The first part offers beautiful views of the valley, the Meije Massif and the glaciers. Then, after a pleasant climb through the alpine pastures, the moraines and the lake surrounded by glaciers will show you the high mountains up close.

 

Start out on the 'Crevasses' interpretation trail (Ecrins National Park information boards along the way), crossing first a lush, green mountainside then a steep, sometimes vertiginous mountainside.

At the junction where you join the GR54 trail , keep going forward, passing a small weather measurement station on your right.
A the next junction, shortly afte, ignore the path leading to the mountain huts and keep going on the GR54 trail. The path leads through a wide vale with alpine pastures before climbing the last switchbacks up to the Col d'Arsine. At the mountain pass, take a little path leading to the right through the meadows strewn with big rocks. Climb the terminal morain of the Arsine Glacier to reach the glacier lakes hidden behind.

Go back by the same path.
