Park in the car park on the edge of the D1091.
(S/E) From the car park, take the path heading south.
(1) Turn right onto the path that runs along the hillside. This path, known as the "Sentier des Crevasses", winds its way through the mountain pastures, facing the Meije and Pic Gaspard massifs. There are no intersections with other paths.
(2) After a viewpoint facing the Meije massif, the trail turns south. While remaining almost flat, it becomes a little more challenging as it follows a narrow ledge 400 metres above the Romanche river (not recommended for those prone to vertigo!).
(3) Cross the Ruisseau du Colombier stream (a slightly tricky passage). The trail finally reaches a mountain pasture and crosses theGR®54, which descends towards La Grave.
(4) Continue straight ahead.
(5) Ignore the trail that descends to the right towards the Refuge de l'Alpe de Villar-d'Arêne and continue straight ahead on theGR®54. Opposite you is the magnificent glacier-covered summit of Montagne des Agneaux. Continue to Col d'Arsine.
(6) Take the path on your right. You will leave theGR®54and walk between large boulders. After about 400 metres, the path climbs along the grey glacial moraine and leads you to the Arsine Glacier lake.
(7) To return, simply retrace your steps to descend back to the car park (S/E).
