Achard lake
With an air of Canadian rocky mountains, this pretty mountain lake is easily visible from the Col de l'Infernet and Croix de Chamrousse in summer, and snow-covered in winter.
Lac Achard: 1,917 meters above sea level and 1.28 hectares in surface area.
It can be explored on foot or on snowshoes in winter. It consists of a main lake in the form of a series of small lakes that are in the process of being filled in (the exact name is Achard Lakes). In fine weather, you'll have an exceptional view of the Taillefer massif.
Lac Achard is part of the Espace Naturel Sensible (ENS) "Plateau de l'Arselle et lac Achard". It is also located in a Natura 2000 zone.
Fire, collecting wood, camping, gathering, fishing and swimming (even for dogs) are strictly forbidden (subject to fines). Dogs must be kept on a leash. Bivouacs are permitted from sunset to sunrise, from 7pm to 9am (except from May 1 to October 31 + Infernet area).
Please stay on the trails to preserve these fragile environments.
