Access: Shortly before Névache, turn right onto the D1t, Route du Col de l'Échelle, then descend to the road coming from Bardonècchia (Italy). Continue left on the small road that climbs up the Vallée Étroite to the hamlet of Les Granges, where you will find the car park.
(S) From the car park, continue along the road that leads to the hamlet of Les Granges de la Vallée Étroite, passing in front of the Refuge I Re Magi. Cross the road and continue along the track that leaves the hamlet heading north-west (GR®57). Follow this track until you reach a turn-off on the right (towards Lac Vert).
(2) Follow the track north-east to the footbridge over the Vallée Étroite stream, cross it and follow the path that climbs up to the left for a short distance, then descend behind it and arrive at the lake.
(3) Return via the same route to the car park (E).
