easy hike, no difficulty, can be done with children without any problems
