3km each way. Easy path hike, steep (~400m⇅). Decent restaurant at the top. In good weather the lake looks good to walk around. 15:30↑ 16:40-17:20 18:30↓
Tag: 6km
Parking at the Cantine des Ages 1147 Montricher. Steep walk up to the View Point. Up and Down within an hour. Goal would be to visit the Grotte, but that’s much further above. Drive then +10 minute walk to the Grotte. Equipment needed. Come back in the AM, with helmet and torches.
