Itinerary with a course in the forest, in alpine pastures and then on the crest line of the Grand Colombier. Exceptional panoramic view of the Alps, the Valromey and the lakes of Geneva, Annecy and Le Bourget.
Marking: yellow and white / red (GR9)
This course is fairly rolling in the typically Jura combes in the first part before becoming more technical on its ridges from the Col de Charbemènes.
It is possible to take a detour to the Fenestrez viewpoint to enjoy a bird's eye view of Lake Bourget, the Rhône and the south of Bugey.
