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!

May 26, 2023,Lac de Lessy – Lac de Lessy boucle au départ de Le Petit-Bornand-les-Glières

Very pleasant and varied hike
Be careful, however, not suitable for children because a stone is to be crossed and there are 2 steep passages with a 2m chain to pass
Apart from that the rest is accessible

June 13, 2024,Col de la Forclaz – Lac de Lessy von Glières-Val-de-Borne, Le Pteret

Strenuous but worthwhile tour with fantastic views as far as Lake Geneva. The route includes smaller sections with safety equipment.
We were lucky enough to see a ram and an ibex.
