Successful summit on foot and skis but access wasn't great. I wont share details except that what I was marked on Google Maps as a road turned out to be a private lane. Trail is a road/ATV trail with varying surface quality (smooth to very rocky/eroded). The last km is steep bushwhacking though there may have once been a trail or road to the summit. The preferred route is probably from Lac de l'Aigle at Chemin du Lac Serpent which is a longer route but access remains on public land. Parking access is uncertain. Summer summit attempts are likely to include water and mud. Makes for a fun ski route with enough snow on the ground.
