East facing lake under the Croix de Belledonne Route starts off steeply through the forest.
It opens up once you hit the cabin (with good water supply) and plentiful fields of wild blueberries just above the cabin (not ready in July).
The lake is still covered in ice in July.
Prefer September to get access to the far end of the lake for photos along the lake to the mountains over the valley. Cabane de Berger (Le Chazeau) open access unguarded hut available for sheltering in bad weather around half way up the climb. Another smaller lake on the small hill just across from the mouth of the lake with a number of good flat camping spots.
