A very nice, easy walk to the Boui Boui restaurant, very welcoming, and an easy descent to the Pont St Charles. Check the bus times beforehand to get off at Val. Otherwise, take the road for 1.4 km and descend via the mountain bike trail on the left, crossing the Isère River for 40 minutes downstream, or take the bus to Le Fornet. A lovely walk to all.

There is still a lot of snow in this place even at the end of summer, and the small lake has blue reflections of ice, very pretty.
