The hike starts at the end of the road that leads to the recently built Refuge du Lac de la Grande Léchère.
However, it is advisable to park in the car park at the side of the road, from where a small path leads to the start of the hike in 7 minutes.
(S/E) Follow the mountain track for about 4 km until you reach the signpost for Mère des Eaux at an altitude of 2,010 m, ignoring the tracks and paths that branch off to either side. This is a moderately ascending balcony track offering unobstructed views.
(1) On the way, you will pass a chalet used by shepherds. Continue on until you reach Mère des Eaux.
(2) Continue along the path on the left, which climbs a little more steeply to La crête Maxet (sign at an altitude of 2,100 m), allowing a good twenty minutes.
(3) Turn sharply left towards Col de Montjoie, which you will reach in about thirty minutes.
(4) Descend via the same route.
(5) At an altitude of 1820m, leave the track and take a path that climbs up to the right towards Grand Praz, initially heading south.
Reach Grand Praz and take a contemplative break there.
(6) Locate an isolated chalet and continue your descent along a barely visible path through the meadow. It faces almost due south and leads to another chalet.
(7) Pass under the chalet and take a path that initially heads east, then turns south-west to rejoin the track.
(8) At the Prés de la Pierre sign, continue downhill to reach Lac de la Grande Lauzière.
(9) Retrace your steps to return to the starting point (S/E).
