Located at the northern end of Lake Paladru, this wetland is fed by the Courbon stream. It is a true extension of the lake, rich in biodiversity and very pleasant.

From here begins the forbidden route to the Col de la Charmette, but aside from the somewhat technical tunnels, if you dare to defy the ban, this abandoned road offers a magnificent and entirely passable route! A timeless passage, a jewel of the Chartreuse.
