Walking itinerary : Loop around the Case d'Oche lake
IGN cards
Description
A magnificent hike to feel close to the mountain. Meet at the foot of the Dent d'Oche from Bernex to the chalets and then to the lakes, where you may see marmots.
Starting from the Fétiuère car park in the commune of Bernex, this hike will take you to discover two mountain lakes.
You will first reach the Chalet d'Oche and its mountain pasture, and then the Lac de la Case, which is frequented by marmots. Keep your eyes and ears open, you may be lucky enough to spot one, or hear one whistling!
You will then take the Case d'Oche pass and its panorama of Mont Blanc and Lake Geneva before crossing the Darbon mountain pastures to reach the second lake of your walk: Lake Darbon, situated at an altitude of over 1800 m.
A final effort awaits you up to the Combe de Darbon and the pass of Portes d'Oche before starting your descent to the Lac de la Case.
