Departure from Saint-Christophe-sur-Guiers (Isère)
This easy hike in summer becomes more difficult with the onset of winter conditions. A few centimetres of snow are enough to cover the markings on the ground and make it harder to progress on the steeper sections.
This hike can be done in half a day from mid-November onwards, but don't set off after 2pm, otherwise you'll need a head torch for the return journey.
