This is a loop trail that passes through the Grand Som and, to avoid the crowds, descends along the Arête de la Suiffière (a little exposed but easy), then joins the Col de Freney (and the forest) and, via a path with numerous hairpin bends, returns just above La Correrie, our starting point.

A beautiful hike in Chartreuse that follows the route of the 120 hairpin bends to reach the Col du Frêt, before turning onto the Col de Bovinant.
In the second half of June, the flora is in full bloom: St Bruno's lilies, martagon lilies, columbines, anemones, gentians...

A magnificent hike that combines a natural section starting with a climb through the forest, continuing over the pleasant Pas de La Suiffière and then the easy but aerial ascent of the south ridge of the Grand Som, with a cultural section exploring the Monastère de la Grande Chartreuse, a veritable work of architectural art.
