An azure-blue lake reflecting the snow-capped peaks, the sound of tarine bells brightening up a truly mountain atmosphere: you're in the heart of the Vanoise, isolated from the world, a place where contemplation is a must!
Setting out on a trail to reach a high-altitude lake is always an end in itself, but here the route is also part of the "journey".
Starting from the grass-covered Rosuel refuge, on this mythical GR5, imagine huge rocky escarpments where you can make out man-made paths cut right into the rock.
Admire the many waterfalls along the way. Smell the tarine cows tasting the fresh green grass that makes for exceptional alpine Beaufort.
Leap like a capri over the meandering streams that feed the Ponturin. After gently crossing the numerous peat bogs, reach the Lac de La Plagne, in the heart of the Parc National de la Vanoise, where rainbow trout fishing is a must.
The refuge Entre le Lac, a former sheepfold converted in 1980, is there waiting for you. It's here, right next to the lake, that you'll spend the night.
The next day, after bubbling at the water's edge or frolicking with the marmots, you'll set off on the return journey to the other side of the Ponturin, passing alpine chalets and crossing streams along the way. You're sure to want to come back...
If you're looking for a family adventure with a donkey, check with Francis, the muleteer, before you set off.

Departure point: Refuge de Rosuel 1/ DAY 1: from "Refuge de Rosuel" to "Refuge d'Entre Le Lac" / Duration: 2h45 / Ascent: + 600 m / From Rosuel, follow the well-marked path (GR5) straight south, which rises steadily through a vast alder grove to the passage de la Rèbe (wooden platform). Excellent views of the Platières glaciers and the Nant Putors waterfall at the end of the mélézin. The path continues its steady progress through the characteristic glacial lock, then crosses an area of small limestone boulders. At the intersection, leave the GR5 and turn right. The path overlooks the meandering Ponthurin: a virtually flat section. The lake will appear at the last moment. There are plenty of places to enjoy a picnic. Continue to the Entre Le Lac refuge.
2/ DAY 2: from "Refuge d'Entre le Lac" to "Refuge de Rosuel / Time: 2h15 / Ascent: + 180 m and -775 m / From the refuge, head towards Plan de la Grassaz. Descend towards the Cabane des Mindières and then the Chalets de La Plagne. The route continues along the Ponturin until the next junction, where you turn right, then left to reach the Refuge de Rosuel. Note: as this is on the edge of the Vanoise National Park, if you have a dog, be sure to stay on the left bank. You are allowed to go as far as the Entre-le-lac refuge, but no further.
