From Bonneval-sur-Arc, take the road to the small village of L'Ecot and park at Pont St Clair.
(S) Take the track on the right before the bridge, then at the hairpin bend continue straight ahead along the path that leads to the pastures. Keep to the right of the valley, towards La Tronna. Cross the pastures, taking care to stay on the grass. The path is well marked.
(1) Follow the Reculaz stream on the left bank.
(2) The climb becomes steeper, staying on the stone slabs overlooking the gorges. In the distance, you can see the waterfall.
(3) After 1.5 hours, leave the edge of the stream to tackle two very steep sections equipped with cables, then you will come out onto a beautiful plateau.
Turn left to discover the Roman bridge at 2,499 metres. You can cross the bridge and reach the glacier lake.
(4) Go to the foot of the glacier and retrace your steps, forming a beautiful loop to return to the refuge (cross the bridge again), passing in front of Lac des Pareis.
(5) Go to the refuge above, then continue along the path that branches off to the left until you reach the Col des Evettes.
(6) Return to the start via the gently sloping path, which can be shortened twice by taking shortcuts (S/E).
