Very pretty high altitude lake easily accessible by hiking and which can be walked around, provided you have good footwear due to the rocky terrain in places.
Great passage between Méribel and Chavières Valleys. Great view other Gébroulaz glacier, lac blanc and close to Refuge Péclet Polset.
It's ~2800m high. Carry mountain hiking equipment.
Made during a tour of the Alps with a loaded gravel bike and 40mm tires. Some portions are a little more technical but the surface is just perfect. And the view is magnificent!
