Loop of the lakes at the Refuge de l'Étandard
This hike, which takes place entirely above 2,000 metres, takes you to the edge of two artificial lakes fed largely by the Saint-Sorlin Glacier, dominated by the Pic de l'Étandard.
Refuge de l'Étendard

This circular, which starts at the Col de la Croix de Fer and passes by the Refuge de l'Étendard, gives you a taste of the high mountain atmosphere. Snow cover persists for quite a long time after winter. This hike is best done in late August or September.
This hike can be easy in summer or difficult when there is snow (winter or spring). I did it when there was a lot of snow, which is why I consider it to be quite difficult.
