This is an unusual stage, as we start by descending into the Borne valley at Entremont, and then make the long ascent to Lac de Lessy. A little more distance than the day before, and a little more ascent.
This third stage, starting from the Plateau des Glières, takes you to the Lessy lake and refuge.
You'll make your way through the Borne valley, passing the site of Montriévray, a heroic battleground during the attack on the plateau in March 1944, before arriving at Entremont.
Finally, you'll reach the Col de la Forclaz, where you'll be treated to an exceptional view of the Lac de Lessy, a natural site that is home to an important pastoral activity.
The Lac de Lessy and its refuge, nestled in the foothills of the Pic de Jallouvre, are the high point of this day.
Swimming in Lac de Lessy is forbidden, as its fragile ecosystem must not be disturbed!
Whichever hike you choose, remember to take a rucksack packed with cereal bars, sufficient water, sunglasses, sun cream, a little first aid kit as well as appropriate clothing according to the season and weather forecast.
