The Lessy refuge is located in a true natural setting, surrounded by the Aiguille Verte and the Jalouvre peak. You can eat and spend the night there. It's a pretty incredible spot to rest after a good day of hiking!

Great view of Lac de Lessy

Highlight • Viewpoint

Path leading to Lac de Lessy with a beautiful view of the Aiguille Verte if there is no fog. At the beginning of July the grass was high but it is largely possible to pass there.
