Access: From Bonneval, before the climb to the Col de l'Iseran, turn right at the Tourist Office and take the road immediately on the right to cross the Arc. Continue to the Écot car park and park before the Pont Saint-Clair (2027m).
(S/E) At the crossroads of the road and the track, take the path on the right towards the Refuge des Évettes. This runs along a meadow on the right and then joins a track. Follow it for a few metres to the right, then take the path that climbs to the left. Continue south-west, climbing gradually in a large loop and joining theGRP® Grand Tour de Haute Maurienne trail.
(1) Continue straight ahead, leaving the start on your right (steep and stony shortcut). The trail continues to climb gradually, looping to the right, then after a small drop, heads south-east and joins the Col des Évettes.
(2) Turn left towards the Refuge des Évettes. After a few metres, take the descent on the right. The trail follows the middle of the slope, passing between the refuge and the bottom of the Cirque des Évettes. Head south-east towards the Roman bridge and the Cascade de la Reculaz.
(3) Cross the bridge and head towards the bottom of the cirque for a few metres, almost to the bend on the left of the path, following the rocks on your left (turn back if you continue on the path that then passes between two large pointed boulders).
(4) Leave the trail and climb up to the left, onto a rock slab. Here begins a small, fairly well-marked trail, marked by cairns. This trail climbs steeply for the first two-thirds to reach the foot of the scree south of Mont Séti. Continue more easily along the slope towards a moraine. One last short climb before you see the lake and the glacier (pure bliss!).
(5) Continue to the right to reach the lake's spillway. Cross it via a stone ford and reach the foot of the Grand Méan glacier on the right side of the lake.
(6) From the foot of the glacier, return via the same route (S/E)
